SUPERSPRINGS SumoSprings SSR-217-47 Rear Suspension Helper Springs for 2019-2020 GM Full-Size Trucks

Upgrade the rear suspension of your 2019-2020 GM full-size truck with the SUPERSPRINGS SumoSprings SSR-217-47 rear suspension helper spring kit. Designed as an OEM-style bump stop replacement, this bolt-on pair helps support up to 1,500 pounds of additional load capacity while improving suspension stability, ride control, and load-carrying performance. The kit is engineered specifically for compatible GM full-size truck applications and provides a straightforward installation using the included hardware.
Each SumoSpring is molded from durable polyurethane and finished in black for long-lasting performance and a clean, factory-inspired appearance. The progressive spring design is intended to engage as the vehicle is loaded, helping reduce rear-end sag, body roll, sway, and suspension bottoming without requiring air lines, compressors, or ongoing air-pressure adjustments. This makes the SSR-217-47 a practical choice for towing, hauling, work use, and everyday driving where additional rear suspension support is needed.
The SUPERSPRINGS SSR-217-47 kit includes two rear helper springs and installation hardware for a complete bolt-on upgrade. Its OEM-style configuration is designed to work with the original suspension layout while preserving a controlled, comfortable ride when the truck is unloaded. Confirm vehicle compatibility before ordering to ensure proper fitment for your specific GM full-size truck. This product is supplied as a pair and is not restricted to air-based installation systems.
