New Tri-Spool Design Enhances Performance and Longevity

Amick Rigging and Racing, in collaboration with USAC, has introduced a significant update to the Sprint Car King Pin Tether Restraint system: the Tri-Spool Termination Fitting.

This precision-engineered, three-piece titanium fitting—dubbed the Tri-Spool—allows the tether to pivot at the king pin termination point. The result? Reduced binding and improved flexibility just below the king pin, extending the life of the tether and improving overall performance.

The Tri-Spool is compatible with most spindles used in World of Outlaws (WoO) and USAC series racing, especially in setups where rotor clearance is a concern.
