My shitty 02 z71 does that... NOT... I want one damn that thing ***** and gets

 

How bout driveshaft any vibrations? Or is it a 4x4?
My 14 2wd vibrates nasty at 102+ and alil at 55

 

His is a 4x4. My '11 is a 4x4 as well and many runs over 100 with no vibration....mine has 197k miles now and still smooth as silk

 

Yea 4x4 dont have ds problems since ds is shorter a bit ill prob do a 2 piece shaft down the road

 

i've got a 11 CC 4x4, had it to 134 and said enough on stock 3.42s. I keep it at 100 or less with 4.10s now. Swap to 2 piece hopefully this summer and ill run it back up again.

 

How did you get a 2014 6.2 with 373. They only come in 3.08 or 3.42. I tried to get a 6.2 truck with 3.73. GM wouldn't make it

 

The 3.73:1 ratio is standard on the max trailering package. Watching the tach in first gear I can tell how much faster it climbs than mine with 3.42's. Wonder what it would take to replace 3.42's with 3.73's in a 4x4? $$$ I guess. Front and rear.

 

I have the max trailering package you can't get s 6.2 with 3.73 no matter what option you chose. I tried trust me. Built a Chevy and a gmc. When you chose L86 it only allows 3.42

 

not according to the chevy and gmc websites. if you build your own and get the max trailer option it comes standard with 373. just did it. now if you have the trailer option on your denali that is not the max trailer option. can not get a denali with 373 from what i have read.

 

what i see too :tup:
