Best 2015 Lincoln Navigator Vehicle Suspensions

I’ve struggled with crushing my airbags and having the pump for the airbags burn up trying to keep up and hold the trailer. Using these have absolutely made all of the difference in no longer looks like Sanford and son and the trailer/vehicle stays level. I pull a 36 foot travel trailer weighs almost 8000 pounds with a Lincoln navigator. Absolutely the best thing I’ve installed to support trailer towing.

Installed this on my 2001 Explorer. Install is easy (assemble unit, bolt on in place of existing bump stop). Annoyed to find it doesn't fit. Specs are gap 1/2"-1-1/2"; there was a gap of 2-3/4". Yeah, they sell spacers for $27 each, but it's really annoying to buy a $225 product that says it fits your truck, only to find that you have to spend 50% more to actually adapt it to your truck!

Two things: a special tubing cutter needs to be furnished with each kit—99% of leaks are caused by bad joints at the fittings; The metal parts need to be hot dipped galvanized base coat and powder coated on top layer. The system would be nearly perfect if they didn’t succumb to corrosion! Otherwise, I love mine!! DSW

Product was as described. Installation video was most helpful as were the written instructions. Bending the bolt plates was absolutely necessary and was the most difficult part of the installation. I dropped one inside the frame, after retrieving, 30 minutes later, I drilled small holes in the handles and put a piece of wire thru them so they could be easily retrived if dropped again. Tested as recommended with 70 lbs of pressure and the truck's rear end popped up about 4-5 inches! Can't wait to try then with the trailer!

OEM springs not strong enough. After installed feels a lot stiffer and raised the back 2". Material looks really good. Installation done in 40 min using a nut driver, a flat head screw driver and hand soap. I did have to take wheel off it just makes like easier.

2005 Honda Cr-V, they went on pretty easy, it was a tight fit but no trimming required. I jacked the car up on some stands, had both sides installed and zip tied in 45 minutes..

I installed a set of 1125 Sumo Springs in the rear coils of my Toyota RAV4 Limited Hybrid AWD to increase the spring rate ahead of a cross-country road trip. My RAV4 really sags with a rearward rake when passengers + rear cargo are loaded in the vehicle. This impacts the handling of the vehicle and throws off the aim of my headlights, which leads to other drivers flashing their high beams at me as my headlamps are shining in their eyes. Hopefully these Sumo Springs solve that problem. I’ve driven about 50 miles post install and can tell the ride is much more firm and stiffened up in the rear of the vehicle. The RAV4 feels much more sporty and planted. The install was much more difficult compared to my Sienna. In our van, the Sumo Springs slid right into place - it was a 10 minute job and I didn’t need to remove the wheels. On the RAV4, this was not the case. I had to remove the rear wheels to gain enough space to work the Sumo Springs into position between the coils. The fit was also much more tight; I had to really jam the Sumos into place and slide them into the center of the coil (it was a real arm workout). The Sumo Springs also overlapped about 2”, so I removed and trimmed each down with a razor knife to achieve a ~.5” overlap (per the supplied instructions). Install time was about 90 minutes as I had to remove the Sumos and trim them - which doubled my labor time. Time will tell to see if these work, but I’ve had a set of Sumos in my Sienna for about 15k miles / 1-year and they have done just fine, so I suspect these will too.

I installed these on my stock 2019 Outback hoping it would level out the rear sag when towing small teardrop trailer. Man, total game changer! Towing was fine prior to install but didn't like my headlights pointing up with rear sag. Installation was fairly easy. I say fairly because on my Limited the springs didn't allow much room. It required using a flathead screwdriver to get them seated. Took about an hour and most of that was lifting behind removing wheels. Feels and looks 100% better without the need for new overload springs. Highly recommend Before and after photos. One with skybox is before

Initial reaction is positive - I installed front and rear sumo helper springs yesterday (5-23-19) and did a test drive around the block. The side to side pitching of our Transit Class B+ motorhome was greatly reduced. I still need to test on highway. I did not install the optional spacers that increase the ride height and reaction time of the rear sumo springs. The spacers will be added later if needed.

Just finished installing these on my 2014 Ford Expedition EL Limited. Very easy to install. Never removed the wheel to install. Jacked the vehicle up one side at a time and did the install. Haven't hooked to my 30ft camper yet to see how they work. Will update after my trip in July.

These Sumo Springs were easy to install, even for a 70 year old guy. I tow a 7,000lb camper and even tho I have a nice WDH I still had som sag on my Tundra. These helped level it out when towing and got rid of “some” of the bounce. They were really a godsend when I overloaded the bed with about 2,000lbs of pavers. That weight squished the Sumos significantly but the truck drove and rode great. Better and less expensive than air bags.

Pros: Easy install Drastically helps with sag when towing trailers Cons: Things feel more bouncy in the back when not loaded They get hard as a rock in freezing temperatures (i.e. 15*F = no rear suspension) No option to unscrew the spring and replace with bump stop for the winter (at least that I can find, tell me if they make one).

Fit great on my 2013 Tucson rear springs...don't bottom out now with motorcycle carrier on the hitch...easy to install from the side with the wheels off.

The SumoSprings have reduced the sway when turning. Also, I am not being pushed sideways when a truck passes or during wind gusts as much as prior to installation. But, I think if I do the front springs I would see even more improvement. So, I have seen improvement but I believe more improvements are possible. I had an rv dealership install the SumoSprings at a cost of $250. The installation is relatively easy. I wish I had done it myself. But, I’m 76 and not as agile as I used to be.

Sumo springs are an excellent product. I installed them myself and found them easy to install. The difference in stability was night and day. They took most of the sway away and it handles much better on the freeway. We’ve had them on for a year now and they still perform perfectly. I would recommend them to anyone with a gas powered class A. Etrailer was very helpful because it’s important to get the correct Sumo Springs for the weight rating of your coach.

Well put them on Friday night and went to put the inside frame bracket on and the bracket was way to big and wouldn’t fit. So we had to cut 1/2 out of each bracket and reweld them to then to fit inside the frame rail. To say I’m very unhappy would be an understatement. Not sure if I was packed wrong or what but very displeased with fitment. 2007 Chevy 1500 classic

Thank You very Much Patrick Everything was great and undamaged Thank u for the quick for the package to get here ..... From Robert L. Stevens

Excellent material and the installation instructions were very clear and to the point with the best pictures that coincided with the written material. Only took me 2.5 hours from the start of assembling the air bags with the hardware on the workbench to putting away my tools! This is on my '04 dodge 3500 dually that will be handling my new Host Mammoth Slide in Camper that will set at apprx. 5000 lbs.! Beautiful to maintain level truck and to know that the springs are not collapsed and wearing them down prematurely as well as providing a safe handling truck when on the road.

This is a great system that is pretty easy to install for the average garage mechanic. Installed on a 2018 Ram Mega Cab with 6.7. 30 PSI in the bags and it eliminates the squat when pulling my fifth wheel. One year in and still works great with no air loss from week to week. In my opinion upgrading to the braided lines was just inexpensive insurance.

I FIT THESE ON A NISSAN NV 3500. IT TOOK SOME WELDING ( THERE IS NOT A MODEL FOR THESE BUT MY MECHANIC KNEW HE COULD MAKE IT FIT). THEY ARE GREAT!! YOU CANT OVER LOAD THE TRUCK I KEEP IT AT 70 PSI. I ALSO FITTED AN ELECTRIC COMPRESSOR AND AN ADJUSTABLE 1/4 INCH REGULATOR AND DONT NEED ANY ADJUSTMENT.

Easy install great fit. Put them on our 04 E450 rv that we take to Old Mexico twice a year on some hideous roads. They’re worth every penny and rides so much better.

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

You van feel the difference right away. Gave my truck a little more height without a load. Truck feels more stable a turn/curve. I still have to put a load on it to check the differences. But, I imagine I won't have any problems based on everyone's else's reviews.

The springs work amazingly, I made the installation a little harder by not reading the instructions completely. But after a phone call and a little guidance I had them on in no time. Thanks to Ashley and Jill for their help and patience.
