Fitment Notes

Rear leaf spring, rearward eye position
One source also lists this bushing for the Hummer H3 - the H3 rides on a different platform (GMT355) than the Silverado/Sierra 1500 (GMT800/GMT900/K2XX), so this may reflect a shared leaf spring bushing dimension rather than a shared chassis. I couldn't confirm the H3 application against a second source, so treat that fitment as unverified until checked directly with SuperPro if you're working on an H3
Often installed alongside SPF5588K (rear upper leaf spring shackle bushing) as part of a complete rear leaf spring bushing kit, or as part of SuperPro's larger front-and-rear master kit (KIT248K) for these trucks

Product Description

The rearward eye of the rear leaf spring is a high-load pivot point that takes on constant flex every time the truck's rear suspension moves - whether that's from everyday road imperfections, hauling cargo, or towing. Factory rubber bushings here wear out relatively quickly under that kind of repeated load, leading to excessive movement, clunking noise, and suspension play that compounds wear on other rear-end components over time.

SuperPro's SPF5587K replaces this wear point with a polyurethane bushing engineered for long service life under load, using integrated grease retention and a durometer chosen specifically to balance durability with quiet operation. It spans multiple generations of GM's full-size truck platform, from the classic-body 1999-era Silverado/Sierra through the K2XX-generation trucks built through 2021.

This kit suits Silverado and Sierra 1500 owners who tow, haul, or have simply put enough miles on the truck to feel play developing in the rear suspension. It's commonly paired with the corresponding shackle bushing (SPF5588K) for a full rear leaf spring bushing refresh, or bought as part of SuperPro's larger front-and-rear master bushing kit for a complete suspension overhaul in one purchase.
