Product Description

Included: 16 New OEM GM Rocker Arms with Bushing Style Trunnions Professionally Installed and 16 upgraded Allen Head Bolts.
Whether you have a stock or highly modified engine, replacing your rockers with this upgraded Trunnion Kit is highly recommended. The stock bearings have a tenancy to fail, especially with more aggressive than stock camshafts. The Bushings operate smoother and can operate at a higher RPM than the caged bearing style upgrade.
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 a 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 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.
