Truck front springs on a Wagoneer?

[72jeeperjoe]

I swear I read a thread at one point that someone mentioned putting Jeep truck springs on a Wagoneer. I measured the pair of springs I have from a J3000 and eye to eye they are about three inches longer, however the Wagoneer springs are very saggy. I am looking for anyone who has done this. Thanks!

On the '76 and later FSJ's you can swap springs around between the trucks and wagons/Cherokees. A member here even swapped J-20 springs under his Grand Wag for towing. Not too sure on the later models, though.

Front springs are interchangeable between all 74+ FSJ's, and rear springs on all 76+ FSJ's.

On 73 and older Wagoneers and trucks the front springs are not interchangeable. The rear springs are between Wagoneers and certain year/GVW trucks.

Things changed in regards to the rear spring bushings sizes in 74/75, I don't think they interchange with any other years. Could be wrong though, I've never had one so I've never looked too hard into it.

Thanks for the info. That's what I thought.

Rear spring post mounts are their own animal on 1974-1975 J-Truck models. No others match them two years.
