I am in the final phases of creating a new rear bumper for my Tracker. There were no rear bumpers that suited me. It incorporates a rear Warn m8000 lb winch, rear fog lights for backup lights, rear protection for the spare tire/back door and a 2 inch receiver. Full size mock-up had been made and fitted. It has adjustable mounts so it can be adapted to no lift, 2" Lift or 3" lift. It will be CNC plasma cut from my CAD drawings then folded and assembled by welding. The bumper basically fits in the dimensions of the factory bumper even with the winch except for the bar. I used the style lines and bar size of my Shrockworks front bumper so it would match that bumper. I kept begging Shrockworks to build a Tracker rear bumper but my last email said they will not build one.
The rear door protection was incorporated because I am often wheeling in woods and hills. Backing into a tree stump or rolling back down a hill into a tree could cave in the rear door and blowing out my rear hardtop window. Someone behind you might roll into you on the trail and again without the protection cave in your door. Someone could actually push you from behind with this bar. Basically without the bar your spare tire becomes the bumper. It will not affect approach or departure angles. I probably will mount a D-ring with 1/2 steel plate to the bumper under the center support but have not done that yet in my CAD drawing. The rear door protection bar is only sticking out 4" which is 1/2" further than the 31" tire and also could protect a jerry can on the rear door as well.
I am installing a rear winch to increase recovery possibilities. 3 out of the 4 times I needed winched was from behind. My front winch was not much use in the picture below. WIth a rear bumper I can help stuck buddies on a tight trail without turning around. If no winch is installed you would have 28x7x7 space for a large air tank.
The 2 inch receiver has safety chain holes in the bumper surface rather than a separate plate so there is not a safety chain plate to catch rocks on like most recievers.
Let me know what you think. Not too late to make changes.
