This system boasts a robust 4-piston S4 caliper that's perfectly paired with a 13-inch, two-piece slotted and drilled, zinc-plated rotor. The S4 caliper is designed with D.O.T compliant dust and weather seals, ensuring durability and reliability, and it utilizes the popular DR1-C pad type for optimal performance. The rotors come pre-assembled with high-grade NAS stainless hardware, making installation a breeze.

What sets Baer's design apart is its unique backing plate, which not only serves as a caliper mount but also integrates a modern one-piece park brake shoe assembly. You'll also find stainless braided hoses and hardware included in the package for added convenience.

The 13" SS4+ is compatible with most wheels that are 17 inches or larger, making it a versatile choice for your vehicle. It fits rear ends with GM Small Pattern 10/12 bolt bearings on the axle (BOA) with flush mount bearing housing ends (5x4.75", 5x5" BC).
