Ideal Shackle Length for 4” Skyjacker Lift? (1 Viewer)

[phishtaco]

Is there an ideal shackle length for the 4” SJ lift? I currently have 5.25” Confer shackles with the crossbar. I would like to use a shorter shackle to reduce height some and possibly remove a leaf. They were originally over tighten by PO. Any recommendations on shackle length? I was thinking 4” center to center, which is about 1.25” over stock.

On the front I have a shorter shackle (I reused an OME shackle) and its fine, rear requires a longer shackle. I'd advise to try the rears with your 5.25" just to see and shorten up if you need to. Here’s a pick of the front.

Mine are 4" c-c.
Shackle angles are pretty good.

x2 on 4" for starters, put em on, add some weight and if shackle angle sucks get shorter ones.

Thanks. Sounds like my thoughts on 4” were right.

with 4" skyjacker springs, I run stock length on front and 2" longer shackles on rear to make up for 4 Plus dual carrier swingout.

Anything shorter than 4" shackles on the rear and there's a good chance the rear spring eye will decide to bottom out on the spring hanger.

Unless you don't leave pavement.

I think originally did 2" over stk and I set up the frt with 4* shims. I found caster was about 0+*, so I shortened them an to 3 3/4" in the frt and rear at 4 3/4" and now have about 1+* caster. It drives fine but will probably go to 6* shims. After 2 yrs of driving and 6000 miles the springs are settling in nicely.
