Product Description

The Gates T1040RB Racing Timing Belt is a high-performance, reinforced timing belt engineered for turbocharged and high-RPM engines requiring robust cam/crank synchronization. Built from HNBR rubber with fiberglass tensile cords, it offers enhanced resistance to heat, oil, and engine fluids - making it suitable for demanding conditions and performance-tuned engines.

With 141 teeth, a standard 8 mm tooth pitch and a 25.4 mm width, this belt is designed to match the camshaft and crankshaft pulley configurations common in RB-series engines from Nissan's Skyline lineup. Its reinforced construction and precise tooth profile help maintain timing accuracy and minimize risk of slippage or tooth jump under high load or high RPM - critical for interference engines.
