I just lowered my 04 Yukon Denali about 4" using a maxtrac kit. Front spindles and keys and rear springs. Along with the new shocks the truck feels amazing. Very little body roll and not too harsh over bumps. My only issue with the kit is the rear springs didn't get me enough of a drop. I've still got an extra inch or so gap in the rear vs the front. At some point I'd like to bag the truck but wanted to know if it's possible to use bags for the rear now to get me the drop I want even without the adjustment of compressor, valves, etc. New springs are going to be about $200 anyway but if I can jut skip to bags in the first place and save a few $ I'd rather go that route. I'm also hoping that saves me from having to do helper bags for towing my boat too. Too much to ask?
