Howdy, Im new to the truck side of ls1tech. Been a member to the car side for awhile now, but i just recently purchased me a ls-based truck. Its a 06 crew cab z71 fully loaded. I dont plan on doing a whole lot to the truck since its a big 4wd truck. It already has ceramic coated longtube headers, ORY, and a catback, all 3in, underdrive pulley, CAI, and a 87 octane dyno tune. The mods really helped the truck out a lot. I am getting a little over 20mpg on the highway. I mainly just wanna keep it maintenanced and maybe a little bigger tires Any advice someone is willing to give me on this truck I am willing to listen.

 

Welcome. Nice looking truck.

 

Thanks! I would like to put a little better gearing in it, that way I can put a little taller and more aggressive tire on it. The 06s kinda lack in the gears dept. For some reason they stopped with the 3.73s and did 3.42s. Also dont get why they went back to drum brakes on the rear? Kinda odd for a $36k truck brand new
