New option for 4th gen sliders - potentially

[BackOff]

true, BUT, when you're done mounting them, just throw a quick bead of caulking. You also have to remember, the fram has LOTS of holes anyway, water will get in the frame anyways

I was thinking rust between frame and the slider mount plate.
RCI has a very similar setup and seems like i have seen at least one other like this too, with that full frame mounting plate.

Just with all the poor old rusted out 4runners i have seen on this site, adding a potential rust zone...
y=mx+b thats not aimed at you.

Might be better to just spray some kind of fluidfilm in there than to try and seal it with caulking, that might just trap moisture.
Maybe clean and paint the frame too? Before install.

I don't know anything about engineering.

Agreed.

You could have fooled me about that design not being yours. You have a prototype on your truck, the original CAD file and were explaining the different design features and the reasons why it could not be done in any normal, non-janky way.

How about you remove it, fix the design so that it does not bear the entire weight of the truck on 5 m10 nutserts and then post pictures of the newly updated model.

Little life tip for you-
Nobody cares how smart you are (or at least how smart you think you are). If you're a jackass, people probably wont listen to you. So, you might as well keep your thoughts to yourself (for my sake and probably most people here).

I'm not planning on responding to you because you don't seem like someone I can have a constructive conversation with, so type away all you want.

Agreed.

Yeah, I gave the full back story in my original post. Feel free to go back and read it. Maybe you'd understand it if I wrote it out in crayon.

Condescending and abrasive is a helluva way to go through life. I don't know how many kids you have, but I'll bet you have at least one who no longer speaks to you. Weren't therapy sessions a mandatory condition for parole? Hope you get the help you need.

Got them mounted up today and I'm very please with how they turned out. They tuck up really tight into the underside of the truck providing maximum clearance. I ran some of the objections by the fabricator who designed these and he chuckled. We might arrange for a drop test. I'd be happy to let them use my ride to do a video demo like I've seen some others do.

I can't answer all the technical questions, but I do know they're DOM tubing .120 wall. Price point is $748 naked. $180 for powder coating. Shipping by zip code.

Those look very nice. Your Rig looks great man. They are like 10 minutes from my House. Finally a place Local and Close to me.

And if you are looking for the real deal which isn't a fake copy made from the correct thickness of metal which weighs less, is 5x stronger and doesn't cost an arm and a leg and actually fits on the truck without bending and rusting then click here:

2010-2020 Toyota 4Runner Rock Sliders

Available for the 4th gen as well by request. And no I don't work for All-Pro.

While the approach may be a bit abrasive, I do believe there are some good points here. It is important to protect a consumer from poorly designed products, especially if there is possibility of damage to the vehicle with normal and expected use. I would hope that the gentlemen designing these sliders does have a degree in engineering, and if not he has years and years of heavy duty OFF ROAD experience watching designs fails under stress and many, many revisions before offering a product to the public.

At this point, they look OK, but nothing unique and that isn’t already offered by more reputable manufacturers with much more experience in sliders. Also, what’s with the bolt and piece of metal on the bottom of the frame rail? Isn’t that just asking to be sheared off?

I believe the two bottom bolts on the lower part of the frame are a relatively simple attempt to relieve the torsional stress of the arm bending upwards and warping the full length mounting plate away from the frame at the 3 legs. Note that the factory m10 fastener points are not located in the shear zone of the surrounding metal near the 3 welded on legs. Additionally, the gussets have minimal effect on vertical rigidity as they are not attached to any significant structure besides the undersized plate which only has 5 total fasteners to begin with. I find that attempting to "slide" over a rock with downward facing plates and 2 bolts sticking out is counterintuitive. The bolts may catch on a rock and spin the truck along its vertical axis and dump it on its roof, injuring or killing the driver and other occupants.

That may be the most decent thing you've ever written.

As far as your assessment goes - dunno - may be right. I agree with the questions about the two bottom bolts. That's an entirely fair objection. I do know they have some very experienced and respected fabricators. Word of mouth and reputation go a long way toward building a following in the aftermarket off-road business, and I can tell you the most difficult part of Jeff's business since he went full-time with it last year has been scaling to meet demand for his work and his products. He's always booked 2-3 week out for appointments to get anything done, and they've decided to no longer do ad hoc, one-off fabrication of anything. They have so much demand for their TRD Pro lift kits, bumpers, roof racks, etc that they can only focus on what work and parts they can sell repeatedly.

Which is how the project for these sliders made their product list. He began selling them for 5th gen 4Runners and Tacomas earlier this year and now everyone local wants them on their rigs. If you visit his Instagram page you'll see nothing but comments from followers wondering when he's coming out with "this" or "that." All the of growth of his business has been completely organic, and to me that speaks volumes about the products, the quality of their work, and their customer service.

Solution:

Instead of making 2 tabs which protrude off the frame, why not make the bottom of the flange full length and install 3 stainless rivnuts in a triangulated pattern directly on center with the 4 support legs in addition to the factory nutserts. The stainless 3/8 rivnuts each can handle a static shear load of 1520lbs. Since the rivnuts are 90 degrees to the axis of weight, a high percentage of the load on the rivnuts will be shear and very little axial pull. To stop from catching on a rock, the holes are chamfered for flat top countersunk stainless allen head 3/8 bolts.

Design is free for anyone who wants to use it. Editable Solidworks files available upon request. I realized I was kind of being a punk by offering only problems and no solutions.

I appreciate the change of heart man, this is the kind of helpful attitude that helps me and others learn! You sound like a smart guy, glad you could contribute your knowledge towards a mutual design improvement. I like the insight on shear vs axial loading of rivnuts under the frame, I always enjoy learning along the way.
