Best Ford F-250 Super Duty Vehicle Suspensions

Jesse M gave me expert advice and answered all my questions regarding the Timbren rear suspension enhancement system. I ordered the Timbrens and it took me a little over half an hour to install myself. I absolutely love the way the Timbrens leveled my sagging truck and greatly improved the stability of my ride. I carry a 2003 Northstar tc1000 pop-up camper on my 8ft bed. I highly recommend the Timbren rear suspension enhancement system. I attached a before and after photo.

Works well. Helped with rear end sag from 1000lb tongue weight on my 2012 f250 6.7 crewcab. Ride quality and stability towing has improved as well. Very easy to install.

Mostly raves about etrailer rather than the air bags. 2nd set of these for my 4wd f250’s I use the2wd model so I can keep my factory bump stops and move the bags further outward. They fit my trucks perfectly and I also run the day star saddles so if my truck needs to articulate , it will not cause damage. As always e trailer has the best price coupled with super fast shipping and after purchase support.

Overall very pleased with these air bags. I did add an on board air compressor to allow easy adjustment as I pull anything from a 16,000# fifth wheel, to a 10,000 car trailer to a boat trailer. The ability to adjust with the on board compressor just added convenience to an often used set of air bags.

The installation video is very helpful however, when the tech in the video said there may be some modifications needed he was not kidding. The level of work is quite a bit and do it yourself people should know it can get a little complicated especially if you do not have a lift. Thank you for a nice product. Works very well.

This system I installed on my 2012 Ford F-450 dually pickup. I love it!! I replaced a air bag system that I had put on by so called professionals. It was terrible. It mounted under the spring shackles. It helped when puling a heavy loaded trailer but rode terrible otherwise. The system I bought from e-trailer uses air bags under the rear axles. It handles heavy loads when air up to 90 psi and rides smooth when empty at 25 psi. I recommend it highly.

Was able to install these with a 15mm flex head ratchet wrench and lifted the rear of the truck to make it easier. 30 minutes to take off 4 nuts and put em back on. 2 minutes assembling the timbrens with the added spacer. I have a f350 with a salter and plow. Loaded with salt the lights shoot up and in the snow ?? it’s like hitting hyper drive and you’re blinded. These helped big time. Very happy so far.

These are great, put 1500 # of bagged concrete in truck They just were touching the stop bar, stability was what I expected Can’t wait to our RV hooked up and hit the road Took as long to set up the jack as to install these load stabilizer items

Just finished the install this afternoon, but everything seems good. The directions were very easy to follow. I found I needed to let things settle into place (loosening bolts and making adjustments), and now all seems good. I drilled holes just above the license plate screws to install the air input valves. Looks great.

I am a 63 year old retired refrigeration mechanic and a DYI guy. These were easy to install an are working good took out the sway when my camper is on I also purchased the frame mounted camper tie down

Works great. Easy to install.

These bags are amazing. Make the rear end ride pretty rough so I put deaver add a packs from carli and did the day star buckets for the bags. Now they are connected when I need them, and disconnected when I dont. Pretty awesome set up. I've put 5200 pounds of rock in the bed of my truck, the rock yard thought I was crazy but then I aired up the bags. You should of seen their faces. Rode level, sat at about 85 psi and rode like a caddy.

After emails with firestone, in which many disagreements came to light. My vehicle is a 2002 f350 dually Crew cab 8ft bed, completely stock no alterations at all. First issue was the emergency brake Cable was in the way. I rerouted the cable sent photos to firestone. The person in which I communicated with, stated that my brake line was not stock OEM. The emergency brake cable was the issue not brake line and the person at firestone doesn't know the difference between brake cable and line. In the photo sent showed my rear brake line that was just replaced and it was shiny. The brake line replacement was OEM. The brake line was not an issue at all. I have photos showing how we had to modify the firestone air bags set up. I welded straight to the axle. The bags will work now after hours of mods....if anyone else has a vehicle like the one stated above please let them know mods will be required. This isn't my first issue with firestone air bags. I had to prove to firestone that I had a pin hole in a seam on a air bag. I had to submerge the air bag in water, take a video and send it to them. They did send a replacement after a while. Just had to say this.......

2003 Ford F250 CC FX4. This kit came with the wrong lower and saddle brackets. After reading the other reviews, I see I’m not the only one with this problem. I had to do heavy alteration and remanufactured the brackets to fit. Otherwise I’d give it fives stars.

This set was a replacement for the ones on my F350 that were already on the truck. Everything went back together with ease once the old bracket were removed. With one air compressor air is is delivered to the air-ride system one the truck is started. I pill a fifth-wheel with a tongue weight of around 3600 pounds. With this system I'm able to level out the truck.

Installation took about 2.5 hours with just me installing it. Install went smooth and all the parts and hardware were correct. Driver side took longer than the passenger side. Also located the air fill valves inside the gas fill lid for easy access. Have not put a load on the truck yet but should not be an issue. The last 2 photos is where I installed the air fill valves.

Towed my 12k fifth wheel with my '23 super duty once before purchasing these. Night and day difference! The springs reduced the side to side sway and wallowy ride. My initial tow it felt more like a bumper pull than fifth wheel, now back to feeling very stable. The truck still squats pretty good but not as much.

While these worked great for the first few months and helped level the load, they have now become deformed and squished out of shape permanently. We have a slide in camper that is on the truck for only for trips otherwise the truck is unloaded and off the bumps. I did not expect them to deform so much, and so easily after only a year of use.

Good product, quick service. Took a couple hrs to install and very happy with the results

Air Lift air springs are good and dependable, use them for the last 25 years on three pick-ups always worked great. My complaint would be against the lousy packaging which came with two or three holes and all messed up, luckily all that was missing was one washer.

When it arrived the box was open but FedEx did an excellent job and everything was still inside, the boxes should be strapped they're only glued. But the product is excellent, on a 2023 F450 it was perfect fitment. The airbags are well made and provide for a smooth ride, it helped my shaking issue at highway speeds.

I just bought a new 2019 Ford F250 to pull my new fifth wheel. The pin weight of the fifth wheel caused the bed of my truck to drop a few inches so I bought the Air Lift LoadLifter 5000 Helper Springs and the Air Lift One wireless on board compressor to raise the bed back up to level. I installed all of it myself after watching the etrailer installation videos. I think somewhere they mention it being a 2-3 hour job. Well...if you do it every day, then it probably is. It took me the better part of a day to get it done. The first thing i did was remove the spare tire for easier access. I also tried to install the airbags without lifting the truck. Actually, I did install one side without lifting and it wasn't that hard. However, there is a nut on the bottom bracket that is between the airbag and the leaf spring that is impossible to tighten without lifting the truck body. Even after lifting the body, it was still very difficult to access/tighten. Instead of drilling a hole for the schrader valve, I used a couple of oversized washers and installed it in a hole on the hitch frame that was already there. The Air Lift One, I installed on the frame, on the drivers side of the vehicle and just forward of the gas tank. This is really about the only place on the frame without wiring of some sort. I got the EZ mount but didn't use the large U-bolt as I didn't find any place it would work. Instead, i just drilled a couple of starter holes in the frame and used the provided self-tapping screws. I also wired the hot and always-on wires together and directly to an upfitter wire under the hood. I had no trouble getting the wireless remote to communicate with the compressor and it works great. Now, with my fifth wheel attached to the truck, I can add air and level the truck back to factory heights. Overall, the install wasn't that hard and would have been super easy with a truck lift. The people at etrailer were great when made my order and will definitely give them a call again.

Well, let me start off by saying up front, that if you plan on installing this kit by yourself without a car lift, your going to be doing a lot! of crawling around under the vehicle. I started at 9am and finished at 5:30 with no breaks. Hard work for a 65 year old dude. Remove both tires and the spare for easy access. Whom ever put together the instructions for install did an absolutely excellent job! They were very easy to understand and concise. The photos where spot on and clear FOR MY VEHICAL. Not some generic photo that covers any vehicle. The kit was very well put together with all the parts required to assemble everything. I didn't have to supply or substitute any nut, bolt or fitting. Once the kit and the pump was finished being installed, I powered it up and inflated the bags. There where no leaks and everything thing worked perfectly. This is a first for most anything I install, seems like I most always screw up the installation or have to reengineer the kit to fit my needs. Not this time! Everything went together great and worked awesome. My hat's off to the team that designed and put this kit together and to Rochelle in customer service, who was professional and kind in helping me get the right suspension kit for my truck. Thanks to all the folks at etrailer you know what your doing and live up to they hype. BTW I learned about this kit on You Tube from a full time RV'er.

I have a 2020 Ford F-250 Lariat FX diesel and I pull a 2022 Jayco Eagle HT fifth wheel with a GVWR of 10,995 lbs. I noticed when I was hooked up to my trailer and raised my landing gear the back of my truck would squat causing my headlights to shine somewhat into the sky and sometimes while traveling the interstate in construction zones the ride was rough. So I decided to add airbags. I chose the Air Lift Load Lifter 7500 XL Air helper springs(#AL55FJ). I had them installed by a local garage and he did a great job installing them. I love the end result a much smoother ride and the braking seems smoother also I can easily level off my truck with the 7500 XL Air lift system allowing my headlights to shine straight out now. I give these guys five stars. In addition to adding the Air Lift 7500 XL system I also had the Air Lift Wireless Air compressor System(#AL58WQ) installed and it is Bluetooth, compatible on my iPhone which is amazing. I can control the lift on my bags individually or paired together with the touch of my phone. No stopping and getting out in the rain or looking for an air hose. I can sit in my cab or get out and increase or decrease the amount of air in my Air Lift system. I can also do it manually if I so choose. In the photo you can see where I mounted the two air fitting on my crossmember right below the compressor on the frame. There were already two holes there so and can be accessed easily. I am very satisfied with my compressor system and I give this a thumbs up in addition to the five stars.

Not driven under load, but think it is the answer. I may have to remove the spacer. I had to have them installed, not as easy /smooth as their video portrays. The instructions do not advise as what it suppose to look like (for F350 SRW) . IE: barely touching the axel? Above the axle? The 2800 load was recommended, I will follow up after my RV trip. I want it to set level, but not ride stiff W/O a load.

So managing a travel nurse's life we tow all over the country.. The Sumo spring has helped tremendously with ride level and stability for tens of thousands of miles in this first year.. With no hassle of leaky air hoses or blown bags along your ride it is by far one of the easiest ways to help support your load!!!!

Had a problem with parts missing was taken care of and parts were sent right away I buy everything I need for my trucks and trailers from y’all quick shipping and great help Thank Yoi

Easy to install

I installed the 2500# Super Springs on my 2019 and 2021 F250s. Installation was simple and made both truck ride smoother unloaded. Help tremendously with heavy trailers.

Installing these on a 2020 F250 was easier than I thought it would be. I was able to get the springs on whit the center piece and the front shackle bolted without jacking up the truck. I had to jack the frame up a few inches on each side to get the back shackle bolt through. I put the shackle bolts through the bottom holes since I only need the extra support when I tow. I recommend air / power tools for the shackle nuts and it doesn’t hurt using them for the center bracket u bolts. They are lock nuts and they have a long way to run on for each bolt. I did have to bend my parking brake cable hangar out a bit for one of the shackle bolts to clear the cable. The truck seems to sit a little higher in the back. Maybe an inch or so. The ride empty seemed the same except it felt like it didn’t roll quite as much when turning. Rolling over a lip at the end of our driveway the extra stiffness was noticeable, however. I won’t know how well they really work until I get my fifth wheel hooked up.

great product, gave me the extra lift I needed when hauling my 4,000 plus truck camper. I'm riding level with no sag.

The air bags fit nicely and work as expected. The only reason for not giving 5 stars is the directions… written and the video. You definitely need to have some logic and mechanical skills but it all works. Trying this without a lift (rack) is not a good idea. Madison, my customer service rep was exceptional and got the product to me early. I would definitely use this company again.

Phone support to get questions answered before ordering was excellent. Shipment and reciept was extrodinary fast. Had them installed prefessionallY, it was a first time for my mechanic..he said instructions were very clear. install took 3 hours.Truck sits at better height, rides better..can't wait to hook up 5th wheel

Installed on 2014 F350 4WD crew cab. I did this installation myself with jack stands and a good floor jack. Instructions were pretty clear in most respects although I would not recommend taking this on if you're not a good mechanic and have the proper tools. Installation time for me was about 8 hours. I'm very satisfied with the product as I haul a 12,000 lb. boat trailer and now can level the truck with the trailer attached. I also can correct the left side low issue with the 55 gal. fuel tank filled. Just completed a 5000 + mile journey pulling the boat with no issues. This is a quality product that performs as advertised.

An excellent solution for leveling my tow vehicle! The road active suspension system definitely improved both the ride and the leveling of my vehicle!

When I ordered the RAS , I was told that it would fit in place even with my existing Firestone Air spring , and the brackets from the RAS don’t pass beside the air suspension !

Having been in the auto/truck repair business for over 50 years, I thought this would be a good Idea so I tried it. I could have made my own but it would be a lot of cutting and drilling because it is so many pieces. I used it to add capacity so I could haul my camper that I purchased three states away and had to pick up. I used 2 of the 3 plates because there wasn’t enough room for three. It did very well like that but after I got back I added the 3rd plate figuring I could use the third one by just jacking the truck slightly before engaging. I thought all three woul be needed once the camper was full of water and gear. I am enclosing a picture of how ti drill the springs with using the vehicles own drill press (screw jack) for changing tires. I still need to test fully loaded and with all three plates in place.

The front brackets did not fit my stock 2005 F3 15 the down rods for the anti-sway bar were too close to the leaves springs to allow clearance for these stable load additions. Customer Service told me that they have never seen this problem before, that is hard to believe with all of the F350s on the road. However, I was told that I could use the rear plates on their own.

Makes for a very rough ride without weight in the rear of the truck. Fit was not as advertised had to jack up the rear of the truck just to get them on not even half inch of space. But they do help with the weight of my camper in the back of my truck.

A year ago, I added Timbrens to my '09 F350 to help carry a '09 Lance 915 camper. Since my truck is a CC LB diesel model, the truck payload and loaded weight of my camper are similar. I found the Timbrens a cost effective way to limit the suspension sag and improve truck/camper sway. When unloaded, I rarely notice the Timbrens as they are ~1.5" away from the spring pack stop and only engage on large bumps. I also like the maintenance free aspect of Timbrens. To further enhance the loaded ride, I am replacing the thin factory contact pads on my overload springs with larger ones. I found that adding the Timbrens limited suspension travel such that it prevented adequate overload spring engagement with the factory pads. The replacement overload pads from Torklift and Supersprings are 3" (too much IMO as they contact the overload spring nearly all the time making for a rough ride). I am cutting down a set of Superstops to ~1.5 - 2" for the right amount of overload spring contact and Timbren engagement but still maintaining unloaded ride quality.
