I just got my new upper and lower control arms from top gun customz today along with a 2 inch leveling kit. Just have a few questions about installing the leveling kit on the truck in my sig. My main concern is am i going to need a spring compressor to do it? I have everything else to do the job besides a spring compressor big enough to for springs this size. The one in our shop is more for light duty car stuff. My second question is does anyone have any tricks/ ideas that may save me some time getting the control arm bolts out of the sleeve in the bushing or should i just cut the nut and bolt head off and not waste my time messing with them. I have all new nuts bolts washers etc. I remember fighting with the bolts on a friends truck and wasting alot of time. Also what is the spec for the pinion angle?
Thanks,
Garrett

 

I dont believe you have to worry with 2inch leveling kit about pinion angle, from what I've read its once you get over 3inches you have to adjust. cut the heads off the bolts IF they wont move when trying to remove them. If you unbolt one end of the track bar, and pass side tie rod & remove the shocks the suspension will drop enough to pull the springs out, some guys use cargo straps to "squish" the coils. I used a small bottle jack on the lower control arm(there is a flat spot there) and a bracket off the frame(almost like they put them there so you could jack from there) and jacked the axel low enough to slip the Carli coils in. the carli's were way longer than the stockers and I had plenty room, you should be OK.
seeing how you are replacing control arms, it might be easier to jack up truck and support axel, remove control arms, lower axel, remove springs, install control arms,

or remove springs first/replace springs/ then do control arms.
either way will be easy I think
