Does your temp go a little bit above from where it usually sits ? When stepping on it or giving it throttle for a while ? But then comes back down quick?
I sent a message as soon as this went up 3 years ago. I had a RU-vid issue anyway this video in upstate NY was shared and a lot of people did this kit. My Denali was doing a lot of towing and never got it done and now with 66,000 miles and relatively clean figured now is a better time than paying $78g for a new one. Hope all is well!
Commenting a couple years late but what style kit were you running with the 2/4? Drop Shackles and rear blocks removed with drop spindles? Or rear flip kit and spindles?
