Few questions with my drop. RCSB 4x4 (measurements and chevy lean)

yeah, contact them and see what they say, I am clueless to the suspension on the SUV's, most of the time you do any changes to suspension you will need an alignment, is it always critical, no, some may only be a tad bit off, but still withing the allotted spec safe range. I'm anal, and get it done every time. DNW to buy new tires from shitty alignment, but I have a lifetime on my alignment.

Didn't know all that was involved with your suspension. Just good info to have at a later date.

This is on my reg cab, not the tahoe.

Are you running 4" djm lowers?

I think they are 3" Djm lowers, but im not sure..whatever NorcalSS sells for a 4" drop. I have the same ones on my tahoe and i think that is around a 3" drop with stock keys..I have drop keys on this one with the arms.
