Another BB question... shackle vs bastard pack

[ChiliRed98]

Hey all quick question.

I just picked up a set of TJ canyons with 30x9.5x15 Dayton Timberline AT on them and all is well so far....no rub or anything. I want to give the jeep a bit more lift now that I have them on.
I currently have a set Quadratec/Crowne HD spring in the rear and stock up front. I Measure 17 3/4" up front and 18" in the rear. The guy I got my wheels has a TJ and has 1 7/8" coil spacers which I'll be picking up for $20. (Am I correct in assuming the fronts will fit the front?)

My whole question is about the back...I have my old set of warn out leafs laying around...should I bastard pack them into the HD pack for 2" ....is it worth it and which to add for only 2" ...I read a majority of people get 3"-4" out of them. .
OR
Should I just pick up a set of rear 1.5" - 2" shackles and call it a day since I have newer "stronger" HD springs which may make them less prone to sagging?


Spark notes: Bastard pack HD spring for 2in or just buy 2in shackles.

Thanks in advance! :wave1:

I would get the longer shackles for the sake of a better ride, but it will change your pinion angle. You might have to use shims to get the pinion back to stock.

add a short leaf and do 'manche shackles

Ya, I considered that especially since I have a 97+....when I bought the set of HD springs off another Jeeper they came with shims...how do i measure what degree they are?
