Default is my tube strong enough

i am building some radius arms for my 1985 k10 chevy and i was donated some 1-7/8"dia 3/16wall DOM tubing the tubes will only be about 27" long with no bends in them and the truck should weigh about 4500 pounds. should i still brace them or will they be ok?

that size sounds fine. are you gonna jump the truck? either way roll cages are made out of that size material and hold up pretty good.

Roll cages are a whole different animal with different requirements. 3/16 is WAY too small for links on a lightweight buggy, much less an 85 K10!!

*Personally* I wouldn't consider anything less than 3/8ths for lowers... (and I wouldn't even go that thin)

Depends on the wheeling and on the weight of the truck. My old CJ had 1.75 x .180 DOM links way back then and never bent them...Did the Badlands , Paragon, trail riding, wheel stands (yes wheel stands).

Yeah, but that was before the age of enlightenment. These days everyone nees to go overkill because they read some guy on pirate bent his links...


I wouldn't see any issue at all with that size, EXCEPT if your wheeling has you crashing the links down onto rocks/logs/etc.

That isn't too long of a link length, I think it'd be fine. For example, its not uncommon for people to have long lowers around 40-45" long. A 27" long 1.875x0.188" link is stronger, in bending moment, than a 44" long 2.00x0.313" link. (though not as dent resistant).

What other kind of wheeling is there...?





But do whatever link size floats your boat. I've seen too many friends waste money on thin links before finally going big to ever make that same mistake myself

Ah fukc it. They're only radius arms and it's prolly only going in sand and mud. Just run what ya got and fix later if it's a problem.

If it's for the truck in your Avitar go for it.By the looks of things you don't put that in the rocks and if you do you wheel for minimal body damage.
