Litens 999397A Accessory Drive Belt Tensioner Assembly

The Litens 999397A Accessory Drive Belt Tensioner Assembly is an original equipment quality component engineered to maintain optimal belt tension and alignment throughout its service life. As a leading OE manufacturer, Litens designs this tensioner to meet or exceed original equipment specifications for form, fit, and performance.

Key Features:

• Internal round spring technology provides constant belt tension and compensates for belt stretch and wear
• Heavy-duty steel pulley with close tolerance ball bearing pocket for smooth operation
• Electro-deposited coating provides superior corrosion resistance
• Precision pivot shaft design ensures correct belt alignment
• Application-specific design with tuned tension levels for optimal performance
• Installation instructions included for proper fitment

This automatic tensioner eliminates manual adjustment requirements and extends belt system service life by maintaining consistent tension under all operating conditions. Litens tensioners are designed to handle engine thermal expansion and contraction while dampening vibrations for quiet, reliable operation. Since belt removal is required to change the tensioner, replacing both components simultaneously extends system service life and reduces labor costs.
