KS Fine Tune Timing Belt – Subaru WRX, STI, Forester XT, Liberty GT (EJ20/EJ25)
Designed for high-performance engines, the HKS Fine Tune Timing Belt is ideal for Subaru EJ20 and EJ25 engines found in WRX, STI, Forester XT, and Liberty GT models. Engineered to work seamlessly with HKS Slide Cam-Pulleys, this reinforced timing belt ensures optimal performance in high-revving and high-output applications.
Key Features
- Optimised belt strength tailored for EJ20 and EJ25 engine platforms
- Maintains stable belt tension even with thermal expansion under high-RPM conditions
- Moulded tooth design increases strength and reduces risk of belt skipping under torque load
- Constructed from H-NBR grade rubber for exceptional durability and heat resistance
- Perfect match for HKS Slide Cam-Pulleys in tuned and built engines
Why Choose the HKS Fine Tune Timing Belt?
Unlike conventional belts that use pressure-formed teeth, the Fine Tune belt utilises a precision-moulded design that maintains structural integrity without sacrificing tooth strength. This ensures more reliable valve timing control under extreme conditions, particularly in turbocharged EJ engines operating at high load and RPM.
