Product Details and Fitment

This DFC Brake Rotor - Drilled and Slotted - Silver is built around the listed dimensions and mounting pattern to match the front left brake position on the supported vehicles. It is a direct-fit disc brake rotor for Chevrolet Trailblazer and GMC Envoy platform vehicles, along with Buick Rainier, Isuzu Ascender, Chevrolet SSR, GMC Envoy XUV, and Saab 9-7x applications.

Part number 631-48046L is a fitment-specific rotor for drivers replacing a worn, warped, or corroded front left rotor on these platforms. The directional slotted and drilled face supports stable braking performance under repeated stops while maintaining the correct rotor geometry for the application.

• Brake pulsation from rotor wear or thickness variation
• Visible rotor rust on the braking surface or hat area
• Noise caused by uneven rotor wear
• Reduced braking consistency from heat buildup
• Service replacement for front left rotor wear on the listed GM and Saab vehicles

Installation Notes and Quality

Verify rotor dimensions, bolt pattern, center hole diameter, and front left position before installation. Clean the hub mounting surface and inspect pads, caliper condition, and wheel hardware for wear before fitting the new rotor. Because this rotor uses a directional brake surface, install it on the specified side only.

Dynamic Friction supplies this rotor as a fitment-specific brake component for the listed applications. The part number 631-48046L should be matched to the vehicle’s brake configuration and rotor dimensions before service.
