HKS Fine Tune Timing Belt - RB20 RB25 RB26

HKS 24999-AN001 Fine Tune Timing Belt - RB20 RB25 RB26   This is a high strength timing belt replacement that will hold up to the task. With increased heat-resistance, durability, and flexibility.    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 mold 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.    * Necessity of Changing Balancer Belt  The balancer is designed to reduce engine vibration by creating a vibration in the opposite direction to the engine. When used at high RPM such as on circuits, the vibration
