Description

Manufacturer Part Number: 22004-AM001

Ideal upgrade for the 4G63 Engine.


HKS adjustable Cam Gears allow fine tuning of the camshaft timing to maximize engine performance and tailor power characteristics for various driving conditions.

Either with OEM or HKS Camshafts, adjustments can be made to tune an engines power band to optimum RPM range for a particular application. HKS Cam gears are made completely of anodised duralumin with nickel plated gear teeth except for applications with timing chains which utilise an aluminium slide with steel teeth. HKS engineers chose duralumin as the core material for HKS Cam Gears because its lightweight properties decrease drag on the engine.

Precise Valve timing can be adjusted and set at intervals. Each Interval index is laser-etched into the duralumin and ‘A’ (advance) and ‘R’ ( retard) directional markers are also laser etched onto the cam gear face.

Highly durable and lightweight pulley

  • Using a super light duralumin (A2014) as its main material that the strength has increased by 50% and hardness by 30% (over previous version). This change in material has allowed the design change that has also allowed the unit to be substantially lighter (10% less load on RB engines) and increasing the engine reliability and power.

Nickel plating increases anti-frictional properties

  • Gear section is nickel plated for surface hardness increase (Hv: 350 → 500 (compared to older version)) to withstand strengthened timing belts and any foreign objects that may get caught between the gear and belt.

Quantity of 2 x is required per vehicle. Same pulley used for Intake and Exhaust
