Added weight with aftermarket cage

Would some of you mind commenting on about how much weight an aftermarket cage added when you put one on your X3? And if manufactures want to post about what their cage adds weight-wise, I would appreciate it. Thanks.

DOM tubing is pretty popular with the rockcrawler guys (jeeps) but heavy, chromoly is lighter and quite expensive, i'd be curious to know what materials the cages are being constructed of.
im ok paying good money for good quality but i sure dont want an overbuilt cage with poor quality metal weighing down the machine just to say its safer

DOM tubing is heavy, chromoly is lighter
Mild, DOM and 4130 all have the same density. A tube of equal dimensions will weigh the same for all three materials.

This urban myth is due to the fact that 4130 is stronger, so you can use thinner walls to achieve the same strength.

If I need to, I will call, thought this out in the open might help other readers. I agree the safety will outweight the negative of added weight, but if I can keep that to a minimum while still being safe, all the better. I know the EVO guys have the S3 cage and it held up in a big wreck supposedly, but I have not seen any pictures. What I have seen pictures of is the stock cage folding, now under what circumstances that happened, I do not know.

I'm will tell ya this much the only damage to the S3 cage was the aluminum roof and the right rear back bar since that bar only attached to plastic and is not tied into a bumper.

70 more or 70 total, if total weight, how much is the difference from oe

I bet the weight difference between a stock cage and aftermarket cage is less than 20lbs. If you get a cage with the integrated rear bumper, then it would obviously be more, but I would venture maybe 40lbs more.

Depends on how much extra tubing you are adding compared to the stock cage.

It sure looks that way. They seem to suffer much more damage than the previous version.

I think the previous version with a full B and C pillar added a lot of strength. Tim

That's really to bad as canam having a good cage was a nice feature . Now canam's flagship goes faster , has more power but the driver is not as safe . Now they are like popo , forced to buy a cage . If you have a 5 point belt system on you can't have the cage flatten out and hit you . Cage builders will be happy as now it's a necessity .

Nobody is forced to buy a cage with any of these SXSs, just have to know that the stock cage is not going to fair too well in certain types of accidents. If you flop it on its side, the stock cage will be fine. You endo and slam it on the roof, I sure hope you are wearing a helmet and have harnesses because the cage is coming toward you.

Also, not all aftermarket cages are created equal. You really want to use someone that knows what they are doing. There is more to it then throwing some better material tubing together. There is an art to knowing how to make a strong cage.

You guys make fun of PoPo and other brands, but Can Am is really not offering you anything stronger in the cage department. Don't be fooled because it has larger diameter tubing.

The tubing size and material quality in the x3 cage is fine. What is not fine is the design. There is zero triangulation or support where you need it the most, at the A pillar where that big gusset is supposed to somehow take the place of a down tube. The steeply raked, "cab forward" design looks cool but isn't strong. What you want is a cage that isn't going to collapse when you land upside down and without vertical support that's not going to happen.

this all sounds a bit negative, i think an upgraded cage is needed for people that are driving fast, i don't care what your driving and how good your safety gear is, if you drive it fast you ARE CHOOSING to take a risk of your own safety. can am had plenty of rollovers during the demo period and none of them looked completely collapsed. i realize these things weren't built for the average cruise guy but to say that they are complete crap is a bit of a stretch

I agree with you. There isn't a degradation of cage here IMO as newer vehicles are coming on line. But the newer vehicles have more capability than they did in the past and are going at faster speeds. In the same vein, there is nothing stopping somebody from buying a 1000cc sportbike and riding around on it in shorts, flip-flops, and no helmet. Its a store bought vehicle that goes insanely fast and if you don't respect that and use it stupidly then you are going to pay the price. If I wanted to go super fast on a sport bike I would protect myself with a good helmet, leathers, boots, and spinal armor. Likewise, if I wanted to go insanely fast in a UTV I would protect myself with a better cage. You can safely drive an x3 or any other UTV with no helmet and stock belts as long as you drive it appropriately, which isn't right foot mashed through the floor over huge whoops and rocks or over jumps.

I do not know what happened in the worst picture that Mega posted (first one), but one of the lesser ones he posted was a simple flop on dirt. I saw video of it and the guy was doing donuts (dumb I know) and put it on its side. The folding of the A pillar was much worse than I had expected. I remember being quite disappointed since I was hoping to get away with leaving the cage stock. It stuck in the back of my mind and I didn't really forget about it. Then more recently, this past weekend, I was decelerating in some sand dune bowls and I glanced down to see 65mph. That means I was probably over 70mph regularly when we do some aggressive dune runs. Coupled with the fact of the first picture Mega posted, I got pretty concerned. It is one thing if I am only putting myself at risk, but if I have passengers, I don't know if I would ever forgive myself if someone else got hurt. It was a lot different on a slow wildcat, this thing tuned is pretty damn fast and a small mistake on my part could mean a big wreck. If I wasn't such a damn speed freak and could keep my foot out of the gas, the stock cage would probably be fine for me. But since I cant help myself and love the acceleration and speed, I am shopping for a cage.

We are building a race car so have spent a bit of time on this, we built the main hoops out of Cold Drawn Seamless Mild Steel Tube 44.45 x 2.6mm (1 3/4"Ø x 0.102" wall) this weights in the region of 2.6kg per meter (I think that equates to 1.9lbs per foot). We built the rest of the cage out of Cold Drawn Seamless 1026 Mild Steel Tube 38.1 x 2.6 (1 1/2"Ø x 0.102" wall)


Main hoops = 6.4m x 2.6kg of 44.5 = @17kg = 37.5lbs
Cage body = 32m x 2.2kg of 38.1 = @70.4 = 155lbs


Our cage weights 192.5lbs - but this is a comprehensive cage, we have changed a lot of barwork and added in a lot more, I think the cage should have a cross brace behind the rear seat, we race with lots of trees around us and if you ended up backwards at 90mph into a tree, there is nothing save a bit of plastic between you and your maker. As a minimum I also think the front seat bar should be changed as there has been half of it cutout to clear the tailshaft. Any steel that is welded to the existing chassis has a radius steel (4mm) plate to spread the load. As a side note I’m not a big fan of chrome-moly and would never race with a cage made out of it (I understand people have different opinions on this, my life = my choice budget was not a consideration in this decision)




So having said all of that, these are my thoughts on a bolt on cage based on the steel we used.


Main hoops = 6.4m x 2.6kg(per meter) of 44.5 = @17kg = 37.5lbs
Cage body = 5m x 2.2kg(per meter) of 38.1 = @11kg = 24lbs


The stock roof cut-off weights 20kg (44.5lbs)


So based on that there is only around 17lbs difference between stock and aftermarket. But if the cage manufacturer is using a lighter grade of steel it will (obviously) be less.

This is the cage I would do.

I can give you a weight on ours Monday. Feel free to give me a call if you want to go over materials and thicknesses and what we have to offer to save weight

Oh yeah. We do a lot of them.

We have a found safe ways to cut weight off of them. A lot of guys run extra tube for looks but it adds weight. We do that on occasion for people but I'm all about performance and added safety

Give Alternative Offroad a call. Great place to deal with and can answer questions about Fabwerx cage.
