JKS MFG. JKS OGS651 Rear Shackle Kit for Jeep XJ/MJ

No complaints as they did what I needed: 1” lift and didn’t change my ride quality. The added bonus is that these are greasable and keep stock shackle angle.

as somebody pointed out the 3/16 inch deep cut in the stress bearing surface is a qc problem i just welded over it with a mig welded then repainted it and hopefully they dont kill me. leveled my jeep perfectly now siting at a 2 inch above stock with moog zj coils with 3/4 inch spacer to level one side in the front and monroe sensatrac load leveling shocks and these shackle brackets lifted the back exactly two inches and now its dead level and rides perfect after an alignment.

JKS is all quality and these shackles are examples. It seems the zerk fittings are 1/4 x 28 and do not fit, while the tap is 6mm. I used M6 fittings which fit perfectly.

We just put these on my buddy's XJ because he was having spring slap against the body in the very back over any medium or larger bump. The stock shackles just let the rear of the longer lift leaf springs sit too close to the body (in front of the rear bumper). These shackles faced backwards got us that 45 degree angle we needed and moved the rear eye of the leaf spring bushing back and down a little. This did give us an extra little boost of almost an inch...but it made the XJ ride way better and flat out eliminated that hard slap we were getting. Do both sides at the same time on the install. That will make getting them in a little easier.

Added an inch total over the stock shackles. Heavy duty construction. I agree with other reviewers that switching to a 45 degree angle zerk fitting would be a great mod BEFORE installing. That said, I was able to access the straight grease fittings that came with the kit...but simplify your life by making that 45 degree zerk upgrade at your local hardware store before installing. I did have to spread the ears on the shackles about a 1/8" on both shackles to fit over the leaf spring bushings, but that was easily done and did not impact the fit or installation.

fit well and almost perfect. The powder coating is pretty brittle and chipped off during install. The only other complaint is there is a notch in the shackle were they folded the steel over, not a great design. Would be easy enough to route the laser cutter to make a small circle instead of a notch. Otherwise works great.

Put these on my 01 XJ paired with new Dorman stock height leafs, u bolts, and u bolt plates.They definitely provided the 1in of height and then some. Closer to 1.5in, but over the course of a year it’s settled to around the 1 inch mark, more due to the leafs and not the shackles.The shackles still look brand new and the fact that they have grease fittings is a huge plus.If you love it, keep it lubed.

Overall great product. Only down fall to my order was of the holes for a grease zerks had some powder coating in the threads so i had to rethread that hole but i love the product. I used them on my comanche.
