Dynamic Friction 820-48050L Disc Brake Rotor - Front Left

Overview

This Dynamic Friction DFC Geoperformance Rotor - Drilled, part number 820-48050L, is a vented disc brake rotor built for specific front-left applications. It combines a drilled surface with a directional braking face and rust-resistant coating for consistent service in demanding brake systems.

Compatible with Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon applications, this rotor is specified for vehicles that use a 330 mm disc or the listed caliper and bracket configurations. The 820-48050L is a direct-fit replacement for the confirmed applications below.

Key Features

• Vented rotor construction for improved heat management.
• X-drilled surface and directional brake face for performance-oriented braking.
• Rust-resistant coating with Geospec silver gray hat finish.
• 330 mm outside diameter with 6-lug, 6-bolt-hole layout.
• Plain disc finish with 55 mm overall height and 78.5 mm center hole diameter.

Detailed Description

The Dynamic Friction 820-48050L is engineered as a drilled brake rotor for front-left fitments across a wide range of GM full-size SUVs, pickups, and vans. Confirmed applications include Cadillac Escalade and Escalade ESV, Chevrolet Suburban, Tahoe, Silverado 1500, Avalanche, Express 1500, and GMC Yukon, Yukon XL, Sierra 1500, and Savana 1500. Fitment notes also identify specific caliper and bracket configurations on certain model years, including dual-piston front calipers and casting-number requirements.

As part of the DFC Geoperformance Rotor - Drilled line, this rotor uses a vented design with directional X-drilled surface geometry to support brake cooling and surface consistency. The rust-resistant coating and Geospec silver gray hat finish add corrosion protection and a clean installed appearance. Part number 820-48050L is listed for front-left use only, so application matching should follow the exact year, make, model, and note details shown in the fitment data.

Common Uses

• Replacing a worn or below-spec front brake rotor.
• Addressing brake pulsation caused by rotor wear or surface variation.
• Restoring braking performance after heat checking or scoring.
• Matching a drilled rotor specification on listed GM applications.
• Correcting fitment issues tied to caliper, bracket, or disc-size requirements.

Installation Notes

Verify the vehicle’s year, make, model, and fitment notes before installation. This rotor is listed for front-left applications only, and some vehicles require specific caliper or bracket casting numbers, dual-piston front calipers, or a 330 mm disc specification. Confirm hub and brake system measurements against the published dimensions, including bolt circle diameter, center hole diameter, and overall height.

Quality Assurance

Dynamic Friction supplies brake components with application-specific engineering and corrosion-resistant finishes. The 820-48050L is built to the published dimensional and surface specifications for the listed fitments, including the DFC Geoperformance Rotor - Drilled design.
