Whether you have a stock LS motor or a highly modified LS motor, replacing your rockers with an upgraded trunnion setup is highly recommended. The stock bearings have a tenancy to fail. These rocker arms are a must have for any aggressive heads and cam combo. We utilize LS3 rocker arms and new LS rocker arm bushing style trunnion kit that replaces the cageless, loose OEM needle bearings and powdered metal trunnion with a premium trunnion Kit.
LS BUSHING TRUNNION KITS These new bushing style LS trunnion kits for factory LS rocker arms are now available. The bushing design provides superior lubrication to the trunnion while also providing maximum load capability. Our innovative design prevents premature failures caused by the weak O.E. or replacement needle bearings, eliminating the possibility of debris from a bearing failure that can cause severe engine damage. Our special C932 bushing material is bathed in oil via grooves at 2 different locations on the trunnion. These channels constantly feed oil to the bushing surface ensuring proper lubrication. The greater surface of our bushed trunnion will support 300 times more load than a needle bearing trunnion. Our bushing gets more lubrication and has less load applied to it than the bushing in the small end of a connecting rod, giving it long service life.
Install the upgraded rocker arms to the cylinder heads using the new socket head cap screws supplied. Be sure to rotate the trunnion so that the flat recess side of the trunnion'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.
