• Nominal thickness of 0.787 inches (20.000 mm) with discard thickness at 0.728 inches (18.500 mm)
• Overall diameter of 13.701 inches (348.000 mm) and height of 3.386 inches (86.000 mm)
• Designed for 6-lug wheel configurations with a 5.315 inch (135.000 mm) bolt circle diameter

Product Line Details: StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on performance-oriented rotors that combine cross-drilled holes and precision slots. This design improves brake pad bite and helps evacuate gases, dust, and water from the rotor surface. The vented construction with straight vanes enhances airflow to reduce heat and minimize brake fade, making these rotors suitable for trucks like the Ford F-150 and Lincoln Mark LT that demand consistent braking under load.

Technical Specifications and Features

These rotors have a nominal thickness of 0.787 inches (20.000 mm) and a discard thickness of 0.728 inches (18.500 mm), ensuring they meet safety standards for replacement. The coated hat finish protects against rust and corrosion, which is critical for vehicles exposed to harsh weather or road conditions. The rotor’s overall height is 3.386 inches (86.000 mm), and the outside diameter measures 13.701 inches (348.000 mm), designed specifically for the brake system of Ford F-150 and Lincoln Mark LT models. The rotor is vented with straight vanes to optimize cooling efficiency during braking.

Applications and Problem Solving

• Improves brake cooling to reduce fade during heavy towing or hauling
• Enhances braking performance in wet or dusty conditions by evacuating debris
• Reduces rotor warping caused by excessive heat buildup
• Restores braking efficiency on Ford F-150 and Lincoln Mark LT trucks with worn or damaged rotors
• Provides consistent pedal feel and stopping power for daily driving and light performance use

Installation Notes and Tips

Installation of the StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor (127.65102L) requires proper torque specifications for the 6-lug wheel setup with a 5.315 inch (135.000 mm) bolt circle diameter. Ensure the rotor surface is clean and free of contaminants before mounting. Since these rotors do not include bearings or ABS tone rings, verify compatibility with your vehicle’s existing components. It is recommended to replace brake pads simultaneously to maximize braking performance and rotor lifespan.
