WAI 13961N Alternator Overview

The WAI 13961N alternator is a 136 amp, 100% new charging unit built for Jeep applications that need dependable electrical output. It uses an internal fan, clockwise rotation, a 6-groove serpentine pulley, and an external regulator setup to match the listed OE-style configuration.

Compatible With Jeep TJ, Wrangler, and Liberty applications listed below, this alternator is built on the DENSO family platform and includes a decoupled clutch pulley for smoother belt operation. The WAI 13961N is a direct-fit charging component for vehicles that require the specified amperage and pulley arrangement.
