Paragon Performance Friction Rings for Jeep Grand Cherokee 6.4 SRT (Front Axle)

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

Paragon Performance rotor rings offer superior braking and cooling efficiency optimised for track use. The directional ventilation fin feature achieves suction and turbulence, directing cool air through the brake disc to improve heat dissipation and increase resistance to cracking under tough track conditions.

The rotor rings are made of CM-250, a special high carbon cast alloy that ensures optimum bite, thermal properties, high temperature strength and durability.
The rotor rings are heat-treated to relieve stresses in the brake disc and thus prevent deformation and vibration.
They are then turned with a state-of-the-art CBN surface treatment to ensure better running-in with new brake pads.

Vibrations are reduced as the lateral runout of the brake disc is kept within 0.03 mm and the balancing is within 2 grams.
All rotor rings have undergone rigorous quality control and testing to ensure that the brake discs are fit for purpose.
The two-piece design allows thermal expansion of the brake disc while minimising deformation and ensuring centring of the brake disc to the brake pads.
A slotted brake disc improves braking 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 weight of the vehicle and the lack of effective brake cooling, premature cracks on the standard brake discs are not uncommon after use on the race track or under heavy use.
Paragon Performance brake discs can be an effective solution to this problem, while also improving pedal feel and brake control.
