94-02 Dodge HD 4 inch shackle reversal

Currently the rear of your truck has a tension style shackle hanger (shackle points towards sky). Our shackle reversal replaces that stock bracket with a much stronger bracket that points the shackle towards the ground creating lift. Everything else about how your truck rides is kept the same!

Typically, a truck is lifted with either a lifted spring or a lift block. A lift spring uses a higher spring rate resulting in a stiff lumber wagon ride. A lift block add more leverage causing axle wrap/hop under acceleration. Lift blocks are also notorious for falling out and causing terrible accidents.

A shackle reversal allows you to keep your stock spring rate and does not have the hazards of using a block. Some auto manufactures came stock with blocks in the back. The shackle reversal can replace those blocks allowing more traction for towing, off-road, or fun burn outs!

NOTE: With our shackle reversal you can re use your stock shackles!

Nope! It will drive just like it does now, in fact many newer heavy-duty trucks are running compression style hangers like the shackle reversal for your truck. Also if you are replacing your current blocks with a shackle reversal expect it to handle way better! No more extra leverage on those leaf springs causing axle wrap. 

Very easy!

1. Safely lift/jack truck up and put on jack stands. Make sure to use proper safety gear and equipment
2. Locate rear shackle hanger and remove shackle/leaf spring from it
3. Remove rivets holding shackle hanger on frame. This can be done super fast with an air chisel. Another method is using a cutoff wheel to cut an X in the rivet. Then take a hand chisel to the heads to remove them.
4. Bolt in shackle reversal and torque bolts to 38 FT/LBS. NOTE: SHACKLE REVERSAL OFFSET GOES TOWARDS FRONT OF TRUCK!
5. Bolt in leaf and shackle into the reversal. The rest is reverse of removal.
6. After driving 100 miles make sure to re-torque bolts

Note: Adding a shackle reversal may change pinion angle in some cases, If you do need to correct your pinion angle a shim is usually all it takes to correct. Shims can be purchased at most drive shaft shops.

Note: The bracket lift height is based off of what you are at now. So for example if your truck came with a 2" block and you use a 4" reversal bracket it would be 4" lift keeping the block. If you remove the 2" block you will end up with 2" of lift above stock (4" reversal - 2" block = 2" lift).

Note: We have found a couple variations in the top mounting holes on these trucks, majority are spot on but the lucky few seem to be half a bolt hole off. This little variation can easily be fixed by opening up the bolt hole some. The bottom holes line up so no issues there. 

 HOG TIP: Shackle reversal will typically move the axle forward some, so use one of these axle relocation plates to get it where you want click HERE

HOG TIP: Looking to gain more lift in the rear? Use a set of our 2" lift main eye brackets! Used in conjunction with our shackle reversal you can gain 6" of lift! Check them out HERE
