Stoptech Brake Rotor

Fits 2007–2010 GMC Sierra with Rear Drum Brakes and 2007–2009 GMC Yukon Rear Left Side

Part #: 127.66065L

Overview

The StopTech Slotted & Drilled Rear Left Rotor is a direct replacement brake disc designed specifically for select GMC Sierra and Yukon models. Engineered to work seamlessly with factory brake systems and stock calipers, this rotor enhances your vehicle’s braking performance while maintaining a clean, aggressive appearance behind your wheels. Ideal for drivers seeking improved braking reliability and heat management, this rotor supports safer stops in both wet and dry conditions.

Built for durability and consistent performance, this rotor is well-suited for daily driving and moderate performance use, providing peace of mind through enhanced pad bite and reduced brake fade.

Key Features

This StopTech rotor offers a combination of advanced design and quality materials to improve braking efficiency and longevity:

• One-piece direct replacement rotor designed for factory brake systems and stock calipers
• Cross-drilled holes and precision slots help disperse heat and brake dust, reducing pad glazing
• Black e-coating provides corrosion resistance for extended rotor life
• High carbon metallurgy (in most applications) promotes quieter braking and better crack resistance
• Improves wet and dry braking performance by enhancing pad bite and heat dissipation
• Maintains a stylish appearance behind wheels with a clean, performance-oriented look

Construction & Design

The rotor’s drilled and slotted design is engineered to optimize heat and gas evacuation during braking, which helps maintain consistent stopping power and reduces the risk of brake fade. The black e-coating finish not only protects against rust and corrosion but also contributes to quieter operation by minimizing surface imperfections. The use of high carbon metallurgy in most applications enhances structural integrity, providing resistance to cracking and warping under stress.

Installation & Fitment

This rotor is designed as a direct bolt-on replacement for the rear left side of 2007–2010 GMC Sierra models equipped with rear drum brakes and 2007–2009 GMC Yukon vehicles. Installation requires no modifications and fits with existing factory hardware and stock calipers, making it a straightforward upgrade for improved braking performance.
