X3 Rear Axle - 19"/Pin Holes 1.875" From End (2011 & Later)

X3 Rear Axle - 19"/Pin Holes 1.875" From End (2011 & Later) Upgraded version including collar with set screw and two axle pins. New design strengthens axle by replacing third hole with a notch that requires a collar & set screw for securing to motor. Compatible with all 2011 & Later 3-Series caddies. The distance from end of the axle to the pin hole is critical or the wheel won't lock onto axle.
