Hot Cams 07-16 CRF 150 R/2016 CRF 150 RB Big Wheel 1.400mm Shim Kit - 5 Pack

Hot Cams is known for making performance valvetrain components. This shim kit is designed for engine valve adjustments, helping you get the right clearance for optimal performance. Each shim is made from 4140 cold rolled steel, a material chosen for its high strength and consistent hardness, which is important for maintaining precise valve lash over time.

This particular kit includes 5 shims, each measuring 1.400mm. Using the correct size shims ensures your engine's valves open and close at the precise moments needed for efficient combustion and power delivery. The uniformity of hardness in the 4140 steel means these shims will hold their shape and size under the heat and pressure of engine operation, contributing to reliable performance.
