Dynamic Friction 830-42023R Disc Brake Rotor - Rear Right

Overview

The Dynamic Friction 830-42023R is a drilled and slotted disc brake rotor built for specific Jeep rear brake applications. It combines a directional surface with a rust-resistant coating and Geospec Silver Grey hat finish for a clean, service-ready appearance.

Compatible with Jeep Grand Cherokee and Jeep Grand Wagoneer rear right applications, this rotor is sized for the listed bolt pattern and hub dimensions. The 830-42023R is part of DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on performance-oriented rotor surface design and corrosion protection.

• Slotted X drilled surface for consistent brake contact and heat management
• Rust resistant coating for added protection against corrosion
• Directional brake surface for application-specific fitment
• Plain disc finish with Geospec Silver Grey hat finish
• Solid rotor construction with 5-lug mounting pattern

Detailed Description

This Dynamic Friction brake rotor is engineered around the listed dimensions, including a 285 mm outside diameter, 60.5 mm overall height, 72 mm center hole diameter, and 114.3 mm bolt circle diameter. The solid rotor design and directional slotted-and-drilled surface support stable braking characteristics for the specified Jeep Grand Cherokee and Jeep Grand Wagoneer rear right fitments. Part number 830-42023R is a direct match for the applications shown in the fitment data.

Common Uses

• Replacing a worn or below-spec rear brake rotor
• Addressing brake pulsation caused by rotor wear or surface irregularity
• Restoring braking performance when the rotor surface is scored or heat-affected
• Correcting corrosion-related rotor condition on the hub and braking surface

Installation Notes

Verify the vehicle’s rear right fitment, chassis break point, and disc brake configuration before installation. Confirm the rotor dimensions, bolt pattern, and center bore against the existing part to ensure proper fit. For 1993 Jeep Grand Wagoneer, the application is for vehicles with rear disc brakes; for 1993-1994 Jeep Grand Cherokee, the fitment is limited to chassis number 358-321 and earlier.

Quality Assurance

Dynamic Friction’s DFC Geoperformance Rotor line is positioned as a performance-focused rotor family with corrosion-resistant finishing and application-specific engineering. Part number 830-42023R is built to the listed specifications for the confirmed Jeep applications.
