So I may need new bushings, but aside from that it should be a slam dunk eh?KaiserMan wrote:Here is a cut and paste from a post made by Laher Spring Company on FSJN.
Wagoneers
"1962-73 Wagoneers use 22 x 22 x 2 1/2 inch front springs with 9/16 ID bushings on both ends, and 26 x26 x 2 1/2 inch rear springs with 7/8 ID bushings on the post and 9/16 ID bushings on the shackle.
1974-75 Wagoneers use 22 1/2 x 24 1/2 x 2 1/2 inch front springs with 9/16 ID bushings on both ends (the same as 1976 up), but 26 x 26 x 2 1/2 inch springs on the rear (the same as 1962-73). The kicker on the rear springs is that they have a 1 inch post mount instead of a 7/8 inch like the 62-73's - same spring - different bushing. The shackle bushing is the same 9/16 inch ID.
1976 and up Wagoneers use the 22 1/2 x 24 1/2 x 2 1/2 inch front spring with 9/16 inch bushings on both ends, and a 26 x 31 x 2 1/2 inch rear springs with 9/16 inch ID bushings on both ends. "

1970-73 trucks with a 119" wheel base use the same front spring and the 26 x 26 x 2 1/2 inch spring with a 1 inch post mount and a 9/16 inch shackle bushing.
1970-73 trucks with a 131" wheel base use the same front spring but a 26 x 31 x 2 1/2 inch rear spring with a 1 inch post mount and a 9/16 inch shackle bushing.
1974-75 trucks with a 119" W.B. use a 22 1/2 x 24 1/2 x 2 1/2 inch front spring with 9/16" bushings on both ends, but a 26 x 26 x 2 1/2 inch rear spring with 1 inch post mount and a 9/16 inch shackle bushing.

All of this assums that your truck has rubber factory bushings. If your truck has brass bushings, well, that's another ball game. It seems as though the Jeep engineers set out to drive the aftermarket guys crazy. "
I don't even think you will be able to bolt those springs up without a shackle that is way longer. To use the stock shackle you only need a main leaf that is about 1.5-2" longer.Nikkormat wrote:If im guestamating correctly full droop with the springs 3-4 inches longer on the back end should net 90° at full droop, 60°-70° static, and 40° at full compression. My time lurking in Toyota forums in that past tells me that those numbers should both ride and flex well. Right? Am I crazy or might this work?
