The vibration is present in my truck but not near bad enough to wright a essay on this forum

Here are some pics of mine.

I would wait 5,000 miles before I mentioned anything about the transmission. I'm sure it's just learning. Drive it like you normally drive during this period or it will have to relearn again.

My spacer is steel also.

I think if I was a salesmen I would research the products I would be selling. I wouldn't like it if a customer came in knowing more than me.

No. It only resonates in 4 cylinder mode. I plan on getting the range to get range to get rid of afm soon.

I ran mine over the axle then dumped them by the spare tire. I would recommend doing that the same. My buddy dumps his right after the muffler and its pretty loud.

I had a 2" put on mine. The shop I got the wheels and tires from installed it for 150. I can't remember the brand but it was the metal spacers.

If you leave the three catalytic converters it will not void your warranty.

That is a good looking truck! Congratulations!!!

I like the carpet in the wheel wells. The new truck is super quiet. It honestly feels like you are driving a luxury car. I'm glad GM didn't go super flashy. They put a new interior in the truck which in my opinion was greatly needed. They also made the front grill look more aggressive which was also needed. They already had a great truck before why make a huge change?
