Dynamic Friction 631-67075L Disc Brake Rotor - Front Left

Overview

This Dynamic Friction disc brake rotor is built for specific Nissan 620 and Nissan 720 front left applications. The 631-67075L combines a slotted and drilled surface with a zinc silver hat finish and rust-resistant coating for a clean, service-focused replacement.

Key Features

• Slotted and drilled brake surface for consistent pad contact and heat management.
• Solid rotor construction with a plain disc finish.
• Zinc silver hat finish with rust-resistant coating.
• 6-lug design with a 103 mm bolt circle.
• Directional braking surface for application-specific fitment.

Detailed Description

The Dynamic Friction 631-67075L is a disc brake rotor engineered around the listed Nissan fitments, including Nissan 620 and Nissan 720 front left applications. Its solid rotor design, 271 mm outside diameter, and 43.3 mm overall height align with the specified vehicle requirements, while the drilled and slotted surface supports more even pad interaction under braking. The zinc silver hat finish and rust-resistant coating add corrosion protection where exposed metal is a concern. This part number, 631-67075L, is a direct-fit style replacement for the confirmed applications shown in the fitment data.

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

What It Helps Address

• Brake pulsation caused by worn or uneven rotor surfaces.
• Reduced braking consistency from heat buildup.
• Corrosion on exposed rotor surfaces and hat areas.
• Noise or uneven pad contact related to rotor wear.

Installation Notes

Verify rotor dimensions, bolt circle, center hole diameter, and directional orientation before installation. Confirm the vehicle production date notes for Nissan 720 applications, since several 1981 and 1982 listings are date-specific. Professional installation and brake system inspection are recommended whenever replacing rotors.

Quality Assurance

Dynamic Friction identifies this rotor with a rust-resistant coating and corrosion-protective hat finish for service durability. Confirm part number 631-67075L against the vehicle’s exact fitment details before ordering.
