    Who manufactures a 1” level kit?

    So I installed a GM cold air intake about a month ago and had the dealer load the tune. Since the “tune” was loaded the truck’s fuel mileage dropped 2-3 mpg and the check engine light keeps coming on. Each time the light comes on my Onstar states an emission related issue. The first issue was a vacuum leak at the MAF, then the next was an O2 sensor that needed to be replaced and who knows what it is now. Is it possible the dealer did not load the correct tune into the ECM when the CAI was installed? I would be interested to hear everyone’s thoughts on this issue.

    Here is my setup. 7000lbs loaded. Suspension handles it well and the 6.2 tows it with ease.

    I want to replace my factory tires with a more agressive tire. Please show me your pictures of aftermarket tires on factory wheels!

    I have the Pedal Commander on my 19 AT4 6.2. I also had one on my 16 AT 6.2. Definitely worth the money. I bought 420 hp and I want to feel 420 hp, none of this pedal lag crap! Go buy one and put a smile on your face every time you accelerate!

    My guess the tie rod ends have grease zerks.

    Pulled the trigger on a new satin steel AT4 this morning. MSRP was $64,995 price paid $55032 less trade for my 2016 Sierra 4x4 AT $36,712. I walked out paying $18,500. Pics will be coming next week.

    How loud is the performance exhaust in the backseat when you are pulling a trailer and the engine is running between 2600-2800 rpm?

    Can any T1 non NHT owners confirm that the 9.76” rear end is installed on their truck if equipped with the 6.2L? It is stamped on the rear end by the yoke. My dealer has no idea? ? My 2016 AT 6.2L has the 9.76” but before I pull the trigger on a new AT4 I want to confirm the 6.2L still gets the 9.76” rear end. Thanks!

    I have aluminum upper and lower Control arms on my GMC AT.

    My noise is a rattle under the bed when I close the rear door and that is when I hear it. I think it is the skid plate rattling that protects the gas tank. I plan to take it to the dealer to get it fixed.

    Here is my truck with 1.5" level kit with 285/55/20 Terra Grapplers and factory mudflaps.

    I have in my garage right now a silver, black and iridium metallic vehicles. The silver is easy to keep clean looking and the black is almost impossible but the iridium metallic is in between both. Also Iridium hides srcathes better than black. I also have to agree painted bumpers do get scratched/chipped so I suggest investing in the 3M mask that the dealer installs for all those who OCD and do no like chips and scratches.
