I have this ARB, probably circa 2017. Thinking about replacing with a Dissent to trim some weight. Anyone know what my ARB weighs? I'm guessing a lot more than the 65 or 55 lbs for the aluminum Dissent (original and low profile respectively).

It is a not a LC100 but you get the idea -- the TUFF bar is a VERY heavy steel bar. The steer which end up in the tray of the vehicle is no lightweight. The driver survived but not the steer nor the vehicle.
I have not had the severe experience shown in the first pic above!
I do have the
ARB Deluxe Bar for LC100 2002-2007 ARB Part Number 3413190 fitted to my vehicle as shown in the second pic above. This includes compatible mountings for the Safety Restraint System (SRS), alias airbags. Official ARB websites are unhelpful -- seem not to reveal weight information even to us locals!
Several times I have asked mechanics at Australian ARB dealer workshops what they think is the weight of this bar. The answers varied between
70 kilograms (154 pounds) and 80 kilograms (176 pounds) nett addition, after the plastic bumper and related attachments have been removed. This weight excludes winch, sidebars, sliders, lights, radio aerial etc.
The weight given by Amazon USA for the same item is
176 pounds (80 kilograms) – but maybe this is the shipping weight including packaging etc -- --
Amazon product ASIN B004LQGB4S
When I look around various Australian websites for different steel bullbars, the estimate of
80 kilograms (176 pounds) is most common – so that is the guesstimate I use when adding up the contributions to the allowed overall vehicle weight, called Gross Vehicle Mass (GVM) in Australia -- probably similar to Gross Vehicle Weight Rating (GVWR) in USA (?)
If someone on IH8MUD actually has weighed one of these things out of the box on bathroom scales, that would be really good factual information.
Aluminium certainly gives a big weight saving. I had a Toyota-supplied aluminium bar on my previous 2002 LC100 and had a few animal strikes with that bar – mainly mid-size kangaroos, maybe 50 kilograms (110 pounds) at around 100 kilometres per hour (60 mph). It was only just OK – a few marks on the bar, pushed it back towards the body a bit, not a big enough impact to cause airbags to deploy. I would not want to be travelling faster or hit anything bigger with that bar on that vehicle.
For me, reducing the risk of the vehicle being disabled in remote places is the main purpose of the bar – do not want the cooling systems, fan, waterpump, electrics, etc -- being smashed (nor the A750F transmission cooler nor the turbodiesel intercooler). When my 2006 LC100 came along, conservatism drove me towards the steel bar despite the weight penalty, just for a little more protection and risk reduction.
Ultimately, panel damage is acceptable to me – meaning that panels etc just cost money to fix. Damage to vital systems and immobility is unacceptable – meaning that being stuck with a disabled vehicle while awaiting rescue/recovery in remote or difficult-to-access places is no fun at all -- especially if family are onboard, even worse if there are injuries. Such an event would never be forgotten nor forgiven!!!
I liked the style of the ARB bar in the second pic above because the secondary bar which runs across the front below the lights creates a smaller gap, makes it a bit harder for an animal to fit through. So far, it has done the job.
That said, there are limits. Travelling at say 100 kilometres an hour (60 mph) or more and hitting a steer weighing say half-ton to one ton snoozing on a warm road or wandering around certainly will bend the vehicle regardless of the nature of the bar. It would be very, very lucky for the vehicle to remain driveable. The main purpose of the bar in that situation is to minimise human injury. The measure of success is all occupants being able to walk uninjured from the vehicle. Even worse is hitting a tall or jumping animal which comes over the top of the bar and through the windscreen – how horrible this can be does not need any description!
Here is a crash test of a LC200 – no bullbar, not quite the same chassis as LC100 but not that different, similar enough to give an idea of damage after crash testing against an immovable solid object at standard test speed 64 kilometres per hour (40 mph):

This TJM video linked next below shows a few laboratory tests on bars – then shows some field tests with steel TJM bars striking a 45 kilograms (99 pounds) dummy kangaroo at 80 kilometres per hour (50mph):

Toyota explains how it does aluminium bars nowadays -- more impressive than my impressions way back in 2002 – shows testing with a 74 kilograms (160 pounds) test dummy kangaroo but does not mention impact speed:

The point of this post really is to highlight starting with a clear idea of the purpose of the bullbar, then deciding on the type, material and most relevant design.
There is nothing wrong with aluminium bars properly made with the right alloys and thick cross-sections and used in the right circumstances, for example, where it is unnecessary to consider very heavy animal strikes.
It is worthwhile to understand the design and construction of any bar and whether and how it meets the owner's purpose.
Suggest be wary of an aluminium bar stated to be more that 30% lighter than the steel equivalent.
