When installing cams and/or camgears, its a good idea to replace your timing belt at the same time as your current timing belt will need to be removed anyways to install the parts. Timing belts do not last forever and old factory belts can become dry rotted or weakened.
This timing belts best suited for use with HKS Slide Cam-Pulley. Optimised belt strength for each engine application makes the Fine Tune Timing Belt ideal for use with HKS Slide Cam-Pulleys for high power/high RPM engine.

• Belt strength has been optimized for each engine application and designed to allow stable belt tension even when heat expansion occurs in the engine
• Previous timing belt manufacturing techniques have involved with applying pressure from the outside to the teeth. This applies tension to teeth making them weaker. By forming a mould with the correct shape of teeth to begin with, will allow the teeth shape to be formed without compromising belt strength and can decrease the belt skipping at high torque engine.
• Teeth rubber is made from H-NBR grade rubber for additional strength.
