Chevrolet SS Brake Rotor (1) - Rear - DBA - 4000 Series HD - `15-`17 is a direct-fit rear replacement rotor engineered for drivers seeking durable, consistent braking performance. This single rear rotor provides the OE-style smooth finish of DBA’s 4000 Series HD while offering the metallurgy and cooling advantages of their competition-proven design.

Cast from XG-150 high carbon alloyed iron and processed with DBA’s Thermal Stability Profiling (TSP), this rotor resists heat-related fade and maintains structural integrity under repeated heavy use. The patented Kangaroo Paw ventilation uses 144 diamond- and teardrop-patterned pillars to increase surface area and improve cooling compared with traditional straight-vane designs — helping to reduce temperatures and preserve pad life. The 4000 Series HD keeps a plain, OEM-style face for a factory look, making it suitable for street-driven performance cars and controlled race divisions that require a subdued appearance. Each rotor is marked with THGP thermo-graphic paint for quality verification and shipped in moisture-proof corrosion protection packaging.
