Yes - I have done a search. :flipoff2:

My question is:

Given a SR with SOA with relatively flat front springs, how much change in pinion angle am I likely to see? Will it increase (good) or decrease (bad) my effective caster?

I would consider the waggie/rancho springs, but don't want or need any more height.

I know I will have to do the driveshaft (length and likely increase the slip joint (probably will make modified shaft using ag pto components).

I also will likely have to make new shock mounts - no problem since I am currently making tube'd front fenders.

Anything else I am missing?

TIA

Caster change would depend on what type of SR you do... I am sure would be close with one of those rock finder bolt on styles, but with the tucked closer to the frame styles I think you would need to recess the shackle hanger into the frame to get the best caster without shims. you might want to consider getting the housing cut and turned to get everything dialed in for your cruiser and not cut corners.

There are too many variables to tell you exactly what to do. Best bet is to flip the springs and mount the spring pads where they need to be. Then cut and rotate the knuckles. It really is not all that hard at all...

All you need is a cutter or a big ol' pipe cutter...

It would add to caster IMNSHO. Why? Because you are effectively moving the axle forward around the arc of the spring (assuming there is any arc left in the spring!). If you have absolutely flat springs it makes no difference.

Complaine is right. Doesnt matter what kit you use, if you put the spring perches parallel to the original's flipping the springs will add to caster ( point the pinion down ). Do the s.r. and flip the springs then set the perches on top of the axle and jack it up under the cruiser with full weight. Set the pinion angle to were youre happy and weld.

Understand - I did the SOA/SR 7 years ago, and I don't want to redo the perches. I might consider doing a cut & turn, but not right now. If I could simply get away with driveline & perhaps a shim, I might do it. otherwise I will wait. My rig has been down since a roll in Spetember, so I want to spend my time wheelin, not fabbin (well I have to finish my tube fenders, grill guard etc (pics when I am done)

I was hoping I could get some idea of what kind of change I would see. MY SR is using the original fixed mount, tight to the frame I have NEVER hit it (it's done like the way Warden's used to do them but w/o extending the frame) and my shackle tube is cut into the frame rail.

Thanks,

FYI, I set my pinion at 1 degree down which gave me 2 degrees caster. My thinking was that since stock caster is 1 degree I could double it and gain 100% more caster for better steering and not much effect on u-joint angle. Had to grind the hell out of the flanges to keep the u-joint from binding but it worked and the steering is decent.

I would say you could get away with it but if it doesnt work for you then forget what I said. :D
