My truck was 6300 lbs with all its junk in it from stereo equiptment, toolbox and cab compartments full of junk mud caked undercarriage and so on 02 ext cab 1500 z71 6'' lift 35 toyos 16 mickey ts. It has 4.88 gears, hypertech, Cai plastic, granetelli maf, msd 8.5 wires, and ran a 16.3 1/4 mile. After taking as much away from the truck as relatively possible while remaining free and decent I've gotten it down to 5000lbs with me in it and I'm 150. The truck is at a 14.9 and only change HP wise is went from hypertech to nelson tune. Truck is so much more fun to drive and still got a couple hundred lbs to lose but its gonna start costing me. The bulk of the items in weight loss is front diff driveshaft and bracket, swaybar, toolbox traded for tonneau, rear seat, a/c, radio, cutting down and removing misc underhood brackets, spare tire, Reese hitch, tow hooks, fog lights, some in dash and center console metal brackets cut down and some other stuff I'm forgetting but nothing too permanent to go back. The truck slowly "lifted itself" 2.5 inches more than I wanted so I cut my 5.5 inch rear blocks in half and the truck sits almost where it used to with the 5.5. And dropped the front accordingly. Free lift kit,, if nothing else lol. But no one iv seen has done a before and aft weight red gain thread so I figured I'd post my experience enjoy and lose weight or gain power , preferably both

 

Next is rollpan 160 tstat longtubes and single out exhaust forgot to add before I have flow 40 1in2 out before and aft weight loss

 

160 stat isn't necessary. The LSx prefers to run warmer.

 

I need to put mine on a diet

 

my 2500hd weighs 6600lbs it needs a diet lol

 

I can't believe all the items you removed added up to 1300 lbs

 

yeah thats wild.
