  1. Just say Hey Siri. Call “tp for my bunghole mobile”. And done. Never have to take your eyes off the road or try and hit buttons on the steering wheel. Plus I have 4000 contacts on my phone that I don’t want On Star to have. Sent from my iPhone using Tapatalk
  2. 2in I think. Dealer did it. No trimming. They rub at full turn. Had the same one on our 2015 Yukon xl. Actually just kept the tires from it. They only had 20k on them. They actually stick out past the wheel wells a little on these 22s. Gives it a good looking stance. Drove 80 miles today on highway and still got 20mpg on the computer. No speedo Calibration done either. This thing cuts thru the air better than the Yukon or could be the 10speed trans. Sent from my iPhone using Tapatalk
  3. Not a truck but it’s a 19 next to my 19 truck. New kid hauler. Leveled with 285 50R22 Nitto Terras. 6.2L 10speed in both. Sent from my iPhone using Tapatalk
  4. Still no issues. Its worth a try. Tapered end towards the front.
  5. What is that on the hood? I want one. Do they make it for GMC? Is the bumper molding different also?
  6. Yes. Technically it raised the axle connection to driveshaft probably over an inch or 5 degrees. Removed .25in from front and added to the .25 to rear of the block raising the axle connection point a considerable amount. Essentially by turning the shim around it made the u joint angle almost zero. On really hard stops I can feel it slightly but I think that’s the axle nozzle rotating downward putting extreme pressure on the U joint and drive shaft transmission not wanting to downshift smoothly that causes the vibration at shift points. This all bs that makes sense in my head but I’m not a mechanic and have never replaced a u joint or drive shaft. Just happy the truck stops smooth again and I can think about other mods like rock lights and mufflers. Already got the rock lights. Lol Sent from my iPhone using Tapatalk
  7. DONE fixed it!!! The blocks and shims were installed according to BDS instructions. The rear 5in lift block itself is flat but BDS directions say to use the factory shim the same direction as it came on the truck. tapered end facing rear. Had my lift installer flip the shims this morning so the tapered end faces the front. I can't even believe what a difference it made. SMOOTH STOPS ARE BACK AGAIN. It also cured my roar at 75+. Smooth stops and no more roar. I couldn't be happier. A little ticked at BDS but letting my installer deal with them. Even the acceleration is smoother. I am curious to see if my mpg gets better because of it as well. If you guys will tell me how to measure the driveshaft angle to axle I will get you that info. I have to go back to driving the truck around now. LOL
  8. That’s how the blocks are installed now. .25in higher towards front. So you are saying that’s correct. Well still excited to try it. But I do think the problem is with the torque converter or trans. Could be the programming of these. Have any of you put a speed calibration accessory. Maybe that would fix it. Or at least help a little. Sent from my iPhone using Tapatalk
