Overview

The Dynamic Friction 631-40012L is a rear left disc brake rotor for select Chrysler, Dodge, and Eagle applications. It uses a slotted and drilled surface with a zinc silver hat finish and rust-resistant coating for a service-focused replacement that matches the listed fitment.

This rotor is listed for Chrysler 300M, Chrysler Concorde, and Dodge Intrepid applications, with fitment notes that vary by performance package, wheel size, and front rotor size on certain models. The 631-40012L is built around the specified dimensions and bolt pattern for direct application matching.

Key Features

• Slotted and drilled rotor surface for consistent brake contact.
• Rust-resistant coating helps protect exposed surfaces.
• Zinc silver hat finish for a clean, corrosion-conscious appearance.
• Solid rotor construction with a directional braking surface.
• 5-lug pattern with 114.3 mm bolt circle and 73.6 mm center hole.

Detailed Description

The Dynamic Friction 631-40012L brake rotor is engineered for rear left fitment on a range of Chrysler, Dodge, and Eagle sedans from the 1990s and early 2000s. Its 270 mm outside diameter, 51.4 mm overall height, and 11.8 mm nominal thickness support the listed OE-style application requirements, while the 10.4 mm discard thickness provides the service limit reference for replacement planning. The slotted X-drilled surface and directional design are intended to maintain a consistent braking interface under repeated use.

For shoppers searching for a rear left brake rotor for Chrysler Concorde, Chrysler Intrepid, or Dodge Intrepid, part number 631-40012L matches the specified vehicle configurations in the fitment table. This part number 631-40012L also appears across multiple Chrysler 300M and Chrysler LHS applications, making it a targeted replacement for the listed platform variants.

What It Is Used For

• Brake pulsation caused by worn or uneven rotor surfaces.
• Reduced braking consistency from heat-affected rotor faces.
• Corrosion on the rotor hat or exposed metal surfaces.
• Replacement of a rotor that no longer meets thickness specifications.
• Service work on listed rear left brake applications for Chrysler and Dodge sedans.

Installation Notes and Tips

Verify the vehicle’s year, make, model, and listed notes before ordering. Several applications require matching the performance package, wheel size, or front rotor size noted in the fitment data. Confirm the 5-lug pattern, 114.3 mm bolt circle, and rear left position before installation.

Quality Assurance

Dynamic Friction supplies brake components for replacement applications with attention to fitment-specific dimensions and surface treatment. The 631-40012L is built with a rust-resistant coating and zinc silver hat finish to support long-term service in the listed applications.
