almost 100% oem.
complete audio system, garmin gps, console adapter, roof, mirrors, winch warn 4000 front pre runner bumper, rear bumper, spare tire, spare tire holder, jack system, front and rear arm guards, interior dome light, rear bed liner, plus the 6inch bed extension and the large 3 pack storage containers that I switch between that system and the bed liner depending on where and how im riding. may be missing other things but that is easy 4G, maybe more now that I think of it...lol..I also installed it all myself or you would have paid a dealer every bit of 1200 to do it. I think I have 22hrs in the full install. took my time, read things twice. not a single issue. oh yes, also got tow strap system, snatch blocks,etc.
