Thanks man! I got my gears done at Tarheel 4 wheel drive in Charlotte, NC. They are Yukon 4.56's. If I had to do it again, I would go with a TrueTrac in the rear.
Thank you! Unfortunately, I do not know the answer to that question because I have never had it on a dyno (pre or post mods). Plus, with changing the tire size and not the gears (yet) it makes it even tougher to tell, as it is not as "chipper" as it used to be when I was running 285s. I am planning on putting in 4:56s soon, and the truck will be back having more get up and go.
