• PowerStop full-cast design front rotors replace the factory 2-piece Brembo front rotors on the SRT - no caliper or bracket modifications required

• 5-lug bolt pattern (5x127mm / 5x5.0 in.)
• No special modifications required - direct bolt-on installation

Features

Product Description

The PowerStop K5957 Z23 Evolution Sport Front Brake Kit is a front brake upgrade for the 2012-2020 Jeep Grand Cherokee SRT8/SRT and the 2018-2020 Dodge Durango SRT - all models equipped with the factory Brembo 6-piston front caliper and OEM 2-piece front rotor. PowerStop's full-cast G3000 iron rotors replace the factory 2-piece floating front rotors with a proven one-piece design, eliminating the potential for the ring-and-hat separation issues that can occur on 2-piece rotors under sustained heavy use. The Z23 Carbon-Fiber Ceramic pads deliver improved stopping power and significantly less dust than factory pads.

This kit fits SRT/SRT8 front caliper models only - not standard Grand Cherokee or Durango models, and not 2021+ SRT or Trackhawk. For the matching rear Z23 kit, see PowerStop K5956. For the complete front and rear Z23 kit, see K5958. For the Z26 Street Warrior version of this front kit, see K5957-26.
