Shackle angle after shackle reversal (1 Viewer)

[Mopdog]

I set the distance between the front hanger and the rear shackle as they were before the reversal and as recommended in a couple threads on here. That said the spring is barely separated from the frame at all at rest. Should I extend the shackle, move the from hanger slightly forward, or both?

extended shackle, you want the angle of the shackle similar to what you have currently, moving the front forward would make the shackle more vertical which would be a harsher ride.

That’s what I was thinking but I am at a good spot to move the front mount if necessary. I have the whole front clip off.

Yeah, you need more shackle. FWIW, I stopped going through the frame long ago, for the reason shown. Ruff Stuff shackle hanger works fine.

The urge to stay low may have gotten the better of me. I used their front hangers and probably should have kept up the theme.

Based on the pic you posted, I would guess you could get away with 1/2" to an inch longer shackle and clear the spring end with the spring compressed flat.

It doesn’t look like it will take much. I’ll probably make a couple lengths so that when I test them I can just weld some bolts through the flat pieces at the length that looks right.

If you like where your axle and tires center in the wheel wells, then get longer shackles. If you like where the wheels center and WANT to pull the hangers forward, you could drill new centering holes in the perches, to bring the axle back, or have new springs built to compensate.

And when you get ready to get much better alignment on your slave cylinder mounting arrangement contact me.

Longer shackles will get her done. I like to put mine through the frame also.

I don’t think I have ever seen anybody try to reuse the OEM shackle when doing the SOA. Cool. But longer will solve your issue.

I also usually flip that leaf with the military wrap to the front also. Flip it and redrill new hole , or like some they extend wheel base and flip the whole spring.

I’ve seen it work when they’re hung from a normal hanger set up as a shackle reversal as opposed to going through the frame. Ideally, you wouldn’t need longer shackles when retaining stock length/height springs.

I cut the perches off the frame and welded the front perch here behind the axle and the rear to the front with 2" square tubing in the front and it worked very well with a great improvement in the ride. It also provided a place to use the Hi Lift jack to raise the front end that was more secure than just the bottom of the bumper. I don't have a clear photo of the front end of the spring.

Before I started cutting I took a square and laid out the frame with a square and soap stone and drew a line through the pins and then once the perches were ready to weld on transferred that line through the center of the hole and welded them back on. This was done during my first semester of welding in college. I didn't need extended shackles on the front just the rear axle.
