Expo style rear bumper build for a Sliverado 1500 (GMT-800)

A friend of mine works as a rock climbing/mountaineering/canyoneering guide, he spends most of the year living out of his RCLB Silverado 1500. His rig is pretty simple, all stock, sleeping platform with memory foam mattress in the back along with some built in storage. Hes really been wanting to get his 4 5gal Scepter cans and bicycle out of the bed to free up some elbow room. We decided a rear bumper with 4 can carriers and a bike rack was the best way to do that.

The main 2x4 and all the hitch parts are made from 3/16" steel.

The brackets that tie the hitch to the frame are also 3/16" and have 5 bolts per side. I reused most of the stock bumper and tow hitch hardware.

Working out the shapes.

Since he doesn't do any hard core crawling and isn't worried about it taking direct hits from rocks we decided to skin it in 14G to save some weight. Tread plate for the horizontal surfaces and flat plate everywhere else.

Tomorrow I'll get to attaching the spindle, building the basic swing out and attaching the can carriers, no pics of those yet I forgot to get some today.

Does he have or plan a rack on top of his shell? If so maybe some oval toe holes put toward the bumper ends to act as steps might be handy.

Nicely done, clean and efficient design.

Thanks for the compliments guys.


Really good looking bumper. I like how you kept the factory looking "pocket" where the license plate goes.

Thanks! We wanted to keep that for a step and I like the aesthetics of it as well. Its kinda a chunky version of the stock bumper with bobbed ends. We bumped out the top section of the bumper a couple inches as well to make it easier to stand on. He mainly accesses the sleeping quarters with the tail gate up thru the back hatch so that should make crawling in and out a little easier.

Thanks for the compliments, his shell extends above the cab a couple inches so no plans for a rack above.

I had thought about that, I like that feature on the newer Chevys. In this case the swing out spindle runs the full 4" down the main tube and the skin kinda comes to a point there on the end, the step would have to be on the rear face and I think it would look kinda awkward. The step pocket needs to wrap around the side a little like on the oem bumpers I think.

I have a 3rd gen 4Runner that I picked up cheep a couple months ago, Ive been planning a rear bumper with swing out for that thing and it will wrap around the sides to the back of the rear tire opening. I think steps would work awesome on that since I'm also planning to put a couple kayaks up there eventually.

More pics soon, just lots of boring welding and grinding today.
