Why Choose ICS Trailers

Wheel-end seals can share a similar appearance while suiting different bearing and hub arrangements. Matching the 665A cone and 653 cup provides a useful identification check for this version. If the old seal markings are unclear, send through the axle make, bearing numbers and seal measurements before ordering.

• Matching inner bearing components can be checked during the same hub service.
• Cross-reference numbers provide additional identification when the original seal carries a different marking.
