LS1 Rocker Arms w/ Upgraded Trunnion Installed

LS1 Rocker Arm w/ Upgraded Trunnions Installed

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 caged roller bearings greatly reduce the possibility of the bearing failure experienced with stock LS1 needle bearings.

Stock LS1 Rocker Arm

The stock bearings have a tenancy to fail. 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.
