'73-91 GM Front Upper Shackle Hanger Kit

The stock upper shackle hanger takes a 1-1/8" bushing which just isn't up to heavy offroad use. Our fix is simple, we build a new bracket to take a bigger bushing. This replacement hanger bolts into the factory bolt holes and uses a 1-1/2" bushing with a 1/2" shoulder along with a heavy wall inner sleeve and a 9/16" bolt. This should be the end of upper shackle bushing durability problems.

This is the answer to big trucks with leaf springs and hard offroad use. The bushing size difference is pretty obvious and so is the durability difference. Our FUSH is also popular for guys converting to longer springs and especially when using longer shackles with increased leverage over the bushings.

The FUSH kit comes with premium Grade 8 bolts with hard washers and locking nuts. Installation requires removing the factory rivets, drilling the holes to a slightly larger size (7/16" drill required) and enlarging the central hole in the frame slightly.
