High-strength, cast steel frame, pin and handle. Upper Pin Guard and an internally mounted spring helps protect from damage. The 2.125? (54mm) diameter steel pin minimizes towbar slop. Pin wear is decreased due to its larger surface area and heat-treating to increase hardness. Throat area features a negative slope to minimize towbar chucking (bouncing). Corrosion resistant coatings on all components.
