The Tappet has a tough job, and eventually the case hardened tip will wear through, and the valves will no longer open correctly for optimum performance.Helps ensure valves open and shut smoothly. Worn tappets mean reduced performance and a noisy top end rattle.
If you are already replacing your camshaft and/or push-rods, then we do recommend new tappets as a matter of course.

It is always worth checking carefully that the part number you specify is compatible with your model before placing you order, this helps avoid the frustration of ordering an incorrect part!
