Paragon 2-Piece Front Rotors for Jeep Grand Cherokee SRT and Dodge Durango SRT
Paragon Performance 2-piece front rotors for Jeep Grand Cherokee SRT and Dodge Durango SRT applications. Designed for track and race use, these floating rotor assemblies deliver strong braking performance, improved cooling efficiency and reduced unsprung mass without modifications to the factory brake system.
Directional ventilation vanes create suction and turbulence to guide cool air through the rotor, improving heat dissipation and increasing resistance to cracking under harsh track conditions. The directional design runs up to 30% cooler than OE rotors and can increase cooling efficiency by up to 30%, helping minimise brake fade and judder during extended sessions.
Each rotor ring is made from CM-250 special-formulated high-carbon alloy cast iron for strong bite, thermal stability, high-temperature strength and durability. The rings are heat-treated to release stress and reduce deformation and vibration, then finished with CBN surface machining for consistent bedding with new brake pads. Lateral run-out is kept within 0.03 mm and balance variation within 2 grams.
The fully floating 2-piece design allows controlled thermal expansion while minimising deformation and helping the rotor self-centre with the pads. The slotted face pattern maintains a clean pad contact surface, dissipates heat and gases, and helps prevent water films from forming between the pad and rotor in wet conditions.
CNC-machined from lightweight 6061-T6 aerospace-grade aluminium, the hats are engineered for high strength and durability under extreme track conditions, then Mil-spec Type III black hardcoat/hard anodised for improved wear and corrosion resistance. Material is removed where possible to save weight while maintaining structural integrity. The assemblies are direct bolt-on replacements designed to work with the OEM ABS and brake system while maintaining factory brake bias. They are compatible with OEM brake pads or aftermarket pads with the same pad depth (D).

Available part numbers:
- Black hard anodised hat: P2R.239.380.340.21900.05.01.01.F
- Clear hard anodised hat: P2R.239.380.340.21900.05.01.02.F
Hard anodised clear hats are recommended for track and race applications because they will not discolour under extreme heat. Black hardcoat anodised dyed hats may discolour above 500°F / 260°C.
