Product Description

The Whiteline W73821 kit is a comprehensive leaf-spring bushing service set designed for Chevy and GMC trucks - covering the front eye, rear eye, and shackles of leaf springs. Over time, the OEM rubber bushings wear out, leading to loose or sloppy spring mounting, which can compromise handling, ride quality, and stability under load. This upgrade replaces all those critical bushings with durable polyurethane, restoring tightness and improving rear suspension control.

Built for high mileage, towing, and heavy-duty use, this kit's high-load design resists abrasion and environmental damage, making it well suited for trucks that carry weight or cover a lot of ground. The polyurethane formulation resists oil, grease, ozone, and weathering, helping the bushings last longer than stock rubber. With a roughly 2-hour install time and covered by Whiteline's limited lifetime warranty, W73821 is a reliable choice for anyone looking to refresh or upgrade their leaf-spring mounting system.
