Spindles are good quality, instructions suck. Had to cut/mod my lower control arms to make them work..heres what I did
At full suspension droop, the lower control arm (LCA) would hit the spindle and bind up the steering. So I cut off part of the LCA's "skirt" at the bottom to make room for it to cycle up and down w/o binding.
Since the spindle moves everything down, the calipers now hit the steering stop where there original spindle would hit. So I ground down that lil button to make room for the caliper but also leave some there in case I ever went back to stock
The ABS sensor hold down bolt would hit the LCA skirt as well, so I cut a lil section of the skirt off to make room for it.
Without these mods, turning radius sucked and it was going to break the bolt head. Again, none of this is covered in the general instructions they send you. My truck had never been aligned so I needed a camber kit as well. Hope this helps and thanks for the compliments
