Supertech Cam Follower 31mm x 25.5mm x 2.5 - Set of 12 (Use w/8mm Dia Shim)

These Supertech cam followers measure 31mm in diameter and 25.5mm in length, with a 2.5mm thickness. They are designed to work with 8mm diameter shims, which are crucial for setting your engine's valve lash. When rebuilding or modifying an engine, especially if you're working on the valvetrain, precise control over valve lift and timing is key to performance and reliability. These followers are a well-built component for that purpose.

The followers are constructed from hardened steel, a material chosen for its durability under the high stresses of engine operation. This hardened steel construction helps resist wear in the contact area where the camshaft lobe meets the follower, ensuring consistent performance over time. Having a full set of 12 means you have what you need for most 4-cylinder or 6-cylinder engines where each cylinder has two valves, or for engines with specific valvetrain configurations. Proper installation and ensuring the correct shim size are critical for optimal function.
