The Litens 999512A Ancillary Drive Belt Auto Tensioner is an OE‑exact replacement manufactured by Litens, the original equipment (OEM) supplier for Nissan. This is the same tensioner design supplied to Nissan for factory installation, offering identical form, fit, and function to the original component.

Designed to automatically maintain correct belt tension throughout its service life, the 999512A compensates for belt stretch and wear while reducing noise, vibration, and belt slip. This makes it the preferred choice for OEM‑level repairs, restorations, and high‑performance applications.
