    2012 Sierra SLT 2500HD 6.0
  1. If the shocks have urethane bushings they will squeak like crazy sometimes, get lube made for urethane to fix it.
  2. From my experience with leveling kit, I'd never do it again. The front rides rough and you loose suspension travel. A 4" lift kit set at the lowest setting with keep your axle/CV joint angles normal and give a much smoother ride.
  3. You need to list your truck year and model, the fenders are different between a Chevrolet and GMC so the decals are in a different location. I never noticed the difference until my truck arrived at the dealer, it was a custom order so I was there when the truck arrived and the dealer installed some of the factory options that were just in the cab of the truck, the decals were one of those items. My truck has the chrome Z-71 decals which are different that the stock Z-71 4X4 decals.
  4. My studs are what hit, just to let you know how tight the fit is. I know every brand of tire varies a little in height and width, but they should just clear.
  5. My winter tires are Goodyear Ultra Grip Ice WRT 275/70R18 with studs. At full lock to the left I have a very slight rub in the inner fenderwell. https://www.goodyear.com/en-US/tires/ultra-grip-ice-wrt-lt/sizes-specs?cta=TireDetailsViewSizesSpecs
  6. Sounds like you need more tongue weight and/or weight distribution hitch with load bars. Did your old Suburban have leaf springs and this one coils?
  7. Sounds like a failing fuel pump. Mine would run and then fall on its face if I tried to accelerate.
  8. Those don't even look like LT rated tires, I tried to zoom in and confirm if they are common 1500 series P rated tires. There is no way I'd put them on a 2500HD.
  9. This is the 2500/3500HD Forum mostly diesel and 6.0 gas folks here. Instead of changing out the radiator, I'd replace the fan with dual electronic fans that you can set the running temps.
  10. The ONLY repair I've had done to my 2012 2500 6.0 is a leaking front axle gasket where two sections of tube are bolted together. Excellent truck so far! Mine is used mostly for hauling a 3,000 lb truck camper and towing ATV's.
  11. It should be the center pin for reverse lights
  12. Yes, I have added resistors in the under-hood fuse block between the relays for the lights so all my lights are on together. Low beams and fog lights are tied together, and when I switch to high beam all lights are on (fog, low, high), it's awesome. The step by step directions are on the Duramax forum, search LML All On Mod. I spent like $1.50 for the two resistors at Radio Shack, soldered them together so they reached between the relays, and then covered with heat shrink for cosmetics. 1 minute install.
  13. That is correct, 3500's do not require the TPMS system. You can install TPMS sensors in your new wheels/tires, relearn the system, and be good to go!
