Kevlar non-Greasable Rear Spring Bushing Kit, 43mm Spring Eyes

These kits consist of grooved Kevlar bushings, grade 8 bolts, and  DOM steel sleeves.  Each kit replaces the bushings/sleeves/bolts at both ends of both springs.

If you don't know what your inside diameter eye size is here is a quick way to find out.

Measure the Outside diameter of the spring eye, then measure the thickness of the main leaf. 

Subtract 2x's the thickness of the leaf from the outside diameter. That should result in your inside diameter. 

We've implemented new Kevlar infused polyurethane bushings into our entire lineup, any of our products with suspension bushings in them will now have the best bushings available!

Infusing Kevlar into polyurethane doubles the tensile strength, tear resistance, and increases the life of the part by cross linking the polyurethane. We elected to keep the same durometer (stiffness) so as not to inhibit suspension travel, as well as keeping the black color everyone is used to. Basically with double the tensile strength, the bushing can be pushed harder and still come back to it's original shape. All of that means using your truck more and maintaining it less, and reduces the cost of replacing bushings!

Due to its wide range of elastomeric properties and strength factors, Kevlar Infused polyurethane out handles, out preforms, and outlasts other similar polyurethane materials on the market.

We also added chamfers to make bushing install easier!
