My custom Rock sliders 56k warning

[JohnnyU]

In this particular application, I have seen many more round tube sliders bent than I have square tube sliders.

I'm using 2"x2" tube for my sliders/rails. I haven't yet determined the wall thickness, but I'll probably just use 0.120" due to the design.

well if it not DOM or chromoly, i can see it bending.

Tube dents easier then box does. no matter what its made out of. I just started my sliders using 2x4 3/16th and 2x2 3/16th for the legs (there will be 4 even though only 2 are pictured)

your crazy! lol!

give me the same wall thickness round tubing as rectangular tubing and i promise you the round tubing will hold up better.

the reason your rectangular tubing is stronger is due to the fact that it is .250" thick rather than a .120" wall thickness round tube. the arc is the strongest stucture and has been proved centuries ago.

3/16th round tube and 3/16th box neither are going to have any problems under a ranger. Thinner wall stuff box will hold up better. Box resists denting and bending better then tube does. Ill have to find the actual science behind it, (have to break out a strength of materials book) but same wall tube and box the box wins. Example a peice of 2x2 box steel with the same wall as a 2" round tube will be stronger.

Go price out 15 feet of 1.75 or 2" 3/16th wall round tube, and youll see why box is better in not only strength but price also.

Until a bend comes into play (such as a roll cage), rectangular tubing is superior. Once you add bends into the equation, the opposite is true due to the geometry of the round tube through the bend compared to that of the rectangular tube.

for my sliders im using 1.75 DOM .250 wall with 1.25 DOM .120 wall inside the 1.75 tube. We will see how that works out.

metal bends!! its just a fact that weve all proven threw past experience.

just keep your tires in the right spot and you wont have to worry about bending those rock sliders.

the sheer weight of the rig will bend anytype of metal if its not supported and welded in the right spots

who cares if sliders get dented, bent or worse, the reason there there in the first place is to protect the rest of the truck

AFAIK boxed steel resists bending loads better normal to its faces due to the larger amount material and its walls being perpendicular(at a right angle) to the load. Round tube resists bending in all directions more effectively because of its symmetrical cross section, whereas a box tube will be more likely to fold if it receives a hit not normal to one of its faces (like a corner hit). If you're concerned about a corner hit, you can always cut a strip of plate the length of the slider and the width of the internal diagonal cross section of the box tube (2.65-2.66 inch with a 2"x2"x.120" box) and tap it in. That would strengthen it up quite a bit, tho only on a single corner.

That said, I think square tube looks better as it can be integrated into the lines of the vehicle better. I like the look the OP went with, very subtle.

the arc is the strongest stucture and has been proved centuries ago.

Arc's are strong assuming the bases on either side are fixed. Arc's work by spanning a gap and distributing load from the middle of that gap to the base of the arc on either side. With a tube you have essentially two arcs attached to each other with the bases free floating. when one of these 'arches' receives a load it distributes that load to its base, which is just another arch. The result is if the load is beyond the materials yield strength, the 'base of the arch' or the sides of the tube relative to where the load was applied will simply push out. This kinks the tube and makes it easier to bend. If there were an internal gusset to hold a tube 'together' normal to where the load is applied, essentially connecting the basses of the two 'arcs' then the principal of load transfer which makes arcs strong would come into play and the strength of the tube would depend on the tensile strength of the gusset used to hold the sides of the tube together. Good luck trying to weld an internal gusset down the length of a tube tho.

dont mean too steal thread but what does DOM stand for

 

[4x4junkie]

Drawn Over Mandrel.

It's a cold-working process, increasing the molecular density of the steel (DOM tube is usually also of a slightly higher carbon steel than normal (HREW) tube, which also gives it more strength)

just for reference and update, ive had my truck out a few times and at least once each time drug on the bottom of the sliders and while it was not super hardcore with all the weight of the vehicle on one pin point, it was noticeable in the cab (like the feeling of no suspension). they have held up fine....just scraping off of the paint is all...no denting. course im a slow driver and dont ever bash things anyway. it is the vehicle i drive to school and work everyday so it has to work.....

Good to hear a "field report" for once. Also good to hear that they have held up so far.
