I've got a 06 DC TRD O/R with Donahoe Racing 2.5" coilovers up front. I just bought the truck and haven't had a chance to off road yet, but I like the feel from the upgraded suspension. The 2.5" coilovers provide about 1.25" more lift up front than my 3" rev tek lift on my 05 TRD Sport.
I'd like to upgrade the suspension in the rear but I'm on a tight budget and not sure what route to take. The truck has 57K miles and i'm not the original owner. Would I qualify for a TSB? Am I better off spending less than $250 for a leaf pack, aal, or rear bilsteins? My goal is to lift the rear 1-2" and provide a smoother ride that can also handle my quad in the back when necessary.
