I am ready to buy a ground force lowering kit, and am wondering if I should buy their kit that comes with shocks?? I have a '99 with 36,000 miles and wasn't sure if my factory shocks could be / should be used.
What alignment specs should I have them use with the new kit? will I even need an alignment after??

Thanks.

 

I'm still using the stock shocks w/ the G-Force setup. They work fine (for what my truck is used for). If you're going to auto-x it, then perhaps a better shock would be best.....but for my occasional weekend drives (I only put about 250 miles per month on it), the stockers work well.

 

I got some Bilsteins to go on when I do my drop. Yes, you will need an alignment done after the drop, but I don't know the specs. It'd be nice to have them, though. Maybe someone can help us out.

DUCK

 

Ford Alignment spec:
L.H. Caster: 6.9, +/- 1.0 Deg.
R.H. Caster: 7.4, +/- 1.0 Deg.
L.H. Camber: -0.5, +/- 0.7 Deg.
R.H. Camber: -0.5, +/- 0.7 Deg.
L.H. Toe: -0.05, +/- 0.15
R.H. Toe: -0.05, +/- 0.15

Base F150: (tolerances same as above)
L.H. Caster: 6.2
R.H. Caster: 6.7
L.H. Camber: -0.3
R.H. Camber: -0.3
L.H. Toe: 0.03
R.H. Toe: 0.03

Lightning Owner preferred:
LH Caster 6.7
RH Caster 7.2
LH Camber -0.5
RH Camber -0.5
LH Toe -0.05 (slight toe in)
RH Toe -0.05 (same)

Lightning Owner autocross preferred specs:
LH Camber -0.7
RH Camber -0.7
LH Toe OUT 0.05
RH Toe OUT 0.05

 

This will sound dumb, but which one of those should I give to the alignment guy after I put the groundforce kit in? It was just aligned about 2000 miles ago, and has been straight and perfect since.

 

If you have 36,000 miles on the original shocks, they probably needed replacing about 25,000 to 28,000 miles ago. With that in mind, any new shock that fits will be an improvement.
