CHE Precision has teamed up with some of the industry’s top engine builders to come up with new production replacement LS1, LS2 and LS6 rocker arms. CHE found ways to improve the factory production rocker arms reliability, allowing them to survive the extreme rigors of race engines.
One issue roller rockers inherently have is being prone to failure at high rpm. By replacing the roller bearings assembly with CHE’s proprietary material bushing, this will allow the rocker arm to survive the demands of high rpm.
