Replacing leafsprings

I am looking to replace the leafsprings on my old cj, they are stock and sagging a little on the right side. I was wondering if there was another car that had the same pattern as a 79 cj5 in the leafsprings mounting area, something like an old jimmy that would be a little newer but salvageable out of a junkyard. I'm in high school so I'm on a budget and not looking to spend hundreds and hundreds of dollars for the price I'm finding for new ones you could easily buy a lift. I searched around and didn't find another thread like this one. Any input is helpfully. Thanks

Nearly all the other vehicles used wider or longer springs. Many of the others only used leaf springs on the rear and then they were flatter because that were SOA.

You can look here ... http://www.generalspringkc.com/index.php?p=catalog&parent=145&pg=1


but after a quick review I didn't find anything I thought would be worth it due the the conversion required.

You'd be better off finding someone that's wanting to sell stock springs after installing a lift.

Hey green...I am already putting together my parts to do the same thing.Here is some research I've done on this site and others and from puttin the trusty measuring tape on it.Search "yj to cj leaf spring swap".The rears are direct swaps.The front is not.Your cj leafs are 2" wide on the front and 2.5" on the rear.From what I can tell on the front....I have to remove the 2" shackle hangers and replace them w/ 2.5" rear hangers.The cj shackle can be replaced w/ yj or aftermarket shackles.The front spring plates need to come from a yj BUT you must somehow fab the swaybar mounts because they only have shock mounts.I'm still figuring that out.Thats what I have so far...If I am passing on wrong info someone please post up because I also need to try something different.

Thanks both of you I'll probably look for some one selling some cj springs. The swap ur talking about sounds intriguing but in high school I don't have the time or resources to take on that kind of a job but I will definitely crawl your thread.

You could install add-a-leafs to your spring packs. They will stiffen up your ride but if your stock springs are in that bad of shape they would most likely be an improvement for pretty cheap and give you some decent height.

For these prices and free shipping you probably wouldn't even get shipping on a used set.

If my right side is sagging will it even it out or will it just raise it and make it sag a little higher?

It's hard to tell. It could but it depends on why it's lower... spring sag, collapsed body mounts, or both.

To make things clearer, try to use passenger or driver side vs left and right. For instance, is it the right side as viewed from front... or back?

This forum will help you a lot with your project but try to find a Jeep club in your area and look at what they've done and learn from them.

I know most Jeeps in the clubs today don't use leaf springs but there are still a lot of guys that know what to do with them.

The lowest price I've seen on new springs is JC Whitney. The ones they sell for stock replacement used to be pretty decent for low dollars. Whitney offers a lot of discount and free shipping deals, if you watch for them.

'81 Scrambler w/ FI 360 AMC, 33x12.50 BFG M/T's, 5" of lift, ARB'd Dana 44's F & R, Dana 300 clocked & twin sticked w/4:1, Warn XD9000i, etc...
