Soa Question

[skerriltj]

I'm working on my lift and I'm trying to figure out how to properly position my leaf springs mounts for an SOA conversion. Does anyone of a build thread or what to do? I can't seem to find a real good write up. I will be taking my axle off to get them welded. Thanks!

You can look through my build thread as did this a few times. Really simple once you gget to messing with it. Seems more complicted at first. But just get yourself a welders angle finder magnet one and couple jack stands and one stand to put under your yoke to hold in place once find good pinion angle. Then set perches on axle tube and set them level and to the proper width. Look up t&t ube install in writeups as well..

Thanks MiNi Beast!

And the required pinion angle depends on the type of rear driveshaft. With a double cardan joint up on top by the trasfer case (commonly done with a slip yoke eliminator) like the front driveshaft, the pinion should be straight in line with the driveshaft (actually, about 2 degrees lower, so it will be in line under power when driving down the road). If you run a stock style driveshaft, the pinion angle should theoretically be parallel to the transfer case output shaft, or again 2 degrees below that in the real world.

 

The two degrees is for leaf spring applications where axle wrap is possible. With ladder bars, a bam bar, or multilink suspension, the 2 degrees below is not neccesary and would actually be a bad thing.
