Professionally Reconditioned with Premium Components
Every Nissan Patrol 4.1 rear differential centre undergoes an exhaustive workshop overhaul. The housing is completely stripped, hot-washed, and evaluated for case distortion and wear. We rebuild these assemblies using top-tier Japanese bearings and seals, genuine components where required, and quality replacement gearsets. The Harrop eLocker unit is installed with exact precision, setting ring-and-pinion backlash, bearing preloads, and tooth contact patterns to strict factory specifications for quiet operation and long-term durability under extreme loads.
Why Upgrade to a Pre-Built eLocker Differential Centre?
Factory Patrol rear diffs—especially high-kilometre LSDs—frequently suffer from worn or broken clutch packs, pinion bearing whine, and excessive drivetrain slop. Buying a fully assembled reconditioned diff centre with an eLocker pre-installed eliminates all the setup labor. Electromagnetic actuation means no air lines, zero pneumatic maintenance, and seamless selectable 4WD performance whenever you need it.
