The Z17 Stock Replacement kit is PowerStop's straight stock replacement front brake job for the heavy duty GM trucks: Z17 Evolution Plus ceramic pads paired with uncoated Autospecialty rotors that are 100% mill balanced for a smooth, quiet stop. The ceramic compound is a low dust formula validated in third party on-vehicle testing in Los Angeles city traffic, and multi-layer rubberized shims keep braking virtually noise free. Two front sensor wires, stainless steel installation hardware, and high-temperature ceramic brake lubricant come in the box, so the kit goes on as a direct replacement with no modification.
