Product Features
- Forged Alloy Steel with Deep Surface Hardening: Precision-forged from high-grade alloy steel, with cam lobes and journal surfaces subjected to high-frequency induction hardening and fine grinding. This provides exceptional surface hardness and fatigue resistance, preventing pitting, wear, and premature lobe wiping.
- Precise Valve Timing & Optimized Combustion Efficiency: Manufactured with strict adherence to OEM cam profile tolerances and lift specifications, guaranteeing precise intake and exhaust valve timing. This optimizes gas exchange and combustion efficiency, maximizing engine power output while reducing fuel consumption.
- High Load-Bearing Capacity & Outstanding Reliability: Engineered to withstand severe alternating stresses generated by the valvetrain under high-speed, heavy-load conditions. Coupled with precision-machined oil passages, it ensures stable oil film formation between journals and bearings, minimizing friction loss and extending engine overhaul intervals.
