Installation Notes

Verify rear axle, shoe size, and drum dimensions before installation. This drum is specified for 5-bolt, 4.5-inch bolt circle applications with a 10-inch nominal drum diameter and 2.85-inch center hole diameter. Confirm the existing drum does not exceed the maximum brake diameter discard specification of 10.06 inches before reuse decisions are made.

For best results, inspect rear shoes, hardware condition, and wheel cylinder operation during brake service. Match the vehicle’s rear brake configuration to the fitment notes, especially on 1984-1989 Jeep Cherokee with Dana 35 axle and 10 x 1 3/4 inch rear shoe, and 1986-1989 Jeep Comanche except heavy duty.
