Collapsible Steering Assy Long

The Collapsible Steering Assy Long from Allstar Performance is a purpose-built steering shaft engineered for race cars and high-performance vehicles where driver safety and space efficiency are paramount. Designed to absorb impact energy during frontal collisions, this collapsible steering assembly reduces the risk of steering column intrusion into the cockpit—a critical safety feature mandated in many racing sanctioning bodies. Measuring 24½ inches long with a 7-inch collapse zone, this universal component fits a wide range of steering configurations and is ideal for fabricators, race teams, and enthusiasts building or upgrading custom vehicles.

The assembly features a ¾-20 spline connection, a standard in racing applications, and is constructed from durable steel with a protective black paint finish to resist corrosion and wear. The collapsible design works by allowing the steering shaft to compress axially under load, dissipating impact energy that would otherwise transmit directly to the driver—this is distinct from rigid shafts and represents modern safety engineering in motorsports. Weighing just over 3 pounds and spanning 19.9 inches in its packaged dimension, the unit is compact enough for tight engine bays while maintaining the full 24½-inch functional length required for proper steering geometry and reach.

This collapsible steering assembly is most beneficial for vintage hot rod builders, circle-track racers, and street rod fabricators who need to meet safety regulations or upgrade older vehicles with modern crash-protection technology. The universal spline design accommodates most aftermarket steering boxes and rack-and-pinion conversions, making it suitable for DIY restoration projects and professional shop installations alike. Proper installation requires alignment with your vehicle's steering geometry and confirmation that your steering box or rack input shaft matches the ¾-20 spline standard—consult your vehicle's build manual or contact a steering specialist if adapters are needed.
