Our Chevrolet Corvette C6 NHRA 8.5 Cert roll cage that is convertible to 25.1/25.2 SFI Chassis CageKit is designed to be upgradable to a 25.1/25.2 tubular chassis by simply removing the floor to install the subfloor structure then trim the floor to fit, secondly you will need to unbolt the roof to access the “hard to reach” welds of the additional tubes needed to be added. This will take significantly less than removing the entire cage to build a 25.1/25.2 chassis/cage.

This roll cage comes CNC notched and bent for quick fitment and welding out of 4130 1.625″ .083 wall 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.

“Steel Chassis Only”

  • This kit retains the factory headliner

This kit MUST be TIG welded only as per NHRA & SFI regulations.

This kits primary structure uses 1.625” x .083” 4130 Chromoly tubing to meet NHRA 8.5 Cert requirements. In other words, you should have no problem passing tech if you installed the kit correctly. It’s important to note that this is a weld in kit and it requires a certain amount of skill and patience to make it fit right. The more time you take fitting and measuring, the better the overall cage will fit.

See NHRA Rulebook “Section 21 page 26″ for general guidelines of 8.5 Cert 

ALL SALES ARE FINAL because our roll cages/chassis are made to order and will ship once completed.
