Product Description

The SuperPro SPF4571K Rear Spring Eye Bush Kit is designed to rejuvenate the rear leaf-spring mounting integrity on Chevrolet Silverado and GMC Sierra heavy-duty trucks (2500/3500 series) from model years 2007-2014. Over time, factory rubber bushes in the leaf-spring eye mount positions can deteriorate, leading to excessive movement in the rear suspension assembly, alignment drift under load, and premature tyre wear. This kit replaces those worn components with premium polyurethane bushings, restoring firm spring eye mounting and improved chassis response under towing or high-load conditions.

Recognising the rigours of heavy-duty truck use, this kit leverages SuperPro's long-life polyurethane compound to deliver greater durability and consistent performance compared to standard rubber parts. Installation is made easier by direct-fit design into the original mounting points. After fitting both sides, a full rear wheel alignment is strongly recommended to ensure optimal geometry and maximise the benefits of the upgrade. Whether you tow heavy loads, use the truck in commercial service, or simply want to restore ride and handling precision, this kit offers a high-quality solution.
