Paragon Performance friction rings for Jeep Grand Cherokee 6.4 SRT (front axle)

These friction rings are a direct replacement for 2-piece Paragon Performance brake discs and also for the original brake discs of the Jeep Grand Cherokee SRT with performance brake.

Paragon Performance friction rings provide superior braking and cooling efficiency optimized for track use. The directional ventilation slats feature achieves suction and turbulence, directing cool air through the brake disc to improve heat dissipation and increase resistance to cracking in harsh track conditions.

The friction rings are made of CM-250, a special high carbon casting alloy that ensures optimal bite, thermal properties, high temperature strength and durability.
The brake disc rings are heat treated to reduce stress in the brake disc and thus prevent deformation and vibration.
They are then machined using a state-of-the-art CBN surface treatment to ensure better break-in with new brake pads.

Vibrations are reduced as brake disc side runout is kept within 0.03 mm and balancing is within 2 grams.
All friction rings have undergone strict quality controls and testing to ensure that the brake discs are suitable for their purposes.
The two-piece design allows thermal expansion of the brake disc while minimizing deformation and ensuring centering of the brake disc to the brake pads.
A slotted brake disc improves brake stability by maintaining a clean contact surface and dissipating the heat and gases generated when the brake pads come into contact with the brake disc.
Slotted brake discs have a decisive advantage over bare brake discs in wet or rainy conditions, as they prevent the formation of water films between the brake pad and the brake disc.

Due to the high vehicle weight and the lack of effective brake cooling, premature cracks on the standard brake discs after use on the racetrack or under heavy use are not uncommon.
Paragon Performance brake discs can be an effective solution to this problem while improving pedal feel and brake modulation.
