This braking system is equipped with a robust 4-piston S4 caliper, perfectly paired with a 13-inch, one-piece slotted and drilled rotor that’s zinc plated for added durability. The S4 caliper is designed with D.O.T compliant dust and weather seals, ensuring it stands up to the elements, and it utilizes the popular DR1 pad type for reliable performance.

You'll appreciate the billet aluminum hubs that come pre-assembled with top-notch bearings, all packed with Redline synthetic grease to keep everything running smoothly. Plus, the billet dust caps add an extra layer of protection. We’ve included all the necessary mounting brackets, stainless braided hoses, and hardware to make installation a breeze.

The 13-inch SS4 is compatible with most 17-inch wheels or larger, making it a versatile choice for your ride. It fits a variety of classic models, including the 1964-72 GM A-Body, 67-69 F-Body, and 64-74 X-Body cars with OE spindles. You’ll also find it fits DSE, Heidt's, Fatman, Ridetech, and L&H drop spindles, giving you plenty of options.
