    Performance Machine Four-Piston Differential-Bore Rear Caliper For Harley Stoppers on stock Harley products are rarely outstanding, sometimes adequate, and often awful! Performance Machine has been cranking out high-quality juice brake products for as long as anyone in the custom Harley game. A great set of grabbers can transform your bike - and transform the way you ride your bike. Differential-bore calipers are special because they have differently sized pistons that engage the rotor at slightly different speeds, giving them a very progressive feel, and ensuring that more powerful braking comes with periods of longer and harder lever travel. With looks as sleek and show-stopping as their performance, PM calipers represent one of the most effective ways to get looks and performance from your machine per dollar spent. Features : Dual-disc applications require a left and right caliper Use either OEM-style or Performance Machine rotors Available in Chrome, Contrast Cut and Black Ops finishes Include brake pads, bleeder screw and banjo bolt Made in the USA
