Yup, mine didn't do this till I did a burn out. Now when I hammer the gas, I feel a vibration. From what I've read online and going thru posts on other sites, these drive shafts are crap. Few guys replaced them with a stronger 2 piece shaft and all the vibration goes away. IM going to order one soon and see how it rides. Mine is a 2017 6.2 with 8 speed, plus a 6" lift and 35" tires. Got a custom tune and went to test it, did a burn out and now vibration issues.
Anyone try these on there GM yet ? I am thinking of getting a pair to run with my 6" Fabtech. Curious how much better it improves the ride and if you can gain some more lift with them. At $999 and adjustable, would love to see a comparison to the Fox adjustable coilovers.
Hello, Was looking at these ebay power folding mirrors. Anyone have any experience with these ? I currently have a 2017 LTZ with blinkers and power fold feature on stock mirrors. Curious if i would need any type of harness to make these fully function. https://www.ebay.com/itm/2014-2018-Silverado-Sierra-POWER-FOLDING-HEAT-Extended-Tow-Mirrors-w-LED-Signal/302923745976?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649
Appreciate the feedback. I am currently running a Edge CTS2 tuner to calibrate the oversized tires and improve mileage. It’s working good but the tranny is annoying some days. What is your plan for a tune ? Wish Black Bear could do it.
New member here. I have a 2017 Silverado with 6.2 and 8 speed. Trifecta is claiming they can tune the 8 speed, but no one else can just yet ? Mine has about 38K miles on it now and the down shifting is ridiculous. You can hear and feel the clunking from 3rd to 2nd to 1st most every time. Sometimes I dont feel it at all. Dealer says that is normal, which I cant believe. I am willing to try anything to make this some what better. Can anyone give anymore feedback on how there tune is going on the 8 speed ? Has the downshifting issues disappeared ? I'm also concerned if i have more issues with the drive-train and need to return to the dealer, will they know I have had a tune done if i reload stock tune ?
