Dynamic Friction 830-40045R Disc Brake Rotor - Front Right

Overview

This Dynamic Friction DFC Geoperformance Rotor - Drilled and Slotted is a vented disc brake rotor built for front right applications with directional braking surfaces. It is a fitment-specific replacement for heavy-duty Chevrolet, GMC, and Dodge trucks and SUVs, including Chevrolet K2500, GMC K3500, and Dodge Ram 2500 applications.

Part number 830-40045R identifies this rotor in the DFC Geoperformance line. The drilled and slotted surface, rust-resistant coating, and Geospec Silver Grey hat finish support consistent braking performance and corrosion protection.

Key Features

• Drilled and slotted braking surface for improved pad bite and heat management.
• Vented rotor construction for airflow through the disc.
• Rust-resistant coating for added protection against corrosion.
• Geospec Silver Grey hat finish for a clean, finished appearance.
• Directional brake surface for application-specific installation.
• Fits heavy-duty truck and SUV brake systems with 8-lug and axle-specific configurations.

Detailed Description

The 830-40045R rotor is engineered around the listed fitments and dimensions, including a 317.5 mm outside diameter, 32.9 mm nominal thickness, 30.86 mm discard thickness, 70 mm overall height, 137.4 mm center hole diameter, and 165.1 mm bolt circle diameter. Its 8-bolt and 8-stud/lug hole layout supports the specified applications, while the directional slotted and drilled face is suited to demanding braking conditions.

Compatible With Chevrolet K2500, Chevrolet K3500, Chevrolet Suburban 1500, Chevrolet Suburban 2500, GMC K2500, GMC K3500, GMC K1500 Suburban, GMC K2500 Suburban, and Dodge Ram 2500 applications listed in the fitment data. This part number 830-40045R is also a useful reference when matching the correct rotor for Chevrolet K2500 and GMC K3500 brake service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake pulsation from worn or uneven rotor surfaces.
• Reduced braking consistency under repeated stops.
• Corrosion on exposed rotor surfaces.
• Fitment issues on axle- and hub-specific brake setups.
• Noise and vibration caused by rotor wear.

Installation Notes

Verify rotor dimensions, hub hole size, bolt circle, and axle configuration against the vehicle listing before installation. This rotor is listed for front right placement only, so confirm the correct side and position during brake service. Clean mating surfaces and inspect pads, caliper condition, and hardware wear before completing the repair.

Quality Assurance

Dynamic Friction’s DFC Geoperformance Rotor line combines drilled and slotted surface design with a rust-resistant coating and vented construction for application-specific brake service.
