Tomei Solid Pivot Shim

Nengun Direct Japan introduces the Tomei Solid Pivot Shim. One of the most sufficient ways of making a high performance engine is to install the high lift camshaft. However, in some engines, it cannot be done to raise the lift without applying a smaller base circle of camshaft. Usually, it is dealt with by making special valves or grinding valve sheets or installing thick valve shims, yet, all the above can cause risks of falling reliability of the engine and raising cost of processing. Tomei have designed their own valve lifter, higher than stock so as the high lift camshaft can be installed only by replacing the valve lifter.
