Dynamic Friction 830-42045R Disc Brake Rotor - Rear Right

Overview

Dynamic Friction 830-42045R is a drilled and slotted disc brake rotor built for rear right fitment on select Jeep Grand Cherokee and Jeep Grand Cherokee L applications. It combines a directional braking surface with a rust-resistant coating and Geospec Silver Grey hat finish for a clean, service-ready appearance.

Key Features

• Slotted X drilled surface for consistent pad contact and heat management.
• Directional brake surface for controlled airflow across the rotor face.
• Rust-resistant coating helps protect exposed surfaces.
• Geospec Silver Grey hat finish adds a finished OE-style look.
• 5-lug pattern with 127 mm bolt circle and 72 mm center hole.

Detailed Description

This Dynamic Friction brake rotor is engineered around the dimensions and surface design needed for rear right service on compatible Jeep platforms. The 350 mm outside diameter, 41.5 mm height, and 22 mm nominal thickness provide the physical specifications required for the listed applications, while the 20 mm discard thickness gives a clear wear reference during inspection. The slotted and drilled face is intended to support more even pad interaction and stable braking performance under repeated use. Part number 830-42045R is the reference to use when matching this rotor for Jeep Grand Cherokee and Jeep Grand Cherokee L fitment.

DFC Geoperformance Rotor - Drilled and Slotted is the product line designation for this rotor family. It identifies a performance-oriented rotor design with drilled and slotted surface geometry and corrosion protection features, making it a fit-focused option for buyers looking for a direct replacement style brake rotor with a more aggressive surface treatment. Part number 830-42045R should be verified against the vehicle’s rear right brake specification before ordering.

Common Uses

• Brake pulsation caused by uneven rotor wear.
• Reduced braking consistency from heat buildup.
• Surface corrosion on the rotor hat or braking face.
• Noise or vibration associated with worn rear brake rotors.
• Replacement needs for rear right brake service on Jeep Grand Cherokee and Grand Cherokee L models.

Installation Notes

Confirm rotor dimensions, bolt pattern, and rear right application before installation. Clean the hub mounting surface and inspect pads, caliper condition, and hardware wear during service. Because this rotor uses a directional braking surface, install it in the correct orientation for the specified side and application. Match part number 830-42045R to the vehicle’s brake specification to avoid fitment errors.

Quality Assurance

Dynamic Friction supplies brake components with application-specific sizing and finish details for accurate replacement selection. The rust-resistant coating and finished hat surface add protection and appearance benefits that support long-term serviceability.
