3" or 4" Crabtree shackles?

I've got RE heavy Rudy 4.5" springs on my 84 7 with monster 7" long shackles.

Before I correct the caster, I want to shorten the shackles but I'm not sure how short.

I'm definitely going with Crabtree but am wondering if 3" bolt to bolt will be too short for this springs.

Does anyone have recommendations? Oh yeah, the front hangers were replaced but the back look stock?
Not sure if they can be extended out for shorter shackles.

Thanks

If all of the hangers are in the factory location, then those 4.5" lift springs are designed to be used with the factory length shackles. They will allow the spring to articulate properly as opposed to the sloppiness that the 7" shackles probably had.

The best thing to do is contact Crabtree so you can get an exact measurement.

The bushings go into the springs and shackle hangers which are bolted to the frame, so the shackles themselves don't require a certain "size" bushing.

With CJ springs use CJ spring bushings. With CJ shackle hangers, use CJ shackle hanger bushings.

Ok...so I removed the front shackles to find 1.5" OD bushings in the RE springs, and some sort of 1 piece blue bushing in each of the Rock Equipment mounts.

I believe they are 1 piece because I have yet to figure out how to remove them to measure.

Does this sound right / possible?

Jeeps use 1" bushings and wranglers use 1 1/4" bushings, so if the springs were designed for a Jeep then use the 1" bushings. Blue bushings come from BDS. They may be like OME's with 2 halves and a steel sleeve inside.
Either the 3" or 4" (1/2" lift) will work fine with your springs. Personally I'd go with the 4" for a bit more flex but your 4 1/2" springs alone should give you plenty of clearance.
