KellTrac Front Coilover Bushing Replacement Kit, Hybrid, Full Set (KTI-BUK58-125-4) - 2015–2026 Ford F-150
The KellTrac Hybrid Front Coilover Bushing Replacement Kit is designed as a direct upgrade for Viking coilovers installed on 2015–2026 Ford F-150 trucks. This kit replaces worn or deflective factory-style bushings with a hybrid solution that combines precision spherical bearings with polyurethane isolation—delivering improved suspension control while managing NVH for street and race-driven trucks.
Engineered for coilover systems using a 1.25-inch wide mounting point, this kit is compatible with KellTrac, UMI, VAS, 2MFab, and similar front coilover conversion mounts. By eliminating excessive deflection at the coilover mounting points, this upgrade allows the shock to react more accurately to suspension movement, improving traction, consistency, and front-end stability.
Designed as a complete solution for a full pair of front coilovers, this kit includes all required bearings, sleeves, snap rings, and protective polyurethane outer bushings to ensure a precise, long-lasting installation.
Kit Includes
- (4) 5/8-inch Teflon-lined stainless steel spherical bearings
- (4) Zinc-coated 5/8-inch to 1/2-inch reducer sleeves
- (8) Retaining snap rings for secure bearing installation
- (8) Polyurethane outer bearing protector bushings
