Truck Performance Pros SuperspringsKIT1 Helper Spring Suspension Kit

The Truck Performance Pros SuperspringsKIT1 is a complete helper spring suspension kit designed to eliminate rear-end sag and stabilize body roll when towing or hauling heavy loads. Built from high-grade shot peened steel, this bolt-on suspension solution works in conjunction with your vehicle's factory leaf springs to provide additional load support without compromising ride quality.

Key Features:

• Self-adjusting design with patented roller shackles that automatically engage as weight is added
• Increases load capacity by 2,000 to 5,000 pounds depending on application
• Reduces rear-end sag, sway, and body roll for improved handling and safety
• Progressive spring rate provides support only when needed, maintaining factory ride quality when unloaded
• Constructed from durable shot peened steel with corrosion-resistant finish
• Complete kit includes mounting hardware and installation components
• Adjustable shackle positions allow customization of preload tension
• No air lines, compressors, or maintenance required

SuperSprings mount directly on top of your existing leaf spring pack and work as a helper spring to support extra weight. The roller technology at each end allows the springs to move smoothly as the factory suspension compresses, eliminating the harsh ride associated with traditional add-a-leaf kits. Ideal for trucks, vans, and SUVs used for towing trailers, hauling cargo, or carrying heavy equipment. Installation typically takes one to two hours with basic hand tools.
