IMO, leave the 4130 for suspension and dragster chassis'. If you can't stick it in an oven, make it out of mild. ;)[/quote]

sorry but i strongly disagree with this, 4130 is the best for cages hands down! I come fron both the NASCAR world and the insane world of desert racing, where 4130 can save your life compared to DOM. We had both an 4130 nascar chassis and a DOM chassis, and besides the 4130 being stronger it was also lighter up top because of the .095 wall verses the .120 wall DOM. IMO the 4130 chassis also handled better because is gave less flex overall.

You can MIG 4130 and it will be fine. TIg is the preference but not everyone can do this.

Trophy Trucks and Class 1's are all 4130 and some MIG welded with 95% TIG welded, none of them are heat treated and they withstand the most insane forces on earth, there is no computer that can simulate the forces that a 4130 off-road chassis sees. 140+ MPH through the desert is intense and 4130 is the only way to go.

But i know that this is kinda like apples and oranges, i still prefer 1.75" .095 wall 4130 for musclecar cage work. You use mild filler rod for the cage work because it is not going to be heat treated.
