SumoSprings SSR Rear Air Helper Springs SSR-290-54 for Chevrolet P30, Workhorse P30, P32

The SumoSprings SSR Rear Air Helper Springs SSR-290-54 are advanced suspension enhancements designed to replace or upgrade factory rear bump stops. Unlike traditional air bags, these are manufactured from proprietary closed micro-cellular urethane, which provides a progressive spring rate. This design ensures that the springs remain soft during initial engagement for comfort but become increasingly firm as the load increases, effectively reducing rear-end sag, body roll, and waddle.

As a "fit-it-and-forget-it" solution, these rear helper springs require no air lines, no compressors, and no maintenance. They are engineered to work independently, allowing each side of the vehicle to react to off-center loads or sharp turns. This makes them ideal for trucks, vans, and motorhomes that frequently tow trailers or carry heavy payloads.

Features of SumoSprings SSR Rear Helper Springs:

• Micro-Cellular Urethane Technology: Utilizes millions of microscopic air bubbles to provide superior damping and a smooth, progressive spring rate.
• Maintenance-Free Design: Eliminates the risk of leaks and the need for air pressure monitoring, as there are no internal air bladders or hoses.
• High Compression Capacity: Capable of compressing up to 80% of its original height while maintaining full memory rebound.
• Progressive Load Control: Automatically adjusts its resistance based on the weight of the cargo, providing more support as the vehicle is loaded.
• Durable and Resilient: Highly resistant to oil, road salt, and UV rays, with a functional temperature range from -25°F to 200°F.
• Straightforward Installation: Most kits feature a no-drill, bolt-on installation that utilizes existing factory mounting holes and hardware.

Benefits of SumoSprings SSR Rear Helper Springs:

• Eliminates Rear-End Sag: Provides significant load support (ranging from 1,000 lbs to over 5,000 lbs at 50% compression) to keep the vehicle level while hauling.
• Reduces Sway and Body Roll: Improves stability by absorbing lateral movement, which is critical for high-profile vehicles and towing setups.
• Enhanced Driver Comfort: Dampens road vibrations and harsh impacts, preventing the "bottoming out" feeling often experienced with factory bump stops.
• Improved Safety in Crosswinds: Keeps the vehicle tracking straight by minimizing the impact of wind gusts and the air wake from passing vehicles.
• Preserves Factory Suspension: Reduces the stress on factory leaf springs and shocks, helping to extend their overall service life.
