Racers wanting predictable front behaviour on varied surfaces will find the XRAY 335000 Front Gear Differential Set a useful upgrade for the NT1. The full kit includes a composite case, cover and a 27T pulley to refine the front driveline.
The gearbox uses pressed steel gears that are heat treated and machined to produce close tolerances and consistent engagement. This approach balances strength with smoothness under load.
The supplied CNC-machined diff outdrive adaptors are manufactured from HUDY Spring Steel and are paired with polished, precision-ground shafts to cut friction and improve rotation consistency. These parts contribute to a controllable front diff feel.
Since the differential comes as a kit, you can set up shimming, preload and lubrication to suit driving style and surface grip. Keep parts clean and use the correct diff fluids to maximise life and performance.
