as written in the description are the happy owner of a 2002 silverado 2500HD LB7 diesel engine, 4x4.
I would like to install a lift kit for 6 "and I want to understand what the best kits on the market. are still undecided whether to mount a full drop or a kit with bobbins, also because I have not yet understood well the merits of one and the other system.
can you give me some advice?

currently I mount the 285/75 r16 on original rims.
you would put something like wheels and tires after the rise, as most kits do not fit the original rims? I was thinking of putting wheels Hummer H2 with 315/70 r17. What do you think?
