an 00 2500ld is a new body style right? eight lugs?

if so then the bds kit is going to be a spindle lift just like fabtech. same exact thing.

of the spindle kits i think RCD is the best. cuz of the bilstein shocks

the spindle lift replaces your steering knuckle with a taller one, leaves your upper control arm in the stock location, drops the lower control arm 6 inches, and drops the diff about 4.5 this results in 6 inches of lift, with CV angles increased over stock. but the torsion bars are kept at stock settings.

advantages- easy to install and pretty damn strong.
disadvantages- the cv angles can be pretty bad if you crank at all

traditional lifts drop everything 6 inches.
