Professionally Reconditioned with Premium Components
Every Nissan Patrol 4.6 differential centre undergoes an exhaustive workshop overhaul. The housing and carrier assembly are stripped down, thoroughly cleaned, and evaluated for case distortion and wear. We rebuild these units using premium Japanese bearings and seals, setting ring-and-pinion backlash, bearing preloads, and tooth contact patterns to exact factory specifications. Quality genuine and aftermarket components are used throughout to ensure optimal strength and quiet operation under heavy towing or off-road conditions.
Why Choose a 4.6 Ratio Differential Centre?
The 4.625:1 ratio (factory code HG46) is a popular choice for Nissan Patrol owners running larger tires (such as 33-inch or 35-inch setups) or seeking to recover lost engine torque and crawl ratio. Fitting a factory-spec reconditioned differential centre provides a far more dependable, long-term solution than taking a gamble on an untested second-hand unit.
