Stoptech 126.66025SL Disc Brake Rotor - Front Left

Overview

StopTech Sport Slotted Disc Brake Rotor 126.66025SL is a 1-piece direct replacement rotor for factory brake systems and stock calipers. It is built for drivers who want stronger braking response, better heat management, and corrosion protection in a vented, slotted design.

Compatible with Chevrolet and GMC truck and SUV applications, this rotor is engineered for fitment on the front left position and supports consistent braking performance in daily driving and demanding stop-and-go use.

Key Features

• Slotted surface helps move heat and brake dust away from the pad contact area.
• Vented rotor construction supports improved cooling during repeated stops.
• Black e-coating helps protect exposed surfaces from corrosion.
• High-carbon metallurgy is used in most applications for quieter operation and improved crack resistance.
• 1-piece direct replacement design works with factory brake systems and stock calipers.
• ABS tone ring included for applications that require it.

Detailed Description

StopTech 126.66025SL is part of the StopTech Sport Slotted Disc Brake Rotors line, a product family focused on direct-fit brake disc replacement with performance-oriented slotting. The slot pattern is intended to improve pad bite, reduce glazing, and maintain more stable braking in wet and dry conditions. The coated hat finish adds another layer of corrosion resistance, while the vented rotor design helps manage operating temperatures.

This rotor is a practical upgrade for Chevrolet Express 1500, Chevrolet Tahoe, Chevrolet C1500, Chevrolet C1500 Suburban, GMC Savana 1500, GMC C1500, GMC C1500 Suburban, and GMC Yukon applications listed in the fitment data. If you are replacing a worn front brake rotor on a Chevrolet Tahoe or GMC Yukon, 126.66025SL provides a direct replacement format that matches factory brake system requirements.

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

Common Problems It Can Address

• Brake fade during repeated stops
• Brake pad glazing
• Excess brake dust buildup on the rotor surface
• Corrosion on exposed rotor surfaces
• Reduced braking bite in wet or dry conditions
