Professionally Reconditioned with Premium Components
Every Nissan Patrol 3.9 rear diff centre undergoes a rigorous workshop overhaul. The assembly is completely stripped, hot-washed, and inspected. Rebuilt using premium Japanese bearings and seals, genuine components where required, and expertly fitted with the Harrop eLocker unit, each diff centre undergoes strict setup procedures. Pinion bearing preloads, crown wheel backlash, and tooth contact patterns are set to exact factory specifications for whisper-quiet running and maximum strength under heavy off-road use.
Why Upgrade to a Rear eLocker Differential Centre?
High-kilometre Patrols frequently suffer from worn or broken LSD clutch packs, bearing wear, and excessive ring-and-pinion slop. Upgrading to a pre-built 3.9 ratio eLocker unit eliminates slip entirely when engaged, delivering equal torque to both rear wheels without requiring air lines, compressors, or complex pneumatic maintenance.
