Thanks, guys, for all the comments and feedback. One thing I'm gathering from most of the comments is switching to 4:10 gearing. My new air ride system and brakes arrived yesterday, and will be getting installed over the weekend. I'm now looking into getting the gearing and a new trans. My mechanic recommended the parts he currently runs in his own Denali ( see photos ). Have you guys ever heard of or used these, and are there any others that you might recommend? As always, all comments are greatly appreciated, and thank you in advance.
PS I changed my own seprintine belt yesterday.
