The HKS VIITS-EG001 is a newly developed reinforced timing belt engineered specifically for the Fiat/Abarth 312A3 engine. Manufactured to strict Japanese quality standards, this belt features an HKS-exclusive design developed by thoroughly analyzing the geometry of the stock belt, cam pulley, and crank pulley to ensure an optimized fit and consistent performance.

Key Features:

• ~1.5x improved performance in heat resistance, tooth jump resistance, tooth wear life, and cut resistance compared to the OEM belt
• HKS-exclusive belt profile developed from full analysis of OEM cam pulley and crank pulley geometry
• New molds and tooling developed to meet Japanese quality manufacturing standards
• Optimized belt design ensures stable meshing and smooth tensioner adjustment during installation
• Distinctive black finish on the back side, printed with the HKS logo, product name, and part number
• Belt Size: 124YS22
• OEM Reference Belt No.: 46403659
• UPC/GTIN: 4957266600894

Precaution: Due to the use of reinforced high-tensile materials, a slight increase in operating resonance may be noticed during normal use. This is expected behavior and does not affect engine performance or belt function.
