Precise nylon pulley (34T) and Labyrinth Dust Covers for ball-differential.

The pulley features XRAY invented and patented "Labyrinth Dust Covers", special anti-dust protective covers that are great for keeping dust and dirt out of the diff. Each pulley uses 12 diff balls. 

Two diff washers for ball-differentials. Each side of the washer has a distinct finish; a polished side against which the diff balls ride, and a rougher machined side that contacts the duraluminum diff output. Specially hardened to assure maximum life.  

Carbide balls 2.4mm for ball differential. Improved, smoother diff operation over standard steel diff balls.  

High-precision axial thrustbearing 3x8x3.5mm for ball differential features Tungsten Carbide balls.  

High-quality ball-bearings ID x OD x thickness (mm) = 5x8x2.5mm. Set of 2 pieces. 

Cone washer ID x OD x thickness = 3mm x 8mm x 0.5mm. Set of 10 pieces.  

8mm CH-clip. To ensure smoother, more precise operation of the XB2 and XB4 differential, the CH clips used inside the differential are manually ground. Set of 2.
