Spring Bushing Kit Chevrolet C10 75-86

The Spring Bushing Kit Chevrolet C10 75-86 is a rear leaf spring and shackle bushing replacement designed for serious truck owners who demand improved suspension geometry and reduced chassis flex. If you've noticed excessive play in your C10's rear end during acceleration, braking, or cornering, worn factory rubber bushings are likely the culprit. This Whiteline Performance kit eliminates that slop, restoring precise suspension kinematics and dramatically improving handling response on both street and light off-road duty.

Constructed from high-durometer polyurethane paired with zinc-plated steel components, the Spring Bushing Kit delivers superior durability compared to factory rubber while maintaining drivability. Polyurethane bushings resist oil degradation, UV damage, and thermal cycling—factors that cause stock rubber to harden, crack, and fail prematurely. The zinc plating on steel hardware prevents corrosion, ensuring long-term reliability. Installation involves removing the rear leaf spring assembly and pressing out worn bushings, then installing the new kit. Whiteline's engineering ensures proper spring geometry is maintained, preventing ride height changes or binding issues.

This kit is essential for 1975–1986 Chevrolet C10 full-size truck owners undertaking frame-off restorations, suspension upgrades, or addressing worn rear-end symptoms. Whether you're building a daily driver, weekend hauler, or vintage truck project, upgrading to polyurethane bushings eliminates a common wear point and improves long-term reliability. The compact kit (7.55 x 3.75 x 7.85 inches, 2.09 lbs) ships ready to install—no modification or fitment issues. Pair this with other Whiteline suspension components for a complete chassis upgrade that transforms how your C10 responds to the road.
