noob leaf spring question

XJ=Fun · Aug 14, 2009

right now im sunning a 4.5 inch lift spring with a 2 inch lift shackle(both RCX) and was wondering if the shackle angle would be corrected if i were to use a 6.5 rustys leaf pack with stock shackles instead of the rough country 4.5 inch leaf pack + 2 inch shackle. or am i gona need a shackle relocating bracket either way?

4.5" Leaf Packs and 2" Shackles would offer more Flex than 6.5" Leaf Packs and Stock Shackles IMHO. The taller the Leaf Pack and shorter the Shackle... the less Flex available as the Springs would have NO Room to elongate.

Just my .02

ok i see what your saying, but am more focused with on-road manners right now. im wondering if 6.5inch rustys spring packs will have a better shackle angle with stick shackles. right now my shackle angle is horribe with my RCX 4.5 inch pack and 2 inch shackles. it rides like hell

6.5" Rusty's Spring Packs will not. They will have more Arch than anything and may be difficult to Install into the Stock Leaf Spring Mounts and Shackles IMHO.

If you would like more On-Road Manners and better Shackle Angle, I would go with a Longer Main Spring and relocate the Rear Leaf Spring Mount and go with the Shackles you have.

mine is a combination of stock xj's, and two leaves from a 3/4 ton dodge pickup. good for 3.5-4" lift, and rides better than stock.

Order the shackle relocation mod. Then you will achieve more flex AND have a much smoother ride
