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 boasts a zinc plating for added durability. The S4 caliper comes with D.O.T compliant dust and weather seals, ensuring reliable performance, and it utilizes the widely favored DR1 pad type for consistent stopping power.

You'll find that the billet aluminum hubs are pre-assembled with top-notch bearings, all generously packed with Redline synthetic grease, and topped off with billet dust caps for extra protection. We’ve also included all the necessary mounting brackets, stainless braided hoses, and hardware, making installation a breeze.

The 13-inch SS4 is designed to fit most wheels that are 17 inches or larger, making it a versatile choice for your vehicle. It’s compatible with 1964-72 GM A-Body, 67-69 F-Body, and 64-74 X-Body cars using OE spindles. Plus, it works seamlessly with DSE, Heidt's, Fatman, Ridetech, and L&H drop spindles.
