Congrats the 6.2 is a nice motor.

Not true i have a 2018 Sierra All Terrain 6.2 double cab with painted bumpers and vented seats.

I don't get the big touch screen. I t doesn't look good and you KNOW it will have problems down the road and cost a fortune to fix.

That big screen would make me not want it. Wait till those things have problems going to cost big bucks.

If you don't have headers go with the louder muffler. Exhaust manifolds and cats really quiet down. I had a corsa sport exhaust on my 05 gto and it was pretty tame. Then i put headers on it and it sounded like a race car when you got on it. I couldn't believe how much louder the headers made it.

Does the engine have iron heads? If so it most definitely has the long crank.

After my 2 sightings nothing for the past 2 weeks.

The GMC wheel wells are horrible. Why did they do that? It looks like they forgot what they were doing halfway through.

My buddy just bought a 2019 f150 4x4 5.0 10 speed with 3:73 gears and that thing rips. The 10 speed works great with the 3:73 gears even so many on here say they don't need those gears with a 10 speed. If 4:10's were a choice he would have went that route. So far he is averaging 19 mpg.

Was the lifter that rotated an AFM lifter?

I worded it wrong i meant AFM cause the shudder. My 8 speed shifts perfect all the time with the range connected. With the range disconnected i get some shudder sometimes and i have only driven 25 miles with AFM active.

My buddy just bought a f150 reg cab 10 speed 4x4 with 3:73 gears and that thing rips. He took me for a ride when it shifted to second it got sideways and when it shifted to third it chirped nicely. He loves it. Still new with less than 2000 miles but he traded in his 2016 DC 5.3 4x4 3:42 gears and he said there is no comparison in power. He said the ford blows the chevy away. We will see how it holds up since he puts close to 25000 miles on a year.

I think the shudder problem is caused by the AFM.
