Product Features

Extreme Thermal Resilience Forged from specialized heat-resistant alloy to maintain structural geometry and prevent cracking under intense 6HK1 exhaust stroke temperatures.
Induction-Hardened Wear Zones Contact surfaces are hardened to HRC 58-62, effectively eliminating surface pitting and stem wear to maximize the overall valve train service life.
Precision-Engineered Oil Flow Micro-polished internal lubrication galleries ensure a constant oil film on the rocker shaft, preventing heat seizure and reducing frictional loss.
Seamless 1:1 OEM Interchangeability Manufactured to exact 8943929936 specifications to ensure perfect timing synchronization and a fast, error-free installation process for ZX330 fleets.
High-Cycle Fatigue Resistance Advanced metallurgical properties allow the component to endure millions of high-pressure cycles without deformation in 24/7 industrial applications.
