1.625" Chrome Moly is .083" wall is 1.367 # per foot The weigh savings comes from the fact that you are using a thinner wall material. However in this case the Chrome Moly cage will weigh 29.1% less than Mild Steel. Tom Last edited by PROSTOCKTOM; 08-30-2016 at 10:07 AM. |

Re: 66 chevy ll cage
I usually use the 33% figure as a rule of thumb, since most cars done in the last 20 years have .134"wall ERW tube instead of .120 DOM
Average chrome moly roll cage weighs around the same as a .134" wall mild steel roll bar. The added safety from a cage in a car like a shoebox Nova is worth the price and even a few pounds. It's not just how fast you are going any more, you have to consider the 150+mph bullet on 9" tires in the other lane .

Re: 66 chevy ll cage
Our Nova really benefited from a cage compared to when it had a moly bar in it. They are not the strongest cars. I believe there is a rule change in stock that might allow you to extend the bar past the firewall now. Worth checking it out.
