## Description

The RAS RoadActive Suspension HD rear leaf spring upgrade is the only suspension upgrade that improves towing and hauling performance without stiffening your unloaded ride. Unlike traditional add-ons, RAS works with and strengthens factory leaf springs by 40-50%, eliminating squat, reducing bounce, and increasing stability for better driver control. This mechanically active system works instantly to support your truck’s suspension, maintaining proper leaf spring arch while absorbing and dissipating load force energy. No adjustments, no maintenance—just install and enjoy a smoother, more stable ride. Heavy-duty and ideal for towing and hauling, RAS is the only system that guarantees 100% ride comfort and performance, loaded or unloaded.

Review: Put this on a 2020 Silverado 1500 Custom Trail Boss. Double Cab, 4.3, 6L80, 4x4. To preface, all hardware comes loosely installed. I had no missing parts. It’s worth the money if you don’t want to go with helper bags. It’s a poor man’s overload spring and is worth every penny. No squat. If you’re towing ANY kind of trailer, especially with the trail boss suspension, buy it. If you don’t have a sway bar, buy it. If you DO have a sway bar. Buy it. First off, this was extremely easy to install. The instructions were clear and concise. I was done in 30 minutes. Ride quality with no trailer is unaffected (weird, but I’ve put thousands of miles on this truck since install), and the rear ride height was raised by 1”. Even hauling a single axle enclosed trailer, you can tell the difference. It’s soft when you need it to be. It doesn’t squat under load. It does the job it’s intended for, and does it extremely well. I combined this with the Hellwig sway bar kit, and let me tell you…Chevrolet needs to pay attention and take notes.
Review: RAS has been installed, so far everything is excellent. No more air bag hassles. RAS is maintenance free.

A: Beware of imitation kits sold online. Only genuine RoadActive Suspension products have been engineered, tested, and warrantied in North Carolina since 1998. Listings with RAS in the title are genuine RoadActive Suspension products.

**Q: How much does RAS increase payload capacity?**
A: While RAS can strengthen the rear suspension by up to 50% in a progressive manner and can improve the way your truck handles loads; it and no other suspension upgrade can increase the manufacturer weight ratings.

**Q: Will RAS fit my lifted truck?**
A: From a fitment standpoint, RAS often fits lifted trucks without an issue. Before ordering for your lifted truck, be sure to check your suspension for possible obstructions. If there appears to be an issue please contact RAS directly for assistance.

**Q: Will RAS help reduce my rear squat?**
A: Yes! While RAS is geared towards improving overall load handling, stability, and performance without hassle; RAS will also help reduce rear squat by up to 2-3 inches.

**Q: How is RAS different from other suspension helpers such as air bags?**
A: RAS offers a more complete solution, where enhancing stability, reducing rear squat, dampening excessive rebound, improving performance, and providing same-as or better-than-stock ride is just as important as reducing rear squat.

*by B***T on 2 December 2025*

I bought these in place of air bags that I was looking at. Im very happy with the results, especially at a third of the cost. Took about 1 hour to install with not hitting it hard. Takes a little to get used to adjusting but it's very easy to do.
