Why Choose ICS Trailers

Six-hole hub caps can look alike while differing in diameter, depth and wheel-end application, so compare the 140mm PCD, 116mm ID, 162mm OD and 50mm depth with the removed cap. If the old part is damaged or unmarked, ICS Trailers can help compare photos, measurements and axle details before you order.

• Support matching the cap to the existing axle and wheel-end layout.
• Help identifying the correct gasket arrangement during hub service.
