Roller Pin & Circlip Kit

The Roller Pin & Circlip Kit is an essential replacement hardware set designed for use with Yella Terra rocker arm assemblies. It is ideal for both automotive enthusiasts and professional engine builders who require reliable components for their valvetrain systems. This kit helps ensure that the roller bearing within the rocker arm is securely positioned, which is crucial for maintaining engine performance during high-RPM operation.

Engineered to withstand extreme thermal and mechanical stresses, the Roller Pin & Circlip Kit is made from durable steel. The precision-machined roller pin provides a smooth surface for the bearing rollers, while the included snap rings ensure positive retention within the rocker body. This design minimizes friction and promotes consistent valve lift across the powerband.

This kit is particularly beneficial for those performing routine maintenance or rebuilding a valvetrain, as it helps maintain factory-level tolerances in aftermarket rocker setups. Its compact dimensions and lightweight profile ensure that it does not add unnecessary reciprocating mass to the assembly, making it a vital component for optimal engine performance.
