  1. Well I ended up finishing the first part. It's a 2 inch RC level. The ride is a little rougher. I can feel the road a bit more. There is about a 1 inch rake. I'm good with that.I don't get all the fuss with the kit. I installed both sides in 20 min not including jacking and removing the tires. All I did was jack up the entire front end so both tires were off the ground. Remove top nut on sway bar. Remove both strut bolts. Use a pry bar and push down on the upper arm. Just slid the puck in with some effort and that was it. No removing ball joints ect... I think I'm going with 275/65r18 Falken Wildpeaks.
  2. The 275/70 you have is 33.2" tall. The stock I have is 31.6" 265/65. I like the 285/65, but the more I read I don't think I'm going to do it just because I'm looking more for function than looks. Kinda 60/40... The 275/65 is 32.1" and they don't weigh that much at all. It should still look good with a nice tread like the Wildpeaks and not affect my gas mileage too much. We''ll see. Thanks
  3. That's what I'm looking to do. This Friday I'm doing the 2" RC Level and still debating on the 285 or 275. What PSI did you fill them to? Any Idea in loss of MPG yet?
  4. Stock 15.9 city and 21.5 highway with 5100 miles on it so far. I lost 1/10 a mile taking off the air damn so far. haven't tested on long runs though.
  5. Doesn't the Chevy have a little different profile. I think the GMC looks good without it at all..
  6. Just a couple pictures of my Air Dam removed ( Before and After ). I'll be watching my MPG. Next week I'm doing a 2 inch level. Christmas 275/65R18 Falkin Wildpeaks..Looks much different with it removed though.
  7. I have a 2017 Sierra 1500 and am putting in a 2 inch level lift. The tire Rough country says 285/65 R 18 max size.
  8. I want to get some 285/65r18 tires, but they are all E rated at 80 psi. What do you guys do to stop the sensors from tripping? Do they cause errors? I also really didn't want to ride with 80 psi. Must be like driving without shocks, right?
  9. I just got back from my first oil service at 5000K. I told the dealer about how crappy it downshifts at low speeds. He told me GMC is aware and that is NORMAL...WTF..He told me there was a bulletin on this too. Maybe I'll stop by and get it. I'll post it here. As the other poster noted. I also had a Dodge Ram. It was a 2003 I bought new and shifted perfect from the day I bought it. I sold it with 93K. I plan on keeping this just as long as my ram , but am worried the rear will fall out before then...
  10. I don't have the lift yet, but this shows what a 2" would do. Later today I'll post some pics of a 2.5. You can see the CV isn't too bad, but look at the upper ball joint in both pictures.

  11. Yea I have 18's also. I can see the 265's would be since the factory orders them. I was looking at the 275/65's or even the 285/65's. Those come in E only. Thanks for the info...
  12. Hmm. What size are your's again? I know the the Sierra X Terrain came with them too, but I can only find that they come in E rated 80psi max only
  13. Are those the E rated ones? What PSI are you running?
  14. What PSI are you guys running the E rated tires at?
