Morel T4723 mechanical roller lifters are designed for high-performance engines equipped with solid roller camshafts. Their precision-machined construction and roller design help reduce sliding friction between the camshaft lobes and lifters, supporting consistent valvetrain operation in demanding racing applications.

These lifters are intended for performance engine builds requiring mechanical valve-lash adjustment and properly matched camshafts, valve springs, and pushrods.
