Guess its cheaper to trade in for a 6.2 and 10speed lol I would of liked to have the 10speed with my 5.3 but for now Iam happy with the 8speed. I know I will loose mpg when I upgrade to 62lb mastercraft 295x70r18 but others are running 70+lb tires; which gives me hope. My buddies at4 5.3 with 33” toyo mt are 74lbs and 12.7 wide is averaging 13.5mpg. I think I can do better lol Sent from my iPhone using Tapatalk

I agree. My 17 silverado with the 5.3 8 speed 3.42 gears had no trouble pushing 60lb 33" mud tires. I would average 15mpg city/highway. My AT4 with the oem 42lb 32" tires 5.3 8 speed 3.23 gears in giving me 15mpg already before even upgrading to bigger heavier tires. I dont know why they didnt stick with the 3.42s at least.

@Lance1980 Most people running a 1.5” level; installed the motofab 1.5 lower strut spacer. Sent from my iPhone using Tapatalk

Same happened to me. I noticed while waiting for them to close the deal. So i told them about as it was listed in the window sticker. They found them in the back and had me scheduled for the weekend to replace them. They did the change in less than 5 minutes. Just pop old ones out with a small flat screwdriver and in go the new ones. Sent from my iPhone using Tapatalk

Here are some pics of my buddies AT4 with no leveling kit just 33x12.5r18 Toyo MT tires (actual factory specs 33”x12.7”). He said there is 1/2” gap between tire and balljoint. That is pretty close but his tires are wide compared to others such as the Mastercraft MXT 295/70r18 which measures 34.25”x12” or the 295/70 Toyo Mt which measures 34.5”x11.8”. He said there was no evidence of any rubbing. Its mainly a city/highway commute truck and occasional beach [emoji907] trips. Sent from my iPhone using Tapatalk

These are my buddies AT4 angles with no leveling kit. Just some 33x12.5r18 toyo mt (actual factory specs 33x12.7) Sent from my iPhone using Tapatalk

These are my angles with the 1.5” leveling kit on mt AT4. Sent from my iPhone using Tapatalk

I have the 1.5” motofab lower strut spacer on my AT4 and the cv angles don’t look bad at all. They were pretty level with the GM factory lift (longer strut) which is probably why the 1.5” space did not change much. The UCA ball joints do not look bad either. I think ReadyLift offers a replacement upper control arm to correct the ball joint angles due to them offering a 2” leveling spacer instead. The CV angles however are not corrected. The 1.5” motofab Is netting essentially a cumulative 3.5” of lift but as opposed to running a 3” spacer on a not AT4/Trailboss the CV angles and balljoints are being stretched after the 2” factory lift while standing level at the factory lifted height. A non GM lifted truck with a 3” spacer is taking the angles stretch from the full 3” height modification. I hope this makes sense. Sent from my iPhone using Tapatalk

I’ve had the mod for several months now and still love it. I continue to be curious about cutting off the flapper and replace with some pipe...to have a fully open system before the exhaust. I believe it should add even more growl since the valve when open is different from the 2014-2018. I can’t find the picture to attach but somewhere on another thread I saw a cut off valve which showed a 1/4 of the pipe still covered when the valve was open. This is do to a perpendicular moon shaped piece welded to the original circular flapper covering 1/4 of the pipe when open. Of course this will would now make the mod a bit more complex to reverse and I have yet to try it due to still being under the warranty coverage. Sent from my iPhone using Tapatalk

I believe the 6.2 has actual resonators which have to be cut out. Sent from my iPhone using Tapatalk

Here you go Swiftks! I think were in the same situation but i think it should be fine. I mean plenty of folks running 12”wide tires with no issues on control arm. Sent from my iPhone using Tapatalk

Check the thread of 35s on AT4 and TB...several running 295/70r18. Best tire size in my opinion with a 1.5 level. Thats my future planned setup. I have the level but Iam wearing off the duratracs meanwhile. Look into the mastercraft mxt...lightest tire and very aggressive looking. Measures out 34.25x12. Should rub as others are running it with no issues. Sent from my iPhone using Tapatalk

Those should be the dimensions needed. Sent from my iPhone using Tapatalk

They did this on my At4 on the dealership when they swapped the chrome caps to black ones. Small flathead screwdriver and bamm done in less than 5 minutes. I didn’t check if they broke the clips of the old ones but they didn’t care and neither did I. I got my black ones installed and all is good Sent from my iPhone using Tapatalk
