The XRAY 305370 X4 54mm aluminium drive shaft is engineered to support rear drivetrain duties with durability in mind. Fabricated from Swiss 7075 T6, the shaft combines a lightweight profile with the strength expected for serious performance applications, and the hard coating adds surface protection.
Its hard-coated surface helps resist abrasion from debris and regular running. CNC machining delivers tight tolerances for reliable engagement and reduced play in the drivetrain under load.
Laser-etched markings make it easy to identify the part and verify compatibility. The drive shaft is matched to the X4 2022 model and is often chosen as an upgrade or replacement in rear drivetrain assemblies.
