Dynamic Friction 810-40094L Disc Brake Rotor - Front Left

Overview

The Dynamic Friction DFC Geoperformance Rotor - Slotted, part number 810-40094L, is a vented disc brake rotor built for front left applications on select Ram, Dodge, and Chrysler trucks and SUVs. It combines a slotted braking surface with a directional design to support consistent pad contact and controlled heat management.

Compatible with Ram 1500, Ram 1500 Classic, Dodge Ram 1500, Dodge Durango, and Chrysler Aspen applications, this rotor is finished with a Geospec Silver Grey hat and a rust-resistant coating for added surface protection. The 810-40094L is engineered for vehicles that use a 5-lug, 139.7 mm bolt pattern.

Key Features

• Slotted, directional brake surface for more consistent pad interaction.
• Vented rotor construction for improved airflow through the disc.
• Rust-resistant coating helps protect exposed surfaces.
• Geospec Silver Grey hat finish for a clean, corrosion-conscious appearance.
• 5-lug design with 139.7 mm bolt circle and 336 mm outside diameter.

Detailed Description

The DFC Geoperformance Rotor - Slotted line is focused on brake performance and durability in demanding daily driving conditions. This rotor uses a plain disc finish with a slotted braking surface and directional vane layout, giving the brake system a more controlled friction interface while helping manage heat buildup during repeated stops. The 810-40094L also uses a vented rotor design, 28 mm nominal thickness, and 26.4 mm discard thickness for service planning.

Fitment includes 2019-2024 Ram 1500 Classic, 2011-2018 Ram 1500, 2009-2010 Dodge Ram 1500, 2002-2005 Dodge Ram 1500, 2007-2009 Chrysler Aspen, 2004-2009 Dodge Durango, and 2006-2008 Dodge Ram 1500 with 5 lug wheels. If you are replacing a front left brake rotor on a Ram 1500 or Dodge Ram 1500, confirm the rotor dimensions and bolt pattern before installation.

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

What It Helps Address

• Uneven brake pad contact on worn or damaged rotors.
• Heat buildup during repeated braking.
• Surface corrosion on exposed rotor areas.
• Brake pulsation caused by rotor wear beyond discard thickness.
• Fitment issues on 5-lug front left brake rotor applications.

Installation Notes

Verify the 336 mm outside diameter, 78.5 mm center hole diameter, 139.7 mm bolt circle, and 17 mm bolt hole diameter before installation. This rotor is listed for front left placement only, so match the position exactly when servicing Ram 1500, Ram 1500 Classic, Dodge Ram 1500, Dodge Durango, or Chrysler Aspen brake systems.

Quality Assurance

Dynamic Friction designs the DFC Geoperformance Rotor - Slotted line with corrosion protection and application-specific dimensions for direct replacement use on listed vehicles. Part number 810-40094L is built to match the specified fitment and braking geometry for the covered applications.
