Specifications

Your axle must use the 25580 inner bearing (1.750" ID). If your inner bearing is 1.375" (commonly 44649), this kit will not fit. Always confirm your existing bearing numbers or measurements before ordering.

This bolt pattern (6×5.5") matches many GM pickup wheels and standard 6-lug trailer wheels with a minimum 3.50" pilot diameter.
