【Why need a Replacement?】 Opening and closing your car's valves will suffer when a rocker arm is broken or loose. You will notice a drop in engine power and a drop in acceleration, at this time we recommend that you replace it with a new replacement
【Notes】 the upgraded rocker arms to the cylinder heads using the new socket head cap screws supplied. Be sure to rotate the trunion so that the flat recess side of the trunion's center hole faces upward (the socket head cap screw must seat against this recessed flat side of the hole). Tighten the cap screw to a value of 22 ft-lbs, following the OE installation procedure.
