New OEM Genuine Nissan rocker arm for Datsun 240Z, 260Z, 280Z, 280ZX and 510, 1968-1983. This rocker arm will fit L24, L26, and L28 engines. Datsun Z engines require 12 rockers if all are being replaced.
We recommend high zinc (ZDDP) oil for the Datsun "L" series engines and high ZDDP oil is a must with higher than stock valve spring pressures. See PT# 800-1770 for high zinc oil.
*See PT# 800-566 for aftermarket part. See 800-1142X for reground OEM rockers.
