2020 GMC 2500 at4, with 6.6 gas and 6, speed trans. The truck is new to me only had 59340km (37000miles) when I got it. I normally do oil changes every 8000km (5000miles). So I'm nearing the first oil change since I've had this truck, it does have very minimal oil consumption. My question is, does anyone use any higher quality oil that dosent have the "dexos" paid approved label. Such as Rotella T6, or amsoil, redline etc. And if so have they had less/or no oil consumption? Thank you

So got the truck back from the dealer they of course cleaned and greased between leafs. And they changed the insulator pads between all the leafs. Driving home there is no clunking so we will see only time will tell. The manager also said if the clunking returns they will change both leaf sets under warranty. Hopefully he keeps his word.

How many times have you had your truck in for this issue for them to agree to replacement? I'm bringing mine in to the dealer for the first time, but I am not going to keep going back either they replace them the first time or I'm going to a spring shop and I'll pay to have have it fixed.

No only when driving over bumps etc. Sent from my ELE-L04 using Tapatalk

I have a 2017 Sierra. There is a clunking in the rear end I've narrowed it down to the band clamps on the driver side leaf spring are loose so the leafs move and clunk when driving. Anyone have the same issue? Should warranty cover this or a TSB? I'm in Canada if that makes a difference. Thanks Sent from my ELE-L04 using Tapatalk

What parts do you have to change in the motor to permanently delete afm? Cam? Also any good brands/part numbers of parts required? Thanks for the help Sent from my SM-G903W using Tapatalk

The rough country 2 in level goes between lower control arm and strut. Is it alright for durability etc? Sent from my SM-G903W using Tapatalk

So i just bought a borla xr1 40943 3 inch inlet/outlet. I obviously didnt do proper research. The stock pipe is 2.75. How do you adapt to get the muffler to fit? Do i need an adapter piece or am i missing something? Thanks for the help. Any pics would help to. Sent from my SM-G903W using Tapatalk

I read driving in manual mode in 5 gear also prevents afm from kicking on. My question is would there be any long term damage caused by driving in 5 gear manual mode all the time except highway? Or is the range afm disabler a safer bet? Sent from my SM-G903W using Tapatalk
