Dynamic Friction 830-42045L Disc Brake Rotor - Rear Left

Overview

The Dynamic Friction 830-42045L is a Geoperformance drilled and slotted disc brake rotor built for specific rear-left applications. It combines a directional braking surface with a rust-resistant coating and Geospec silver gray hat finish for a clean, service-focused design.

Key Features

• Drilled and slotted rotor surface for consistent brake pad contact and heat management.
• Directional braking surface for controlled airflow and surface cleaning.
• Rust-resistant coating helps protect exposed surfaces from corrosion.
• Geospec silver gray hat finish adds a finished appearance and added surface protection.
• 5-lug pattern with 127 mm bolt circle and 72 mm center hole diameter.

Detailed Description

This Dynamic Friction brake rotor is engineered for Jeep Grand Cherokee and Jeep Grand Cherokee L rear-left fitments. The 350 mm outside diameter, 22 mm nominal thickness, and 20 mm discard thickness provide the dimensional profile needed for the listed applications, while the slotted and drilled face supports more even pad interaction under braking. The 830-42045L is a practical choice for drivers replacing a worn rear disc rotor on a Jeep Grand Cherokee or Jeep Grand Cherokee L with the specified vented rear disc setup.

DFC Geoperformance Rotor - Drilled and Slotted refers to Dynamic Friction’s performance-oriented rotor line, which uses a directional surface design and protective finishes to balance braking function with corrosion resistance. The 830-42045L is built for buyers who want a direct replacement rotor with a more aggressive surface design than a plain disc brake rotor.

Common Uses

• Replacing a worn or scored rear-left brake rotor.
• Addressing brake pulsation caused by rotor surface wear.
• Restoring braking performance after heat checking or corrosion.
• Servicing a vented rear disc brake setup on the listed Jeep applications.

Installation Notes

Verify rotor dimensions, bolt pattern, and center bore before installation. Confirm the vehicle uses the listed rear-left configuration and vented rear disc setup. Clean the hub mounting surface thoroughly to help prevent runout issues during brake service.

Quality Assurance

Dynamic Friction’s Geoperformance rotor line is built around application-specific rotor design, corrosion protection, and a directional braking surface for the listed fitments.
