Product Details

The Timing Belt is a common part of the engine, but not all OEM and aftermarket timing belts are designed for highly tuned engines. The increased stress load of aggressive camshafts, uprated valve springs, and extreme heat can cause premature wear and failure of the timing belt. The Tomei Powered Strengthened Timing Belt is designed and manufactured with a kevlar fiber (Aramid) belt surface, H-NB rubber, and glass cable core for increased tensile strength and durability. This results in consistent and precise valve timing, ensure engine is operating at optimum, and keep everything in check under extreme conditions.
