Hi all. So i have a 2002 Tahoe LT 2wd. Has 215K miles on the suspension but new reflex shocks. I plan on rebuilding the complete front end and plan to install a Ranch Hand front bumper. The bumper is almost 200lbs. I'm going to do the front key's leveling kit. And replace the rear coils with the Z71 coils. I understand i can crank the front up to offset the heavy bumper sag. Is there also a set of front hd coils i could install to help with the added bumper weight?? Maybe front Z71 coils too?? Online searches dont tell me much. Mostly about the rear.
