Vehicle Suspension

At etrailer.com, We Enhance Your Ride—From Suspension Upgrades to Smooth Travels.Are you a frequent heavy-duty tower with a big truck? Invest in a set of zero-maintenance jounce springs designed for heavy loads. Or maybe your SUV or van just needs a little help hauling your boat trailer or pop-up camper a few times a year? A set of coil springs will do wonders for your ride. You can even control your air spring suspension kit from your cab with a Firestone Air Command compressor kit. With over 75 years of assisting our neighbors and customers, over 1 million photos and videos taken to make sure you’re getting exactly what you need, and over 35 thousand installations completed, we’ve got the product know-how and experience to help you make the right choices for the job at hand. How can I improve my vehicle's suspension for towing heavy loads?Adding Air helper springs or Helper leaf springs can reduce sag and improve stability when towing. Air springs let you adjust the firmness based on your load, keeping your ride level whether you’re towing or driving empty. Helper leaf springs offer additional support to existing leaf springs, reducing sag and improving stability. Both options help improve handling, braking, and overall ride comfort when hauling heavy loads. What are the benefits of installing an anti-sway bar?An anti-sway bar educes body roll when cornering, making your vehicle feel more stable and controlled—especially if you drive a truck or SUV with a higher center of gravity. This upgrade is particularly useful when towing or hauling heavy loads, as it helps keep the vehicle level and responsive. If you experience swaying or excessive leaning on turns, an anti-sway bar can make a noticeable difference in handling.How do I know which suspension enhancement fits my vehicle?The right suspension upgrade depends on your vehicle’s make, model, and how you use it. If you frequently tow or carry heavy cargo, air springs or overload springs can help. If body roll is an issue, an anti-sway bar is a great addition. The best way to find the right fit is to check your vehicle’s suspension type and weight capacity. For more information on picking the right suspension, check out our guide.Can I install suspension upgrades myself, or do I need professional help?Many suspension upgrades, like air helper springs and anti-sway bars, come with detailed instructions and can be installed by a confident DIYer. If you're comfortable working with basic tools and lifting your vehicle safely, you can handle most installations at home. However, if you’re unsure or don’t have the right tools, you can find a local professional using our installer locator.Will suspension enhancements affect my vehicle's ride quality when not towing?Most suspension upgrades are designed to improve load handling without sacrificing comfort when driving unloaded. Air springs can be deflated when you’re not towing, keeping the ride soft. Upgraded shocks and sway bars improve stability all the time, not just when carrying extra weight. The key is choosing the right setup for how you use your vehicle.
