  1. Falken Wildpeak AT3, General Grabber ATX, and Cooper Discoverer AT3 would be my top three choices.
  2. Take it up to highway speeds, and check for the dreaded "chevy shake." If you notice a shake/vibration at higher speeds, then address it with the dealer. Also find out the build date. The late 2015 models were known as 2015i and are more desirable.
  3. As others have stated, it will hold first gear. I've yet to find a reasonable use for it though.
  4. I doubt you'll get much action on this one, because you posted in the HD section. You'll be better off if you post in the 1500 section.
  5. Your best bet for killing drone....go to your local exhaust shop and have them put on a stock 6.0 muffler from their scrap pile.
  6. It would be pointless to get an alignment before leveling, because that's what causes the need for an alignment in the first place, haha. Might as well just wait until the tires are on, and then set the height where you want it. Alignment would be the final step.
  7. Yeah, your shop friend either doesn't know what he's talking about, or he just didn't want to do it. If he has a two post lift, it's seriously a 5 minute job (plus the alignment). If you go with a 295/70/18, you don't need to lift the rear. You might even clear in the front without having to level, but it'll be close. That will probably come down to the exact type/brand of tire you choose. And, regarding that choice, I think there are quite a few better options than Duratracs. For shock extensions, any reputable brand will be fine. Mine are Zone Offroad. For a 2500HD, you'll want load range E.
  8. There are many, many threads about this already, but I'll give you the short version... 275/65/18 are too small for a HD. You can fit a 275/70/18 or 285/65/18 without any changes. With a small level/lift, you can clear 295/70/18 or 285/75/18. These trucks are super simple to level. You can crank the factory torsion bars around 2", get the front end re-aligned, and you're good to go. Adding shock extensions will help.
  9. It'll probably be off a couple mph......unless you get some kind of programmer to correct it. Whatever percentage you increase in overall tire diameter (from stock), is the same percentage that your speedometer will be off. For example, my truck is only slightly off at 50 mph......off 1 mph at 60.....and off 2 mph at 70.
  10. Yep! A good rule of thumb is to check your spare tire. GM most likely uses the smallest rim that'll fit, because it costs less. If your spare is a 17", then that's as small as you can go.
  11. I've had 6 different 1500's over the years, and only one 2500HD. Now that I've experienced how a 2500HD handles "truck stuff," I don't think I'll ever go back to a 1500. Another reason is how I used to set up my 1500's. I always ran a level and larger tires. They didn't ride that great, and the MPG wasn't very good either. I'm only getting about 2-3mpg less than my most recent 1500, and it's a LOT more truck.
