Looks like a custom Bubba-job to me. You won't find my bumper on another Jeep either since it's custom.
The only things I can think of that "R" stands for is Rugged Ridge and Rough Country.
Personally I would ditch your front bumper and go with something more like mine which is 3/8" thick 6"x4" structural steel beam. Also what is the point of the vertical rods on the ends of the bumper? As for the rear I wouldn't go towing anything with that hitch or using it with a recover hook unless the bumper was tied into the frame, you'll mess up your rear frame horizontal support and possibly twist the frame.
Also you might want to get 2 tow hooks to mount on the front bumper through the bolts that tie into the frame.
I have my suspicions that theyre custom, especially the rear but I cant figure out that branding on the front. The front bumper is 3/8" thick. Its pretty hefty. I'll have to look at how the rear one is set up. To see how that hitch set up. Ive looked through every companies stock I could think of with an R but they don't have older items and might have changed the logo.
95 YJ, 3/4 ton MJ axles, 4.56, Detroit lockers, Posi-lok, 35x12.50's (sometimes 44's) on Procomp 15's, 6" RC springs, 2" Shackles, 6" Body lift, SYE kit, custom drive shafts, customs bumpers, Rampage Trail top, Rhino lined inside and out, Optima Red Top, 2x KC Daylighters, Kicker speakers (soon to be upgraded), Blistien front shocks, Walker Evans rear shocks, Quick disconnect links
Just because it has a logo on it doesn't mean it was made by a company. Anytime I build something, I always put my mark on it. I've built everything from Kitchen cabinents to bumpers & all had my makers mark on them.
Those are some beefy bumpers & will last longer than the Jeep.
