Here you go:
So let me phrase this not as "here's what I don't like about the CBI. If Pelfrey decided to not release their rear bumper I wouldn't look at my CBI with disdain. Rather I'm phrasing this more like "here's what I think Pelfreybilt is improving upon" if that makes sense.
You are correct, the bumper isn't for sale yet on Pelfrey's site. It will be in a few months. The dual swing arm that you've seen teased is *MY* bumper. That's specifically the one I'll be getting. And it's also the bumper I've had design input on. When Tyler and Satin came to me they basically asked me what I liked about my CBI, but stuff I'd like to see added.
I'm on my second CBI bumper, and I think frankly a single swing arm really has no good defense especially because it increases weight on each spindle, and makes opening it with a trailer impossible.
I think the latching system on the CBI is...not so great. I know I'm only one of a handful of people who've broken there U-bolt components, but when it fails...it fails bad. It basically sheared off while going through Baja, and almost knocked us off the road as the weight of the 35" tire caused the back end to kick out bad to the right while going fast over whoopdidoos.
Some of the biggest areas for improvement are how the arms work, latch, and interact with the bumper itself. If you've seen my CBI I've made HDPE plastic contact pads, as I really don't care for powdercoated metal on powdercoated metal as far as mating surfaces go. It always wears through and rusts. Maybe this is fine in drier environments like Idaho or SoCal, but up here it rusts bad. The Pelfrey will have delrin on delrin for all mating surfaces.
Lights are built specifically for integrated Baja Designs S2 flush mounts, which allows them to tuck the bumper up for a bit better clearance at the 5 and 7 o'clock portions of the lower portions of the bumper. It's also a no cut bumper, meaning you pull the original bumper completely off, and bolt this new one in.
It's going to be steel only, I could go on and on about aluminum vs steel, but for a rear bumper, it needs to be steel, especially for hitting shit and towing stuff.
The biggest thing is that they did away with spindles. Each arm uses two heim joints, this mean that each arm can be removed fairly easily, but it also means that the arm is supported along a greater amount of vertical length. The goal was to create arms that were more rigid at the base, so that vibration wouldn't go further up.
The bumper will support up to a 37" tire, however that's a little unrealistic given fitting 35s is already a challenge on the vehicle itself. The tire will sit directly dead center on a depth settable angled mount, with whatever accessory on either side of the arm.
The latches are just awesome. It's what Pelfrey has taken the most time to design. Most bumpers use the off the shelf latch, and those are the weakest point on the CBI, SSO, etc style bumpers.
Again I like what CBI has made, my biggest areas I saw improvement on were the latch, and how the bumper locked open. The climbing pins on the CBI are less than great. I think CBI knows that, as the series 200 LC bumper they are now making, and was seen on the Expedition Overland bumper for their 200 now uses a flat style plate that you have to purposely pull up on the pin, move the arm, and let the pin drop into. The current climbing plate/pin system has a tendency to smash into the angled metal shelf on the spindle, and divot out the material since it's steel on steel.
Basically, if you need a bumper for the next 2-3 months, go CBI. I haven't used the Pelfreybilt design yet, I do know is that all the hard work on that design will be translated into updated bumper design for the Tacoma, Lexus GX, 4th gen, Tundra, etc. This is one of the most complicated bumpers anyone has done for the 4Runners, but it should be great. I hope.
As a result they are giving me the opportunity to use it first and figure out what works, what needs changing, etc. I've lived with the CBI for 2.5 years now, and I tend to be critical not about what I dislike about things, but what I see as improvable areas.
I won't be the kind of person to go up to CBI bumper owners and say "ugh poor choice on armor." That's not my goal. Rather it was to say "That CBI is a good bumper, we just made something THAT much better."
