A complete balancing solution for large wheels up to Medium Duty Truck size. Fits all balancers with 40mm shafts. Proudly American-made from precision-machined, high-quality steel and aluminum. The oversized cone handles rims with extra-large center holes, while the offset backing spacer fills deep rims to ensure a solid, secure mount on the balancer. When choosing a cone, match it to your wheel's center bore diameter. For example, if your wheel's center hole measures 3" across, confirm that 3" falls within the selected cone's range before purchasing. IMPORTANT: Many wheel balancer models — even within the same product line — can have different shaft sizes. Always verify your balancer's shaft diameter before ordering to ensure compatibility and avoid returns. ---Steel Cone Range: 5.875" - 7.
