ORD Rear SuperShackles

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.  We also build them in different lengths for custom suspension applications.  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.  The "long" length is 6" center to center for improved shackle swing.

Looking for a nice flexible rear suspension?  Try our 6" SuperShackles with a '88-'98 GM truck spring and our 2.5" shackle flip kit.  This will net you a 4" lift with great suspension action and control.  This system was the choice of Petersen's 4Wheel and Offroad for the UAK10.

Our greasable bushing setups use a greasable bolt with a zerk and a special bushing with grease cavities in it.  These bolts are higher quality than grade 8 and the hole makes virtually no difference in strength.  A greasable bolt and bushing setup will flex and ride better and the bushing will last longer!

Notable spring bushing information (these are general guidelines, it's best to measure):

52" rear springs (came in the rear of 1/2 ton GM trucks from '67-87 and some suburbans) generally use 1.5" bushings at each spring eye.  The '88-91 Blazers and Suburbans could have 1.5" or metric spring eyes (the '88-98 spring bushings, ~1.7").

56" rear springs (typically found in '73-87 3/4 and 1 ton GM trucks and some Suburbans) use a 1.75" bushing at one end and a 1.5" bushing at the other.

64" springs from an '88-98 GM use a metric spring bushing, roughly 1.7".

8" Skyjacker and Superlift rear springs use a unique bushing, kits for those are below.

These shackle works on any GM or other vehicle with 2.5" wide springs and spring hangers in either tension or compression shackle applications.

Install these HD rear shackles with the open side to the front to prevent contact with the main leaf of the spring.

With deeper arch springs (6" or more lift) use the longer shackles and a shorter shackle flip.  An example would be a 12" total lift would use the 2.5" shackle flip, a 6" HD rear shackle and the 8" lift spring.  The longer shackle length helps keep the shackle from inverting to the front or back.  There's nothing wrong with the 2.5" flip / 6" HD shackle combo for shorter lifts either but it's essential for taller springs.
