GM LS Rocker Arms Set with Upgraded Trunion Bearings Installed
Our high quality steel alloy LS rocker arms feature caged roller bearings and 8620 steel trunions for superior durability and performance over the stock units. Engineered to handle higher spring pressures and high engine RPM’s. 100% drop-in design that meets or exceeds OEM specifications for a hassle free installation. 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.
