HKS Fine Tune Timing Belt - 2002-2014 WRX / 2004-2021 STI / 2005-2012 LGT / 2004-2013 FXT / 2005-2009 Outback XT

The HKS Fine Tune Timing Belt is made for high power/high RPM Subaru engines. Belt strength has been optimized and designed to allow stable belt tension even when heat expansion occurs in the engine.

Previous timing belt manufacturing techniques have involved 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, it allows the teeth shape to be formed without compromising belt strength and can decrease the belt skipping on a high torque engine.

The teeth are made from H-NBR grade rubber for additional strength.

Features:

- Made using durable materials

- Designed to be heat resistant

- Has more flexibility and durability when compared to OEM

- Reduced cracking and premature wear on engines that have been built to exceed factory horsepower limits
