Rear Hangers & Shackles
Important — Read Before Installing
Hardware Parts List
- 2 Spring Eye Hangers
- 2 Shackles w/ Bushings (SH1012-2)
- 8 7/16" x 14 Nylock Nuts
- 8 7/16" x 14 x 1-1/4" Bolts
- 16 7/16" Flat Washers
Installation Procedure
Working one side at a time, remove the u-bolts holding the springs to the axle. To keep the spring pack together while removing the overload, use two large C-clamps placed close to the center bolt on the leaf spring and tighten. Remove the center bolt nut. Slowly loosen the C-clamps and remove the upper overload spring. Clamp springs back together, reinstall the center bolt and tighten. Remove C-clamps.
The spring center bolt must be seated in the hole on top of the axle — verify this before tightening u-bolts. When the center bolt is in place, install the u-bolts, bottom plate, and nuts. Tighten u-bolts.
Remove the two striker pad brackets attached to the frame.
Loosen and remove the two shackle bolts and remove the stock shackle. Test fit the new shackle and check for interference on the bottom of the bed. On some trucks a square bed brace will be in the way of the shackle — cut a notch in the brace wide enough for the bolts.
Remove the bolt holding the front of the leaf spring to the front spring hanger. Remove the rivets holding the spring hanger to the frame using an air chisel or by drilling out the rivets.
Mount the new DJM spring hanger in the original holes on the frame using the hardware provided. The gas tank may need to be moved to gain access to bolts on the driver side. Raise the axle so the front of the springs can be located in the new hanger. With factory bolts, attach the spring to the hanger and install nuts — do not tighten yet. (Some may find it easier to attach the spring to the hanger before bolting the hanger to the frame.) See Fig. #1 for typical hanger installation.
Apply grease to the bushings and inside sleeves. Attach the new shackle on the frame mount and bolt in place with factory bolts (Fig. #2). Shackle installs with bushings down and open side forward. The hole farthest from the bushing will lower the truck more than the closer hole. Raise the rear axle high enough to align the spring eye and shackle. Insert the remaining bolt and install nuts.
Install rear wheels and torque lug nuts. Remove the jack stand and floor jack. Check the height of the rear — you can adjust the height by moving the spring to the other hole in the shackle. When satisfied with the height, install new shocks (DJM #1800) and tighten all bolts.
