Bronze Bushing kit already installed. These are ready to be bolted on your rectangle port heads
These LS3 Intake Rocker Arms feature offset fulcrum for use on LS3 L99 L76 L77 L92 LS9 LSA L96 "rectangle port" cylinder heads. Include new LS3 specific bolts for installation.
Whether you have a stock or highly modified LS engine, replacing your rockers with a upgraded trunnion setup is highly recommended. The stock bearings have a tenancy to fail, sending loose needle bearings through the engine. 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.
The bushing design provides superior lubrication to the trunnion while also providing maximum load capability. This 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.
Installation:
Be sure to rotate the trunnion so that the flat recessed 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.
