I'm not satisfied with my front and rear bumpers and am look for something else.

Let me see your set up and tell what they are.
 
Similar design to the old savvy bumper. 6061 aluminum which is the only one on the market with that material that is bent properly, except the corner add ons are steel for more strength. Longer winch deck so when the stock sway bar is removed for an anti rock or swayloc the winch can be pushed further back. As stubby and high clearance as possible with the sides just far enough out to cover and protect an antirock or swayloc. All weighting 20lbs for the base, winch plate, and steel corners.

I’m am not soo familiar of which rear bumpers with no hitch are the best as I have and love my hitch but I’ve seen many people run basically a frame skin with tow points and the bottoms of the skin roll under the frame so it doesn’t have a sharp lip to get hung up on. I don’t know of any brands specifically so hopefully some one else who know will chime in.

Pretty sure there are other 6061 bumpers on the market. Just none that are built properly to deal with that material’s characteristics.

Only one I know of is ucf but last time I heard it was not confirmed being 6061 like the genrights were as 5k aluminum. Could be wrong though.
Edited the original just incase. I believe the struggle with 6061 is the bends and not just welding every time a bend is needed. If any of that is wrong though let me know.

Depends on your needs. Do you want full width, or narrow? If rock crawling, narrow. If not, how wide do you need? Mine is full width, mainly for on the road. It was made by a company called Olympic. I don't think that they're around anymore. But here's a pic:

That sounds about right.

What is the benefit of 6061 vs 5k?

I’m not a machinist so anyone who is can better explain or correct this so I don’t know material science but 6061 I know it as a stronger but harder to work with aluminum. 5052 (I think is the common 5k aluminum) is easier to work with and for bumpers specifically bending is a lot easier over 6061 (why other companies choose to work with 5052) but lacks the strength in high impact spots so you won’t see any skids made of 5052 but will often see 6061 skids because of that strength it offers but is still workable. 7075 i believe is even stronger than 6061 but is even harder to work with and I don’t even know if you can bend it so i thinks a cnc cut only material bc ive never seen a 7075 products that was not just a cnc out of a block.

Really nice bumper @Fluxor

Will you possibly offer corner guards that wrap around the outer bend and cover the lower portion a little bit more?

I ask because I wonder if impacts to the lower outside, similar to what my bumper recently took (below), could conflict with the 6061's bend radius limitations as configured?

Thanks for fielding my concern.

I currently have a Hooke Road full width bumper on the front and rear. The pictures are the best pictures I have currently. The front isn't that bad, but the quality isn't the best. The rear, the more I look at it, sticks out way too far. I don't want a receiver in the rear bumper, but I want it to have enough room for a set of back up lights on or in it and come around enough to protect the tub behind the tires.

For the front, I'm leaning to a stubby bumper. My requirements are a small winch guard (like I currently have) that I can mount a set of lights on and enough room on either side of the winch to mount another set of lights.

Well now to show and not just recommend, I have motobilt bumpers. With Black Friday they do 30% off which makes for a pretty killer deal. The front is the crusher bumper and is great but weights 3x the flux bumper with no real gain as I don’t plan on plowing dear with it so I will be swapping it for the flux. The rear is I think they call it the crawler bumper with a hitch. It sticks out a bit but I’ve never hit the hitch but I have hit the corners but never hung up on them. With some frame tie ins they’re crazy strong and I often put way too much weight on the hitches with crap on a tray. Don’t recommend what I’ve done, but they’ve held up well.

Bend radius limitations must be adhered to or cracking occurs. I recently learned more about the topic from the Wizard.

Also, 7075 has stronger mechanical properties than 6061 but costs more. Our AR lower receivers were always Mil-Spec 7075-T651.

If 7075 was necessary for Jeep armor, folks would be paying an arm and a leg for it rather than it generally not being an option.

FWIW, I learned about 7078 about ten years ago and it’s super impressive. IIRC, it was invented in Japan about 15 years ago. Its mechanical properties are similar to some steel (can’t recall which) but the issue is that it’s costly.

Historically, Savvy aluminum arm links were 7075 because of the increased strength compared to 6061
 
I could not decide if this was best put here or in the meme thread…in Asia this week for business and saw dozens of bumpers like this on small cars in Jakarta. Not sure what they pull with it but the design makes you wonder. This was one of the better looking ones, many just have a flat tab welded to the bottom surface!
