so i've decided to make a set of rock sliders with my buddy ... I plan to use 1.5 " diamter tubeing ... Should i use .120 wall ? i know thats really strong and what most roll cages are made out of but i probably don't need it quite that strong ... i'm concerned about weight .. any ideas ?

what wall diameter for like a baja bumper front or rear with no hitch ?

what diamter for front and rear bumpers with a hitch ? i assume 1/8 with a hitch cuz thats what james duff uses but 2" diamter.

 

If it's just for looks, .063" is easy to work with but not very strong. I would use something like 0.120" wall for anything that is likely to take a hit.

 

Since all the stuff i have planned for the future is basicaly for body protection and nothing to do with looks i guess i better stick with the .120

thanks bob !

 

depends on material.

 

Steel motorcycle racing frames are often done in 0.049" or 0.063" tubing because these have an excellent strength-to-weight ratio and are easily formed, even in chromoly. One problem is that they dent fairly easily though. Not good for bumpers or sliders, IMO.

 

industry standard is .120 or .188

much thicker then that and you need a NICE bender to bend it.
