    The R3070 trunion upgrade rocker arms are a direct-fit replacement for the factory rocker arms. The trunions are made of 8620 steel alloy and have fully caged roller bearings. The upgrade allows the engine to handle higher spring pressures and higher RPMs than before without the need for taller valve covers.

    Applications:

    • LS1, LS2, LS6
    • LR4, LM7, L59, LM4, L33 Vortec 4.8L/5.3L/5.7L/6.0L

    Notes:

    • Rotate trunion so the flat recess faces up
    • The torque specification for the rocker bolts is 22 ft.-lbs.
