Question about shackle bushings

Tried searching but got more confused than ever, I put boomerang shackles on my YJ but the front bushings are worn out and need replaced. I ordered 2 leaf spring shackle bushing kits (consist of 4 bushinga and 2 sleeves).
Are the frame to shackle bushings and spring to shackle bushings the same size?

Basically, Are these the same size bushings?

No, the frame bushings are different than the spring bushings.

The bushing on either end of the shackle are the same size. The bushing on the other end of the spring is different in most cases. The shackle end has 1/2 bolts and the stationary end has 9/16 bolts.


Having the proper bushings matched with the proper length inner sleeve is the most important part of this whole project. There are all sorts of thread about leaving the shackle bolts loose so it will flex but all that is because of the wrong inner tube length.

So if I order 2 of these...http://www.oreillyauto.com/site/c/de...3964&ppt=C0361
It will replace the 4 bushings and 2 sleeves in the front of springs and the 4 bushings and 2 sleeves in the frame mount where the shackle bolt up right?

Do yourself a favor and get a complete kit with greaseable bolts from MORE. I went the same route with shackles from here and bushings from there and bolts from another place and no matter what it just never worked right. After replacing everything the amount of flex improved instantly and the ride got a little smoother and more quiet.

Check for sales, discounts and coupons.

I agree, Go with m.o.r.e. Just call them up and tell the the brand of springs you are running. No second guessing or trying to find the right bolts. It is spendy but you will be rewarded with a bolt on deal.

OK for future refrence, YES, the frame to shackle mount bushings are the same as the front leaf spring to shackle bushing. Just installed my energy suspension poly leaf spring shackle bushings autozone part #2.212OC $30 for 2 sets compared to $54+ from my local auto parts.

Good question and the answer is that it depends on what brand springs that you have.

On my Yj the main and the shackle bushings are the same size.
