Who makes aluminum sliders?

... They're pretty close for " real world " uses..

 

Yes. I know what they are. Not that it matters for this discussion.


Idk why you are taking exception to everything I’m saying. At one point I’m pretty sure they were using .065”. It’s doesnt appear they are now. Either way, there still is no benefit to building rock sliders from 4130. You can believe what you want.

 

They never used .065" lol. I'm just tired of reading all your posts defending your choice to use DOM and slamming the use of 4130. I believe what is tried and proven not what your calculator says. Like I said I've been fabricating this kind of stuff for a long time and have first hand knowledge of both materials characteristics. Point is 4130 is stronger and more expensive, that sir is a fact. You don't think it is worth it and that is an opinion.

Cool video. Dropping truck equipped with sliders made of diffrent material on a rock.

 

Ok man. Like I said, believe what you want.

 

Good attempt. Personally I think they should have used something more consistent for damage than the rock, as it seems it hit in different places for the the different sliders. Also they don't offer a fair comparison of square to round tube sliders since they are different diameters, so of course a larger square tube will hold up better than a smaller round tube. It does a good job of showing how not to mount to the frame too. Probably why the comments are disabled.

 

I'll hit up Jeff Geiser at Geiser Bros and let him know he is a fool for building his Trophy Trucks from 4130.

 

Nah. Different application. Makes sense for a roll cage. The design benefits from 4130 advantages.

 

I’ve read a lot on the DOM tubing before I went with my sliders, not much on 4130. Why do you say 4130 is superior?

 

..

I just wanted to add something to the conversation. Since I’m not a engineer and know nothing about metal. I did however purchase my sliders used from NASA. The are made of titanium, taken off the lunar rover prototype. At least that’s what the craigslist ad said.

 

And so do sliders.

 

No. The engine can hack the sliders w/ ease. This just doesn't make sense. And for whoever said they want to pay 2000 for alum. slider because they don't rust is crazy. My sliders see salt year around and they don't rust. And if they did..for 2000 I can by 3-4 sets of them.

 

Figured we should at least link the original discussion:

Btw a vnotch and % yeild is way more relevant than tensile here, in regards to both 4130 and aluminum.

 

Interesting discussion from an engineering, cost effectiveness outlook.

One has to wonder under what circumstance sliders from DOM would fail and 4130 would not, with everything else being equal. After all, that would be the reasoning for using 4130, would it not? Then, what is the cost ratio of the two? If I'm getting a 3% increase in performance at a 200% increase in cost, I fail to see the point, but if I get a 25% increase at 100% cost, I can see the advantage. What's the cost/benefit breakdown on the 4130?

 

It's not a 3% percent increase though. That simply quoting the spec he loves to throw out there.

4130 will take rock hits better and for longer, less likely to dent or get rack rash, and is less likely to deflect allowing the slider to contact the cab.

 

OK, so what is the %? I was just throwing those numbers out there as an example of cost/benefit analysis. We've all seen many pictures of DOM sliders after wrecks that took a lot of punishment. What's the real cost/benefit ratio to 4130? Better isn't always better. I want to pay for real world advantage, not theory. Same OD, same gauge, same design, what's my real world increase in strength?

 

It's not that simple if you want to compare slider A made from DOM and slider B made from 4130. 2 different designs, different mounting ect. I'm simply saying if you want to build the best slider, then 4130 would be my material choice any day. Cabs are not cheap, Tacomas are not cheap. I look at it as protecting an investment.
