Xray T4 CVD BB driveshaft & gear diff adapter
From Xray for the T4 is this new CVD BB driveshaft 50mm & gear diff adapter. The CVD BB bearing drive shafts improve off-power steering and rotation, but decrease rear traction and stability. Recommended for use in high-traction conditions and for tracks with many hairpin corners. Set includes complete drive shaft only and must be used with optional CNC-machined CVD BB drive shaft adapter made from 7075 aluminium and black coated, it is a direct replacement for the stock version.
