Centric 120.44157CRY CryoStop Premium Cryo-Treated Disc Brake Rotor Rear

The Centric 120.44157CRY is a Premium CryoStop rear disc brake rotor engineered as a direct OE replacement with enhanced durability through cryogenic treatment. Sold and supported under the StopTech brand — Centric's high-performance and racing division — this rotor is built for drivers who demand reliable, long-lasting braking performance.

Cryogenic Treatment Process:

The CryoStop process is a one-time stress relief treatment that subjects the rotor to both cold and heat cycling using a proprietary, computer-controlled 24-hour process. The rotor is gradually cooled to -300°F, then raised to over +300°F, and finally returned to room temperature. This deep cryogenic treatment permanently refines the molecular structure of the cast iron, improving wear resistance and extending service life — particularly beneficial in fleet, emergency vehicle, and high-demand driving applications.

Key Features:

• Cryogenic Treatment — Reduces residual stress and improves rotor durability and service life
• Black E-Coat Finish — Electrostatically applied anti-corrosive coating engineered to withstand 400+ hours of salt water exposure, far superior to competitor spray paint finishes
• Double Disc Ground Friction Surface — Eliminates lateral runout and ensures a consistent friction surface for optimal braking performance and effective pad break-in
• Symmetric Vane Split-Core Castings — Promotes uniform heat distribution across the rotor face for consistent braking under load
• 100% Fully Machined Finishes — Provides better rotor balance and a cleaner, more finished appearance
• Direct OE Replacement — Blank, 1-piece design matches factory specifications and installation requirements
• QS and ISO Quality System Standards — Manufactured to meet rigorous quality system certifications

The Centric 120.44157CRY CryoStop rotor delivers premium-grade corrosion protection, dimensional accuracy, and extended service life in a direct-fit replacement package — an ideal upgrade over standard OEM rotors for drivers prioritizing longevity and consistent stopping power.
