4-1/2" HD Rear Super Shackles with Greasable Shackle Bushings
4.5" Heavy Duty Rear Shackles with Greasable bushings
4-1/2" HD rear super shackles, pair, with greasable bushings/sleeves/bolts for the shackles. Bare steel.
After seeing some thrashed rear shackles, we decided a beefier system was in order. These are folded and fully welded 1/4" steel with a .250 wall tube. The back gusset is extended down the spring mounting "ears" to keep them from bending.
The "short" length is 4.5" center to center which is the same as a '88-'98 GM and 1/2" longer than a '67-'87 GM trucks.
Does not fit '69-72 K5 unless shackle flip is installed due to body mount interference.
