Aluminum bumper

That's lighter than a CBI.

CBI weighs 190#. Without paint...

I don't want the CBI dual swing out arms. Only one arm for the spare tire. The CBI looks under-engineered and over-built. Just my opinion of the website photo without better photos of one.

I'm hoping for an aluminum bumper that weighs less than 100#. Aluminum is not as strong or ductile as steel but it would be stronger than the OEM plastic pumper cover. Good enough.

You can't tow with an aluminum bumper. Pelfrey has no plans for anything but a steel bumper. Frankly aluminum has no place on a rear bumper. Just not enough of an advantage and too many downsides.

The CBI is 200 when you factor in the spindles before the swing arms. The CBI is probably the best bumper on the market currently. I'll give them that.

Thanks Isaac,

I hadn't thought of that. I plan to tow a teardrop trailer in the near future. about 1700# tops.

Anytime a bumper company either doesn't list it's hitch rating or says "not rated" that's kind of a clue.

Rarely am I actively hitting things with my front bumper, but I'll come to a rest on my rear bumper when coming off an obstacle, or scrambling up a boulder.

I get the appeal of the concept of an aluminum bumper, but it's not going to be as strong unless you really really buttress the hell out of it, and then your weight savings and cost savings become almost non-existent.

Steel just makes the most sense, you just have to be prepared for how it affects the vehicle and get the right springs.
 
even with significant weight reduction? curious since I still plan on a swing arm rear bumper, but planning to leave the inside mostly unadulterated

It won’t get significantly lighter to the point where it’ll impact my spring choice.

Let’s say it’s even 100 lbs lighter, which it won’t be, it won’t change my spring rate.
 
Getting closer!

Gets primed and painted tomorrow. A few dents pulled out, and then outside of a few parts to replace/repair, it'll be de-baja'd.

Do you think the tires are going to tuck up into the fenders at stuff? Or are you going to need to trim?

We've already cycled them at 10PSI and they won't touch the fenders.

The driver side needs to have about 3/4" of preload added now that the springs have settled.

You don't need to have ridiculously high cut fenders, you need to have your suspension tuned properly and bump stops set correctly.

Well yea you can set your bump stops to engage at ride height and then never have any rub issues, then they act as a bypass shock. life hack. you're welcome. Trololololol:usa2:
