UPGRADED BOLTBased on user experience, we have improved the quality of the bolts. The new version matches the original size, offers higher strength, is more resistant to loosening and shocks. We use steel material to prevent stripping and ensure better durability, addressing concerns raised about aluminum bolts
FUNCTIONThe serpentine belt can transmit power to the engine accessories, and the tensioner can provide the necessary belt tension for the system, control vibration, reduce noise and extend the belt life. The idler pulley can help improve drivetrain stability. If a car does not have a good tensioner, idler pulley and belt kit, then no matter how powerful the engine or the fast tires it is, it will be useless
