• Does NOT fit Dodge Charger 2011+ in standard or non-SRT trims - those use a different rear brake specification
• Rear axle kit only - a separate front kit is required for a complete brake service; see K4695 (Z23) or K4695-26 (Z26) for the matching front kit

Product Description

The PowerStop K4583 is a rear Z23 Evolution Sport brake upgrade kit engineered for the performance-caliper platform used across the Chrysler 300 SRT8, Dodge Challenger SRT8 / SRT 392 / SRT Hellcat / Scat Pack, Dodge Charger SRT8, and Dodge Magnum SRT8. These models share a common 350mm rear rotor specification, and the K4583 delivers matched Z23 carbon-fiber ceramic pads and cross-drilled, slotted rotors purpose-built for that platform - providing improved stopping power, reduced brake dust, and superior heat management over OE replacements.

Buyers must verify rear rotor diameter before ordering. This kit fits the 350mm rear rotor specification only - standard Chrysler 300, Challenger, and Charger models use a smaller 320mm rear rotor and require a different kit (K1719). This kit covers the rear axle only; the matching front kit (K4695) is available separately. Backed by a 3 Year / 36,000 Mile warranty and a 60-day hassle-free exchange, the K4583 is a proven rear brake upgrade for owners of America's highest-output LX/LC platform vehicles.
