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!
