HKS Cam Pulley (EX) - Nissan RB26DETT, RB25DE(T), RB20DE(T)

Pulley is both strong and lightweight.

Using a super light duralumin (A2014) as its main material, the strength and hardness have enhanced by 50% and 30%, respectively (over the previous version). This material improvement enabled a design change that allowed the unit to be significantly lighter (10% less load on RB engines) while simultaneously enhancing engine reliability and power.

Nickel plating improves the anti-friction qualities. 

To withstand stronger timing belts and any foreign items that may get entangled between the gear and belt, the gear section is nickel plated for increased surface hardness (Hv: 350 500 (compared to the prior version).

Cam Sprocket

Controlling valve timing precisely (angle adjustable)The ideal valve timing point will fluctuate when cam duration and other engine characteristics change. As the length of the intake and exhaust cams increases, the overlap levels can be modified for optimum performance. All HKS Camshafts include recommended valve timing, which may be attained by combining these sprockets with HKS camshafts. These sprockets are designed to work with conventional camshafts.
