Out of stock

SKU: C6-A-4102 Categories: , , Tags: , ,


Our Chevrolet Corvette C6 Z06 SFI roll cage/ chassis comes CNC notched and bent for quick fitment and welding out of chromoly.

To make for an easier install, all of our tubing comes with laser-etched guides showing where the tubes should connect and also allow for prior drilling of the tubes for TIG welding relief, however please note: 4130 Chromoly can NOT be “laser etched” on the back side of bends.


  • meaning you will need to take extra steps to insure TIG relief holes are placed in the right spot as well as that tube’s placement. With all of the other etches present, you should still be able to place the tubes correctly with ease.

This kit includes all tubing shown in photos and 2 SETS OF BASEPLATES in order to attach to the aluminum chassis via dual sandwiched steel baseplates to properly attach the chromoly cage to the aluminum chassis at the inside of the frame rails on the bottom.
