We do not trust ebay cam gears made of softer metal that tends to warp and break. Timing is critical for tuned engines, especially with performance camshafts. These are HKS genuine parts are top-of-the-line 4AGE 16V performance parts and are designed with meticulous attention to detail. These adjustable cam pulleys utilize ultralight duralumin as the primary material, and nickel plating boosts its anti-frictional properties. HKS Adjustable Cam Gears allow variable tuning of the camshaft timing to maximize compression, porting, custom camshaft grind profiles and to tune your powerband for various driving conditions. Whether you’re on the road or at the track, you’re going to have a better driving experience. With either OEM or HKS Camshafts, adjustments can be made to tune an engine.

HKS SLIDE CAM-PULLEY
Reviewing the material and design has allowed for a stronger and lighter unit.
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.
