Have an 18” crewcab 5.3 with cai and custom exhaust. I really want to price out a turbo build rather than supercharger. I’ve heard good and bad about the On3 kit. Currently the only “kit” that I have found available for the 2018. Anyone have some input? I’d like to keep the trans stock and possibly get driveshafts as I’ve heard they can be an issue. 3.42 gears and 4x4 TIA
