I know DOM .120" is stronger, but I heard that HREW 1.75" x 0.120" is cheaper and still strong. I can get some pretty good prices on the tube because we have a machine shop for "school related projects" lol . I don't do crazy rock crawling or anything, but there are always chances for back flops. I'm wondering what material most guys are running for their cages and if I should just cough up the extra $$$ for DOM for the cage. RTI fabrication is going to do the work, and Josh (the owner) does some incredibly clean work. So it won't be some hack job with no planning. Will a well-designed cage from made from HREW be tough enough?

well designed HREW will be plenty strong.
if you forsee beating on the cage a lot, DOM will take punishment a lot better.

my cage is made from 1 3/4" HREW 120 wall.
It will work fine.
here is the link to it.

i work with tubing all day,yes DOM is nice if you have the money,but it is not needed regardless of what everyone says.
if you were building a comp buggy then i would say yes,as many rule books state either DOM or ChroMo.

Agreed. A friend of mine has built circle track dirt cars for years, he uses nothing but .095 HREW. He's taken some serious high speed wall hits with minimal damage and no injuries. He's also built 2 comp buggies with the same tubing and has taken many forward rolls, backward rolls, and just generally beat the snot out of them with minimal damage. Around here price is a huge determining factor, .120 wall 1.75"OD DOM=$7.20/ft versus .120 wall 1.75"OD HREW=$1.25/ft

either one, well designed, will be just fine. You will find that 1 1/2 will work better for you if you are making an A pillar to go between the dash and door.

Thanks guys. I'm not really familiar with either one, and I was thinking it would probably take about 50'- 55' of tubing for the cage. It's going to be pretty basic, along the lines of this very familiar zuk except with the spreader above the dash instead of below.

my cage is built out of 1 3/4 .120 wall hrew, it has taken some verry hard hits. my daily driver zuk has a 1.5 .095 hrew cage which I think I like better. stick with hrew, you will be just fine.

How does $2.00 a foot sound for pricing? They price by the pound and that was what I came up with.

2$ seems about right since the price of steel is going higher all the time. My cage and upper frame is 1 3/4 HREW and it also has taken some hrad hits and held togehter fine. MIG weld it or if you want to take more time TIG weld it and it should do great for you. The JR2 bender is a great tool and there are other copies of it out there.

Bump.... I just wanted to tell you guys that I ended up getting 60' of 1 3/4" HREW 120 wall for $1.56/ft, which seemed like a fair price to me.

sounds fair to me
