Thread: frame advice

Tweet

You should check on how to get your vehicle titled and registered in Arizona before you get too far along. Unfortunately, AZ has not implemented the SEMA model.


(Bear in mind that rules / laws in other states will likely be posted here, but other states have absolutely no bearing on AZ.)

stock frames were 4 inches






also check out the drawing for the A body on a 32 frame---6 inches and also has kick up over rear axle------------

Ryan 3/16" is way overkill, 1/8" is just fine

1/8" sounds too thin too me with big Z's and a 460. Maybe a drag car but on a street cruiser I can't imagine that 1/8" tubing will like the flex and bouncing over time. Just my opinion though.

Its definitly not mate, I can't think of any chassis manufacturer that uses 3/16" because as Jerry said earlier 1/8" will take any engine combination you can throw at it.

Check out the standard passenger car frame, the majority of them are stamped from 10ga. steel, then are only a "C" channel which by design has much less strength then either rectangular or round tubing....
