Mini Sprint Torsion Bar Bushing

The Mini Sprint Torsion Bar Bushing (ALL 55160) is a precision suspension component engineered to maintain proper articulation and damping in sprint car and lightweight race vehicle chassis. As a seasoned mechanic, you know that torsion bar systems depend on responsive bushings to transmit suspension geometry accurately and minimize parasitic friction during aggressive cornering. This 7/8-inch inner diameter nylon bushing isolates the torsion bar from its mounting points while allowing controlled flex, making it essential for drivers who demand repeatable handling and consistent lap times.

Manufactured from high-grade black nylon, this bushing resists compression set and maintains dimensional stability under the cyclic loads common in sprint racing. The 7/8-inch ID design fits standard torsion bar diameters used in Mini Sprint platforms, while the compact 4 x 1.55 x 7.05-inch footprint ensures straightforward installation without chassis modification. Nylon composition offers superior wear characteristics compared to rubber alternatives, extending service intervals and reducing warranty claims—a proven advantage for race teams running back-to-back events. The bushing's low weight (0.06 lbs) contributes minimal unsprung mass, preserving the precise weight distribution critical to sprint car performance.

Mini Sprint racers, fabricators, and suspension shops rely on this bushing for both new builds and mid-season replacement on worn torsion bar assemblies. Installation requires only basic hand tools and takes minutes per corner, making it an economical maintenance item that pays dividends in chassis consistency. Whether you're tuning a competitive entry-level platform or maintaining a fleet of rental race cars, the Mini Sprint Torsion Bar Bushing delivers the durability and precision fit that modern sprint racing demands.
