In order to make cam clearance maintenance-free, and achieve operation sound reduction, hydraulic lash adjusters were adopted. However, when aiming at high rotation and a high output by engine modification, it is important to improve the reliability of head parts and to make valve train function correctly. Accordingly, it is necessary to eliminate the function of lash adjuster. Tomei has adopted the solid pivot system to enable cam clearance adjustment, while keeping total height of pivot of each cylinder fixed. Thereby, it is possible to build much precise head system in shorter time compare to the others. Moreover, improvement in reliability and the low price were realized at the same time by having reduced the number of parts.
Features:
Improved Response
With specially designed cam profile characteristics, with the touch of the throttle you will realize the amazing response and improvements in efficiency of ideal valve timing.
Designed for high end RPM use.
The solid conversion will eliminate the dullness experienced at high RPM when using the hydraulic adjustable type.
Special Camshafts and Valve Springs
The solid conversion will also require the appropriate solid type camshafts to be used with the solid pivots. Also since the solid camshafts are designed with higher cam lifts, Tomei valve springs will also be required to provide the adequate clearance and appropriate spring rate (Sold separately).
