Pulley & Belts

Find New OEM serpentine belts and idler pulleys for GM vehicles. Our factory-original belts and pulleys are sourced from GM surplus — the correct belt length, rib count, and pulley diameter for your engine's accessory drive system.

Idler pulley bearing failure is a leading cause of serpentine belt failure and accessory drive noise. OEM idler pulleys use bearings rated for the temperature and load cycles of your engine compartment — providing the service life and smooth operation that your tensioner and belt system require.

Replace the belt, tensioner, and all idler pulleys together for a complete accessory drive service. Verify part numbers against your engine's belt routing diagram and RPO code before ordering.
