Some information on this kit that I figured someone might find useful.
Oil catch can location: the location of this catch can works on all 2019-current vehicles (1500 Sierra, 1500 Silverado, Tahoe, Suburban, Yukon, and Escalade) that came out of factory with a 3.0 Duramax engine (LM2 and LZ0). The location also keeps the catch can and lines from freezing in cold weather.
Hardlines: provide better longevity under heat. The route of hardlines over the turbo/exhaust prevents the possibility of condensation build up within the lines.
AN fittings: provide a better seal, better longevity over hose and clamps, along a fittings with it being more appealing.
