SuperSprings Leaf Spring Enhancer SSA9 for Chevrolet Express 2500, 3500, GMC Savana 2500, 3500

The SuperSprings Leaf Spring Enhancer SSA9 is a unique, "tension-style" helper spring designed to eliminate rear-end sag and reduce body roll in vehicles with leaf spring suspensions. Unlike traditional helper springs that sit on top of the axle, SuperSprings feature a patented roller-bolt design that allows the helper to remain inactive when the vehicle is unloaded, maintaining the factory ride quality. As weight is added, the rollers engage, providing immediate tension and support.

These enhancers are specifically engineered for work trucks, delivery vans, and motorhomes that frequently haul heavy equipment or tow trailers. By reinforcing the existing leaf pack, they prevent the springs from becoming over-compressed, which restores proper ride height and ensures safer, more predictable handling under load.

Features of the SuperSprings Leaf Spring Enhancer:

• Patented Roller-Bolt Design: Automatically activates only when the load requires it, ensuring a comfortable ride when the vehicle is empty.
• High-Grade 5160H Steel: Manufactured from the same high-tensile shot-peened steel used in heavy-duty racing and commercial springs for maximum durability.
• Progressive Tension: Provides more support as the load increases, effectively leveling the vehicle and reducing "bottoming out."
• Self-Adjusting Fit: The rolling shackles allow the spring to move freely, preventing the stiff, jarring ride associated with static helper springs.
• Bolt-On Installation: Designed to install over the top of the factory leaf spring pack using standard hand tools, with no drilling or welding required.

• Eliminates Rear-End Sag: Levels the vehicle to ensure proper headlight aim, steering geometry, and braking performance when fully loaded.
• Reduces Body Roll and Sway: Dramatically increases stability by up to 30%, making it much easier to control top-heavy vans and RVs in corners or crosswinds.
• Maintenance-Free Performance: Unlike air bags, these steel springs cannot leak or fail and require no air lines or pressure monitoring.
• Extended Suspension Life: Reduces the stress on factory leaf springs and shocks, helping to prevent premature sagging and component failure.
• Increased Driver Confidence: Provides a firm, planted feel that eliminates the "floaty" sensation often felt when towing or hauling heavy payloads.
