Litens 999360A Automatic Serpentine Belt Tensioner Assembly

The Litens 999360A is an automatic serpentine belt tensioner assembly designed for General Motors applications. Litens was the original equipment supplier of this part and offers this upgraded version for the aftermarket. This tensioner ensures proper belt tension and alignment throughout its service life, maintaining optimal accessory drive performance.

Key Features:

• Upgraded internal "stake" area for improved performance and durability
