66-67 Chevy II Main Hoop

The 66-67 Chevy II Main Hoop from Competition Engineering is a purpose-built roll cage component designed for serious street and strip enthusiasts who demand structural rigidity and safety in their classic muscle car builds. Built for the first-generation Chevrolet II platform, this main hoop serves as the backbone of a complete roll cage system, protecting occupants during high-stress driving conditions while maintaining the vehicle's classic proportions. Whether you're building a dedicated track car, street racer, or show-quality restomod, this component is essential for meeting safety standards and providing peace of mind at the strip or road course.

Constructed from high-strength steel tubing, the 66-67 Chevy II Main Hoop is engineered to absorb and distribute impact energy across the frame without compromising interior space or visibility. The hoop's geometry is specifically contoured to fit the Chevy II's compact dimensions while providing maximum structural support where it matters most—directly behind the driver and passenger compartment. Weighing 28.25 lbs, this component integrates seamlessly with Competition Engineering's complete cage systems, offering professional-grade welding points and precise fitment that eliminates the guesswork from cage installation and ensures uniform load distribution during extreme driving events.

Fabricators, drag racers, and street performance builders will appreciate the precision engineering that allows this main hoop to integrate with floor pans and crossmembers without requiring extensive modification. Installation is straightforward when combined with Competition Engineering's tube connectors and gusset kits, making it an ideal foundation for both DIY welders and professional shops. The 40.5 x 50.5-inch dimensions ensure proper clearance for shoulder belts and seats while maintaining the structural integrity required by sanctioning bodies at NHRA events and other racing venues. This main hoop is fully compatible with the 1966–1967 Chevrolet II chassis and pairs perfectly with Competition Engineering's matching components for a bolt-together or weld-in complete safety system.
