KR CNC Main Shaft V2 POLYGON BFA/M244 Black-Edition

Suitable for both internal and external oil seals, this drive shaft is designed for rear wheel torques exceeding 500 Nm, specifically for high-performance BFA's and M244. Nevertheless, it is important to ensure that the damper can withstand the applied torque. The increase in strength was achieved by enlarging the bearing journal to 25mm.

The complete set, as shown in the pictures, is supplied.

The steel ring is placed under the bearing, then the bearing is installed in the engine block. The rear wheel nut is an M16 x 1.5 nut. The original nut cannot be used.

ATTENTION: Observe tightening torque: 110Nm

The original cage for the nut must be used! We also recommend some medium-strength Loctite, also on the polygon.

Care must be taken to ensure that the shift pin protrudes a maximum of 1.5mm over the shift cross.
