4-1/2" HD Rear Super Shackles with Greasable Shackle Bushings

4.5" Heavy Duty Rear Shackles with Greasable bushings

We are working with a second generation Kevlar reinforced polyurethane bushing material that is proving to be another step stronger and more durable.  At this time the new material is only available in the same grey color as our Kevlar tierod end boots.  For more information on bushing color, click here.


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.
