The timing belt performs the critical role of synchronizing the various rotating assembles in your engine, such as the camshaft(s) and crankshaft, so to ensure the precise timing and efficient operation of the engine cycles, while keeping your cylinder and valves from colliding and causing catastrophic engine failure.

GMB timing belt kits incorporate the timing belt, tensioner and idler where relevant so to allow you to replace all the linked components in one fell swoop, minimising labour costs and ensuring the safe running and efficiency of your engine is maintained between major service intervals.
