Product Description
LS1 Rocker Arms with Trunion Bearings Professionally Installed
No bolts are included in this kit. You will need to reuse your stock bolts or purchase bolts separately.
Whether you have a stock LS motor or a highly modified LS motor, replacing your rockers with a true roller bearing 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 and are the same rockers we utilize on our 1,000 hp Turbo Motor. The caged roller bearings greatly reduce the possibility of the bearing failure experienced with stock LS1 needle bearings, which can send loose needles throughout the engine upon failure.
Fits the following applications: LS1/LS2/LS6/ LR4 Vortec 5300 LM7 L59 LM4 L33 – 4.8/5.3/5.7/6.0/ Engines.
This kit includes:
16 LS Series Rocker Arms
16 rocker arm trunnions- LS-type retrofit.
32 rocker arm bearings- LS-type retrofit.
32 rocker arm retaining rings- LS-type retrofit.
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 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.
