    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I plan on doing 3:73 or 4:10 diff ratios, I dont feel like dealing with any downtime. Do the Yukon and Tahoe's that are 4wd have the same front diff as the AWD Deanali's fron 2007 to 2014? I dont care about the guts as I also want to do the Yukon Lockers and gear sets.

    Pacesetter Headers

    Speed engineering is where it's at , I tow and spend a lot of time in the 3200 to 4000 rpm range for hundred of miles and no issues with mine at all and fitment was spot on . Make sure you get some ceramic plug coils though the stocks will rub and burn.

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Built and painted shelves in the race trailer then towed it to WV only to have the power steering line fail and leak all of the fluid out down at the track. Drove it back home and the pump was not happy at all. I really need to get 4:10 gears and a mitso radiator installed to keep the coolant...

    Front Sway Bar Bushings : 10mm

    Dont guess at drilling it straight get an auto center punch and do that a few times dead center and when you step drill it you will be able to pick the treads out.

    MPG towing and not towing (if not in right section please move )

    Interesting about e85, I thought about it before last weekend but the area of NY I was going to is remote and it was even hard to find 93oct up there. I used manual mode last time instead of tow haul due to it up and down shifting more often than I liked.

    Super steed grades put a really big load on the engine towing in 4th, towed just fine at 4k the entire trip . No issues at all and trans temp never went above 175 in 95 degree temps.
