12" shackles!?......... a DUMB way to get a 6" lift, hell that would probably even shorten the wheel base some!
Lift shackles SUCK! ive got em 1 1/2" lift and in the front they change the caster too much ( need to compensate with shims or upper ball joint eccentric) the friggin thing bounces between the curb and the yellow line going down the road. they flex alot when you turn the wheel side to side. in the rear they seem to be ok and actually help point the rear drive shaft at the t-case which is good if youre running a big lift and a cv drive shaft, not good if its a non cv driveshaft.
