I am interested on putting a 1.25 - 1.5 inch shackle lift on my 94 yj. It is completely stock right now, and i just want to clear 31's. Will a shackle lift by itself cause any different suspension feeling, as in increased body roll? Are there any major downsides to a shackle lift? Thanks for any feedback.
You probably won't be able to tell a difference. I used 2" shackles to clear 31's. My only problem was that my spring were old and sagging. I don't know if that is what caused one to bend or not. Even with wornout springs I still had about a 1" all the way around the rear fender flare.
I bought a '94 w/31's on it and some severely sagging springs. All my fender flares had cool 1/2 moons in them from the rubbing. My 2 cents would be to do a 3 - 4" lift, it looks GREAT w/31's and I'm getting ready to go to 33's. I was on a severe budget so I went with Rough Country's lift. About $400 shipped, and it came with everthying I needed. I didn't have to buy a bolt seperately. I might add a 1 - 2" shackle after I get the new tires and gears, depends on if I need the extra inch or not.
Shackle lifts seem to be pretty popular here, which kind of surprises me. Generally they are not a desireable way to lift a Jeep, but they are cheap.
A buddy of mine had a shackle lift on his Jeep, it served the function of allowing him to clear 31" tires on tired stock springs but that was about it. The front ones hit every rock on the trail, and the rears severely limited his departure angle.
One thing to remember is with a 2" longer shackle you only gain 1" of lift. They can also affect your driveline angles, and possibly cause vibrations, and premature U-joint wear/failure.
I would reccommend saving the money spent on the shackles and get a mild spring lift. Two inch spring lift can be installed without really having to change anything else, except maybe shocks and extending brakelines. Brakelines can also be extended by moving the hard line from the top of the frame to the underside of the frame, and using the rear bolt on the bumpstop as a mounting bolt. Extreme care must be used if you move the hardlines, if you kink the lines you're screwed and have to replace them.
