    YJ springs

    Will YJ springs fit in a CJ frame? If not what would you have to change to make it work? Looking for a set of CJ lift springs but not having much luck. Thought maybe YJ springs would be easier to find. Just wondering. Thanks for any info

    Yep. Springs themselves are wider. I believe the length is the same though, so you'd just have to modify the perches and shackles to YJ stock.

    Give that a try. Googled "YJ Springs vs CJ Springs" and go that. There were many more links.

    Front springs on the CJ are skinnier than the back. YJ are the same all the way around. Rear YJ and rear CJ are the same width, that will be a direct bolt in. You will have to use wider hardware for the front. (ie. mount rear CJ hardware on the front of the frame).

    Quoted from Offroad.com;
    The rear springs used in CJs and YJs are the same width, so the rear springs bolt right in. The YJ front springs are a little longer and wider than CJ front springs. The fixed spring hanger for the CJs front spring is the correct width because the CJ front spring uses a wide bushing in the back. It is the shackle side of the CJ that is not compatible with the YJ front springs. Rivet replacement For the shackle end of the front springs, CJ rear spring hangers are the right width and only cost about $14.99ea new. They need to be moved forward so that the rear hole in the spring hanger goes where the old front hole used to be. There is a rivet in the frame at the location where the new front hole needs to be. The rivet holds the cross member in place. I welded the cross member to the frame, ground the heads off the rivets and punched them out. The bolt holes lined up perfectly.
    Thanks to those guys for the writeup.
