4" lift SUA springs used on a SOA setup

I have a set of front 4" lift springs from a spring under 79 Cherokee chief. How much lift will they provide if I put them SOA on my 73' J2000? It is SOA stock.

Spring over nets you about 5-6 inches add a 4 inch lift you'll be around 8-9 inches but the spring sizes for the 72 are different as they are outboards with different size bushings

0" Lift, they won't bolt up.
'79 is box and hanger mount vs. '73 post mount.
Go compare the two, it will be quite obvious.

'73 was the last year of the 2" wide SOA stock LONG front springs.

Unless you are looking for a crazy amount of lift on your '73 just go SOA. If you want less than an SOA gives you then you will either (A) spend a bundle on custom rear springs to achieve all spring lift or (B) you can get front lift springs and use blocks in the rear. I haven't ever searched for lift springs on a '73 so they might not be available. I honestly don't know. What I do know is that you are gonna get some nasty axle wrap with 4" blocks. I won't touch 'em with a ten foot pole and you holding it.


IF I was in your shoes I'd do one of two things, use the Rancho 44044's (2" lift) with a pair of TT Fabworks spring perches that give some lift and 1" lift shackles or skip all that and just go SOA.

Ignore this post above please.
Your (or any) '73 J200 is already spring over up front.
You are on 2" wide springs mounted on posts off the side of the frame.
44044's will not fit the front of a '73 JTruck, they will not fit the rear either.

If you would like to study up on spring lengths, widths and bushing sizes please refer to this post from Tom at Hellcreek.

HellCreek does make a 4" all spring lift for the '63-'73 JTrucks, BJ's carries the same kit.

Thanks for the correction TAD. Didn't know the earlier style was already SOA. :emb:


It would sure save a bunch of work, etc. IF the newer stuff was this way too.
