Product description

This 70mm rear flange is a precision-engineered mounting component for the main shaft assembly of Snap-On wheel balancers. It serves as the primary mating surface between the balancer's motor/shaft and the wheel mounting hardware, ensuring that the assembly rotates with absolute concentricity. Even minor deformation, cracking, or surface wear on this flange can introduce runout into the balancing shaft, leading to inaccurate readings and "ghost" vibrations that are impossible to balance out. Because the accuracy of a wheel balancer depends entirely on the stability of its rotational axis, maintaining a perfect flange is essential. Replacing a compromised rear flange restores the factory precision of your machine and ensures reliable balancing results for every customer.

Product highlights

• Precision-machined 70mm diameter provides a perfectly flat and true mounting surface.
• High-grade alloy construction resists warping and structural fatigue over time.
• Critical for balancing accuracy by maintaining perfect shaft-to-hub alignment.
• Direct replacement for the original rear flange on high-performance balancers.
