The SuperSprings SSA52 Rear Leaf Helper Spring Kit is designed to provide additional rear suspension support for 2019-2025 Silverado and Sierra 4500HD, 5500HD, and 6500HD trucks. Engineered to work with the factory leaf spring system, this helper spring kit supports the rear suspension when the vehicle is carrying cargo, transporting equipment, or operating with heavier loads. The helper spring engages as additional weight is applied to the rear suspension. As the factory leaf springs compress under load, the helper spring provides added support to help maintain a more consistent ride height and vehicle stance. This design helps distribute weight more evenly across the suspension system and supports balanced handling during hauling and towing applications. Constructed from durable steel components, the SSA52 helper spring kit is designed for trucks used in commercial, fleet, and heavy duty work environments. The system works alongside the existing leaf springs and does not require major modifications to the suspension system. Installation is designed to integrate with the factory suspension using existing mounting locations. Once installed, the helper spring automatically responds to changing loads without the need for manual adjustments or ongoing maintenance. With a load support capacity of up to 3400 pounds, the SuperSprings SSA52 Rear Leaf Helper Spring Kit provides additional rear suspension support for Silverado and Sierra 4500HD, 5500HD, and 6500HD trucks while maintaining compatibility with the original suspension configuration.
- Vehicle Compatibility: These SuperSprings are specifically designed to fit 2019-2025 Silverado 4500HD/5500HD/6500HD & 2019-2025 Sierra 4500HD/5500HD/6500HD; Fits both 4x2 & 4x4 models
- Heavy-Duty Load Leveling: Adds up to 3,400 lbs of additional load-leveling capacity to your vehicle’s rear suspension. Ideal for chassis cabs, utility trucks, and heavy-duty haulers frequently carrying tools or gear
- Zero Maintenance: A true "fit and forget" solution. Unlike air bags, there are no air lines, no compressors, and no leaks to worry about. Installation is bolt-on and typically takes less than one hour with no drilling required
- Enhanced Stability & Safety: Significantly reduces body roll by up to 30% without stiffening the ride. This stabilizing effect improves driver control in crosswinds and sharp turns while towing or hauling top-heavy loads
