I am thinking about lifting my 03 GMC Crewcab 2500HD Duramax and was wondering what is the best 6" Suspension lift kit for this truck to keep the best ride and steering angles? Also what is the best Tire Rim combo for this truck where it will not kill the fuel milage and rob any pulling power?

well i just lifted my truck with a rcd lift and it really rides like stock, the steering angles are like stock because of the taller cast iron knuckles that come with the kit keep the steering parts in the factory location. about rims and tires- the skys the limit. make sure whatever lift you get; the wheels have the proper backspacing so they dont rub on the new steering knuckles

hey hdroadking, i was wondering what width rim did you use? i have 16x10 and 305/70/r16 rims/tires on my truck now and im thinking about putting 315/75/16 toyo open country m/t on the current rims, but im wondering if they will rub on the front bumper? how much are the torsion bars cranked up on your truck? thanks in advance

well i have a fab tech 6 in lift and i like it the truck rides great. about the wheels as said above make sure you get proper back spacing i have 325x60x20 toyo open countrys on my truck ,and the back space is off just a little bit and on sharp left turns the right front tire rubs the sway bar.my pics are in the photo gallery red gmc.

cut the bumper with a plasma cutter, take a sawsall to the fenders and buy flares then go to a good tire wheel guy. i can fit 35's w/ no lift.

H2 tires/wheels will fit by cranking the torsions up and trimming the wheel wells, so it is possible. Wheel size and offset makes a huge difference, too.
