Although idler pulleys dont directly spin an accessory, their function in the engine bay is no less vital. When these wear they begin to squeak and squeal which can range from annoying to deafening. Turner Motorsport carries replacement idler pulleys that will eliminate the noise and keep your belts turning smoothly.
Pulleys begin to squeak once they are reaching the end of their life span and if not replaced, can seize up and lead to a long host of problems that would leave you stranded on the side of the road.
