they are cooper discoverer stt's, i cant decide whether to go with the 35s or 37s

country_09

Either or, they're great tires, but do you daily drive it? I'd go 35s just to save your truck a little stress from the heavy tires

Chevy-guy3

Yes I will most likely drive it daily to school. If not daily then very often

country_09

37s are very heavy, 35s aren't light either though. 35s if I were you just to help your truck out

Awesome! Thanks! If i went ahead and did the full total of 6 in lift, would it look bad with a huge gap? should I just do a suspension lift instead of both?

I had an 05 2500HD that I put 2.5" front Readylift leveling keys on Search results for: '66-3050'. In my opinion It was a great kit. I got the stance and height I was looking for. At first I had issues with the ride quality but after speaking to one of the guys at Readylift I realized I had messed up and had the keys torqued up too high.
