GM OEM Belt Tensioners are built to rigid tolerances and specifications that guarantee OE fit, form and function.
Patented vibration damping system improves tensioners, belts and accessory life.
Round Torsional Spring design provides:
Tighter dimensional tolerances for better output control.
No heat build up, leading to longer tension life.
Even rotational load, offering resistance to compressive force.
Dampening mechanism absorbs shock loads for stable operation
