Product Features

High-Frequency Induction Hardening The surface is heat-treated to achieve extreme hardness, preventing surface scoring and pitting even under continuous high-load engine operations.
Micro-Finished Lubrication Ports Features precision-drilled oil channels that are micro-polished to ensure a stable oil film, effectively eliminating heat seizure on the rocker arms.
Superior Dimensional Precision Manufactured to exact original tolerances for the 897389-9186, ensuring a perfect 1:1 fit and zero-play installation for the valve train assembly.
Enhanced Fatigue Resistance Constructed from high-carbon alloy steel to withstand constant mechanical shocks and thermal cycles without bending or structural deformation.
Industrial Anti-Rust Protection Coated with a specialized rust-inhibitor oil to maintain pristine surface quality during long-distance transit and long-term warehouse storage.
