Manley pistons for the 4G63 are machined of high strength 2618 material. Each design is lightweight yet robust enough to deliver long service life. Round wire locks, tool steel wrist pins, and rings are included with every set at no additional charge. A proprietary multi-step top ring groove machining process assures optimum control of the groove's size, geometry, flatness and finish. Precise pinhole machining results in an exact compression distance as well as precise lock ring groove spacing, size and concentricity.
Note:Be sure you know wether you have a 6 bolt or a 7 bolt 4G63 before ordering.
