Performance Friction Medium-Duty Retrofit Rotor Part No. 390.086.20
Available from Performance Friction
Performance Friction medium-duty retrofit rotor with isolated ABS ring (patent pending). Performance Friction's new medium-duty retrofit rotor features a patent pending solution to the known problem of ABS signal loss commonly found on medium truck applications.
Faultless ABS operation
-Precision machined alloy ring for improved signal strength
-Isolated tone ring for reduced heat transfer
-Protective plating to prevent corosion
With older technology rotors, the ABS ring is cast into the rotor, resulting in inconsistent tooth sizing and spacing. The problem is worsened by the fact that as iron increases in temperature, magnetism decreases corrosion is accelerated, which may result in ABS signal faults. In third party GM9540P corrosion testing with high temperature heat soaks, the Performance Friction retrofit rotor with isolated ABS ring lasted more than five times longer than other rotors.
