Swing Out Door Bar Kit 1-5/8in Tube

The Swing Out Door Bar Kit 1-5/8in Tube from Competition Engineering is a weld-on reinforcement system engineered for serious street and strip machines that demand chassis rigidity and safety compliance. This kit addresses a critical weak point in many vehicles—door frame flex during acceleration, cornering, and impact—by triangulating the door structure with high-strength steel tubing. Purpose-built for both bracket racing and high-horsepower street applications, this swing-out design allows door access while maintaining structural integrity, making it ideal for drivers who won't compromise on safety or practicality.

Constructed from 1.625-inch diameter steel tubing and NHRA-certified for competition use, the Swing Out Door Bar Kit transfers door panel stress directly into the vehicle frame through a welded installation. The larger 1-5/8in tubing diameter provides superior bending strength and torsional resistance compared to thinner alternatives, while the universal fit design accommodates most domestic and import platforms. Competition Engineering's engineering focuses on minimizing weight penalty—just 1.6 lbs—while maximizing structural support, and the natural steel finish allows custom powdercoating or protective coating to match your build aesthetic and prevent corrosion.

Mechanics and fabricators installing this kit should plan for full-frame welding; this is not a bolt-on accessory and requires proper TIG or MIG equipment and welding certification to ensure safety and structural integrity. The swing-out configuration is especially valuable for door-heavy vehicles or those with modified interiors where interior door bar placement may interfere with seating or roll cage geometry. Competitors running NHRA-sanctioned events will appreciate the certification stamp, while street enthusiasts benefit from the real-world chassis stiffness improvement that translates to sharper handling and reduced body roll during aggressive driving.
