if you go chromoly you can do .o95 and it is lighter and safer than dom, .120 chromoly is for trophy trucks and class 1 buggies.
It's just that i have 60 feet from my Bronco, that I haven't used and I was thinking about it. I think the 1 3/4 .120 wall is for PreRunners, 2in is for the big boys.

.120 4130 is overkill. Chromo is not lighter than DOM. It is just stronger which means if you wanted to you could use a thinner wall chromo than you would DOM. Then you would save weight. A properly designed DOM cage is more than enough for a Rhino. BITD rules say you must use at least .095 DOM

Way overkill...My 3000# mustang racecar cage is made of .095 chromoly. .120 wall is way over kill. .095 would be overkill. Some people run even thinner wall when running chromoly in this app, but I think better safe then sorry. .095 should be good. Whats more important is how it's built. I'm sure a pro could build a stronger cage from PVC then some of the homebuilt deathtrap cages i've seen out there.

Did you guys know that NASCAR specifies DOM?
Its because you can get better and safer welds with DOM.
Yes they do, because of the flexing of DOM, it will bend more before it breaks. It has nothing to do with safer welds.


Gabe, I would do .095 chromoly main hoops and .083 cross bracing. Dustin (AZBDBY) has good designs if you want to make your own. I am sure he would send you some info. :good:
