Why Choose ICS Trailers

The main ordering risk is choosing a washer with the wrong bore or outer tab profile. Compare the removed washer against the 89mm ID, 126/108mm profile and 1.5mm thickness before ordering. ICS Trailers can also help with the matching Propar axle nut and surrounding wheel-end parts when the hub is already apart for service repairs.
