I run one from Elite Engineering on my sc'ed suburban, had one on my full bolt-on '07 Tahoe too. Not sure if the new engines have the same issues as the GMT-900 and earlier models, but it would be good insurance for a modded motor. IMO on a stock engine it is not necessary. http://www.eliteengineeringusa.com/pcv-oil-catch-can-and-standard-hardware-ls3-v8-camaro/

X's 2 on the pic. Never heard of GM putting a catch can on any vehicle.

Guys with the 2.5" front kits, can you post pics? Also what size tire are you running. Going to be leveling my Dads '14 this weekend with 2.5" front and swapping rear blocks to 3" and running 295/55/20's on stock 20's, but am considering 295/60/20 just think they will be too big and cause rubbing issues especially since he must keep the oem mudflaps. Thanks, all the trucks posted in this thread look great!
