Hot Cams Shim Kits 3.100mm Thickness - 5 Pack

This is a Hot Cams Shim Kit, specifically the 3.100mm thickness, 5-pack version. These small but crucial parts are used in your engine's valve train to set the correct clearance between the camshaft and the valve bucket or rocker arm. Getting this clearance just right is important for proper engine operation, performance, and longevity.

Each shim in this kit is made from 4140 cold rolled steel. This material is chosen for its high strength and consistent hardness, which means these shims will hold their size and shape under the heat and pressure inside your engine. They're also priced competitively compared to original equipment manufacturer parts, making them a smart choice when you need to replace or adjust your valve clearances.
