This system showcases a robust 4-piston S4 caliper paired with a 13" two-piece slot, drilled, zinc-plated rotor. The S4 caliper comes equipped with D.O.T compliant dust and weather seals, and it utilizes the widely-loved DR1-C pad type. You'll find that the rotors are pre-assembled with high-grade NAS stainless hardware for added durability.

What sets Baer's design apart is its unique backing plate, which not only serves as a caliper mount but also cleverly houses a modern one-piece park brake shoe assembly. Plus, we've included stainless braided hoses and hardware to ensure everything runs smoothly.

The 13" SS4+ is designed to fit most 17" wheels and larger, making it a versatile choice for your setup. It's compatible with rear ends featuring GM small pattern 10/12 bolt bearings on the axle (BOA) with non-flush mount housing ends (5x4.75", 5x5" BC).
