Overview
The Daystar KJ02021BK is a greaseable polyurethane shackle bushing kit for leaf spring shackles. It replaces stock rubber shackle bushings. The kit is designed to reduce binding, squeaking and corrosion compared with rubber.
Each kit contains eight fluted bushings, four grade 5 bolts with grease fittings and four locking nuts. The flutes help spread grease across the bushing surface. No specific vehicle is named for this kit.
Key features
- Greaseable design with grease fittings on the included grade 5 bolts
- Fluted polyurethane bushings for even lubrication
- Designed to reduce binding, squeaking and corrosion compared with stock rubber bushings
- Kit includes eight bushings, four bolts and four locking nuts
Shackle geometry and bushing swaps
Shackle geometry affects how the bushings move. As the spring flexes, the shackle swings through an arc, so the bushings twist as well as compress. This is why the fit between the bushing, sleeve and shackle plate matters, and why a loose or mismatched bushing can wear quickly.
When swapping shackle bushings, it helps to inspect the shackle plates and mounting holes first. Worn holes or bent plates will not hold a new bushing properly, and the repair is easier when those parts are checked before assembly. Plan to lubricate the bushings right after installation so the joint is protected from the start.
- Inspect shackle plates and mounting holes first
- Lubricate bushings immediately after installation
- Replace worn bolts when replacing bushings
- Recheck fastener tightness after initial use
