Why Choose ICS Trailers

The key ordering risk is mixing this 120mm M52x2 nut with the smaller 110mm M42x2 ECO version. Compare the removed nut, thread and hub family before ordering. If markings are unreadable, send photos and wheel-end details so ICS Trailers can help identify the correct version.

• Match the washer, locking pin and locking ring during the repair.
• Check the 80mm A/F and 120mm body before installation.
