[QUOTE="stuftmunky2k, post: 611760, member: 9716"] Commonly available DOM tubing is usually 1020 or 1026 so you dont need to be specific on the type of DOM. In the normalized condition 4130 tubing comes in, it is not much sronger than DOM, you would probably never tell the difference if you built two identical chassis, one 4130, and one DOM and did some sort of testing. DOM will work just fine, The drawback to using DOM is that you won't be able to tell people that "my buggy is built out of chrome moly", its kind of like saying "ooh my axles are made out of 300M" when a properly designed 4340 or 4140 axle would work just fine and the is other drawback is that chrome moly is lighter and stiffer than DOM Quoted from mr goat built himself. I do a decent bit of a chassis work at the race shop out of chromoly and he sends everthing out to get heat treated after welding. There is also the fact the person welding it has to be up to snuff on his heat input. Last thing you want is to have a weld joint fail from to much heat input. [/QUOTE]
