Xpress XM1 series double joint driveshafts
Xpress have introduced a set of double joint driveshafts for the XM1S M-class 4WD touring car. They are a direct fit with the standard 5x10x4mm steering knuckle bearings and will greatly reduce the vibrations generated during cornering, resulting in improved drivetrain efficiency and better steering response.
