Shackle lift necessary?

Hello, my jeep has a 4" lift with discos and is going to roll 33"s, should that setup get enough flex or is it best to get a little more clearance between the tires and fenders? How many inches, boomrang or not?


Thanks!

Longer shackles, Do allow more lift, Also they allow more wheel travel. Boomerang shackles keep the shackles from inverting and bending springs. They also clear the rear crossmember An Ideal shackle would be a 5/8" Boomerang shackle

Flex will also depend on your springs. I had a 3 inch spring lift where the springs were so tightly clamped together that I never saw good flex, I now have the RE 4.5 lift and have great flex. Other things to look at are your brake lines, did you relocate them or get longer lines? Finally, yes I'd go greasable boomerang.

I agree about going to 5/8lift shackles.

I had to make a new brake line to replace one that broke when I was installing the suspension so i made it longer than stock. The others were fine, but the previous owner had an.. unorthodox way of changing brake lines, so there was plenty of line to relocate them confortably and with a lot of free room.

Greasable 5/8 boomerang, that's noted. Thanks!
