Bull Bar Crash Engineering

[gaijin]

Ok…because their bumper and slider and how they connect looks just like ARB.

It's an Australian thing...

ARB sticks out more , you can‘t go wrong with either , ARB will hold a bigger winch a lot easier , ARB is a foot forward mount and TJM is a foot down mount is only limitation , I have seen a T13 modified to fit a foot forward .
The TJM is a no cut and the ARB has the wings of the stock bumper .
I like the look of both , I have had ARB in the past , the powder coating was not the greatest , neither was TJM at the beginning have improved and are offering a 3 yr warranty .
I liked the push bar uppeRFS followed the grill angle on the TJM , I think the mounting carriage on the TJM looks to be a little beefier .
Figured I would give them a try after seeing a few on here .

The ARB mounts the winch foot forward on the bumper itself, the TJM mounts the winch on the bumper support foot down. TJM also has a cut version of this same bumper as well with the same bumper support winch cradle. I mounted the Zeon 12S with no problem. I relocated the controller under the hood by my Aux battery. I will have some pictures of that after I clean it up a little.

I will most likely do a Dissent rear bumper. I have never had any rubbing with this tire and wheel combination. The Icons have a 25mm offset. I don't think I would have a problem going to the next size up and most likely will with the next set of tires.

Thinking of going Ridge Grapplers 295/70r17 which is a 33.31 x 11.77 what UCA are you running

I have SPC.

Cool bit I came across. TJM just went way up in my book seeing actual impact analysis and engineering going on behind the scenes when they create a bull bar. Doesn't hurt that the bar on Shauno's new 200-series build looks great.

It would be interesting to see if there is anything out on the web that shows what ARB and some of the other do also. I had seen the Roo part of this video and a little other stuff that TJM has done.

This reminds me of a comment the founder of maxtrax made during an interview I watched. He came to the US and enjoyed a suspension (don't remember which one, but it was a big name), so he imported a setup to Australia and it failed in short order - it's a different type of environment with different demands.

Yes and yep. Australia is very strict with every off road aftermarket part and modification. It must meet or exceed OEM standards and pass government crash tests for things like bull bars and bumpers. Wheel spacers are not allowed on rigs registered to drive on tarmac. If you use them you better be towing it to a trail on a flatbed. Vehicle weight. Don't you dare go over those numbers. There are things you can do to increase the max weight but again you have to have it done by someone who is licensed and they give you special stickers with the new adjusted max weight. Same goes with vehicle height regarding lifts. And the police actually do check and know what to look for. They have a lot more of them down there and really do need to regulate them. People have a tendency to over do certain things. I'm sure if we had the same percentage of modified vehicles on the road here we would have the same or more regulations regarding part quality and modifications.

Great thing is if you buy a bull bar from AU you know your parking sensors are going to work, air bags are still going to work like designed, it will crumple proper in an accident ect. And they build parts for folks that use them every day as a 4x4 DD. The majority of americans are weekend 4 wheelers. Those people not so much. They won't purchase something that doesn't last and leaves them stuck on the way to work.

Here is a video I found on the engineering in the ARB bumper.

Here is a interesting article on TJM bumper development.

in North America without the bar critters tend to head for the back seat though the windshield, or at a minimum take out the radiator.

I will let you know. I just finish installing mine this past weekend. Just some driving around town so far. Don't have any data on MPG or how it feels on the interstate yet. I still need to adjust my BP-51's for this addition.

I am curious about the added wind noise at highway speed and Amy change in driving characteristics?

Noise is subjective. I have an LX and it has more sound proofing - I don’t hear a thing.

Handling is physics. You are hanging a few hundred pounds (depending on winch and light setup) forward if your front axle. How this effects handling will definitely depending on your truck. My LX just adapts to it - for an LC you’ll need to compensate with spring rate and pre load or else your truck will feel very undersprung in the front.

Yes I took a science class or 10 and so get all of that… sounds like I need to trade for and LX!

No change in wind noise. Obviously it did handle a bit different than before I put it on. Feels normal now that I am adjusted to how it feels.
