About This Product
Arlen Ness Rotator II 11.8 floating brake rotor. Right-side fitment. The stainless steel friction ring floats off the precision-machined inner carrier. It expands as it heats. A fixed rotor would warp. This one does not. Heat dissipates through the ring. The lever feel stays consistent. The 11.8 inch diameter gives you the leverage. Sold individually.
Manufacturer part number: 300-053.
