Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors line is designed to provide enhanced braking performance for street and light track use. The 126.66008SR rotor features a vented design with straight vanes that promote efficient heat dissipation, reducing the risk of brake fade during demanding driving conditions. The slotted surface pattern improves pad contact and helps channel away dust, gas, and water, maintaining consistent braking response. The rotor’s coated hat finish offers protection against rust and corrosion, which is critical for maintaining rotor integrity over time. This rotor is specifically engineered for Chevrolet and GMC K1500 trucks, ensuring proper fitment with a center hole diameter of 3.094 inches (78.6 mm) and a floating disc mounting system that accommodates thermal expansion and contraction.

Applications and Problem Solving

• Improves braking performance on Chevrolet and GMC K1500 trucks
• Reduces brake fade during heavy or repeated braking
• Minimizes rotor warping caused by heat buildup
• Enhances pad bite and braking consistency in wet or dusty conditions
• Prevents premature rotor corrosion with coated hat finish

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.963 inches (24.46 mm) before installation. The rotor mounts using a 6-lug pattern with a 5.5 inch (139.7 mm) bolt circle diameter. No ABS tone ring or bearings are included, so verify compatibility with your vehicle’s existing components. Proper torque specifications should be followed when mounting the rotor to avoid warping. It is recommended to inspect brake pads and hardware during installation for optimal performance.
