Birdcage Bolts

Birdcage bolts are specialized fasteners used in the rear suspension of sprint cars and other racing vehicles. They play a critical role in the torsion bar suspension system by securing the birdcage, a component that connects the axle tube to the torsion bars. These bolts are essential for the proper functioning of the entire sprint car chassis and racing suspension components.

When performing a rear end gear install or other maintenance, it's crucial to use the correct birdcage rear suspension bolts to ensure the integrity of the system. These torsion arm bolt and other motorsport fasteners are designed to withstand the high stresses and forces of competitive racing, providing the necessary strength and reliability for the vehicle's suspension.
