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: Well worth the cost and ease of installation. - 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. ## Features - Genuine (RAS) RoadActive Suspension HD system is designed to strengthen and stabilize rear leaf springs for trucks carrying heavy loads or towing.

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. ### ⭐⭐⭐⭐⭐ Made in the USA quality! *by M***L on July 30, 2024* Arrived quickly and came with a sticker! Installed these on my 05 Silverado 1500HD. They were easy to install in a short amount of time with minimal tools. They lifted the truck a good bit in the rear with them on the 40% setting but not complaining because it sits perfectly level. Unloaded ride quality is great, truck rides smooth and handles well in corners and it has less sway than before. Im excited to see what happens when we load up the camper and the car hauler. ## Frequently Bought Together - (RAS®) RoadActive Suspension 4611-HD | Fits Chevy/GMC 1500 1990-2024 - Fit System 80930 Snap & Zap Custom Fit Towing Mirror for Chevrolet Silverado 1500/GMC Sierra 1500 (2019+), Pair - Camco Tastepure RV Water Filter - New & Advanced RV Inline Water Filter with Flexible Hose Protector - GAC & KDF Filtration - Made in USA - Camping Essentials for Fresh Drinking Water (40043) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/386004503-original-ras-roadactive-suspension-4611-hd-fits-chevy-gmc-1500](https://www.desertcart.tn/products/386004503-original-ras-roadactive-suspension-4611-hd-fits-chevy-gmc-1500) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-25*
