Help Lift

[Sierra250004]

I have a 07 vortec max. What kind do I have? Do I have torsion keys or spacer?

[dgreene396]

If you have an 07 Classic, you have torsion keys.

 

If you have an 07 NNBS in a 1500HD, 2500HD or larger, you have torsion keys.

 

If you have an 07 NNBS in a 1500, you have struts and need spacers.

Classic? 4x4?

You have struts and need spacers if you want some lift

there is NO such thing as a NNBS 1500HD. The closest thing you could compare that to would be a Vortec Max.
