SuperSprings Leaf Helper Spring Mounting Kit - Installation Hardware

The SuperSprings Leaf Helper Spring Mounting Kit is the required installation hardware for vehicles whose factory leaf springs are positioned above the axle. When factory springs are mounted below the axle, the axle itself naturally acts as a fulcrum for SuperSprings helper springs. For above-axle configurations, these mounting kits supply the critical fulcrum points needed to properly seat, elevate, and anchor the SuperSprings to the top of the factory spring pack — ensuring correct function and long-term durability.

Each kit's primary purpose is to induce a minimal amount of preload tension on the installed SuperSprings. This preload is what keeps the helper springs operating in complete silence when the vehicle is unloaded — no rattles, no movement. Once a load is applied, the roller shackles at the ends of the helper springs pivot and self-adjust, smoothly transferring weight through the suspension system.

Key Features:

• Required for vehicles with factory leaf springs positioned above the axle
• Mounting brackets serve as fulcrum points on the underside of the SuperSprings
• Elevates, insulates, and anchors SuperSprings securely to the factory spring pack assembly
• Induces minimal preload tension for silent, rattle-free operation when unloaded
• Includes U-bolts, cross plates, washers, hold-down clamps, and Nylok self-locking nuts
• Nylok nuts resist loosening from vibration and repeated load cycling
• Sold as a pair (left and right side)
• Maintenance-free construction — proudly made in the U.S.A.
• Multiple configurations available to accommodate different spring pack heights and installation requirements

Multiple kit variants are available across this product line to accommodate a range of spring pack heights and vehicle configurations. These mounting kits are a necessary complement to the SuperSprings helper spring system for above-axle leaf spring setups, delivering a secure, noise-free installation that protects your suspension investment for the long haul.
