Supertech Cam Follower 35mm x 25mm x 2.7mm - Set of 8

These Supertech cam followers measure 35mm in diameter, 25mm in length, with a 2.7mm thickness. They are sold as a set of eight, which is typically what you'd need for a 4-cylinder engine. Cam followers, also known as lifters or tappets, are crucial components that sit between the camshaft lobe and the valve stem. They translate the rotating motion of the camshaft into the linear motion needed to open the engine's valves, ensuring proper timing and airflow.

Constructed from well-built materials, these followers are designed to withstand the high-speed, high-pressure environment of your engine's valvetrain. The precise dimensions ensure they fit correctly within the cylinder head and maintain proper valve lash, which is the small gap that allows for thermal expansion. Maintaining the correct valve lash is important for engine performance and longevity, preventing issues like burnt valves or excessive valvetrain noise.

When rebuilding or servicing your engine's top end, using precise, well-made components like these Supertech cam followers is essential for reliable operation. They are a solid option for anyone looking to replace worn parts or ensure their valvetrain is functioning as intended.
