I couldn't find any info on the Tibus Off-road Engineering website that pertained specifically to the bumper. My best guess it's a custom build for that truck to showcase their cool dual motor winch. The bolt on portals are very cool too.
Thanks for the replies guys. Too bad it's only for the Defender and really too bad it's $1600. That Tactical Rover bumper looks pretty nice, I might look into that more. Thanks again!
