About StopTech Sport Slotted Disc Brake Rotors

The StopTech Sport Slotted Disc Brake Rotors line is designed to provide enhanced braking performance for trucks and performance vehicles. Featuring a slotted surface, these rotors help evacuate gases, dust, and water from the braking surface, improving pad bite and reducing brake fade. The vented rotor design promotes better heat dissipation, which is critical for heavy-duty applications like those found in Dodge Ram 2500 and 3500 trucks. The coated hat finish adds corrosion resistance, extending rotor life in harsh environments.

Technical Details and Specifications

This StopTech rotor has an overall height of 102 mm (4.016 inches) and a center hole diameter of 123 mm (4.843 inches). It includes eight stud/lug holes with a diameter of 16.7 mm (0.657 inches) arranged on a 165 mm (6.496 inches) bolt circle diameter. The rotor weighs approximately 39 lbs (17.73 kgs), balancing durability and performance. The floating disc mounting allows for thermal expansion, reducing the risk of warping during heavy braking. The straight vane style enhances airflow through the rotor, aiding in heat management during extended use.

Applications and Problem Solving

• Improves braking performance on Dodge Ram 2500 and 3500 trucks
• Reduces brake fade during heavy towing or hauling
• Minimizes rotor warping caused by thermal stress
• Enhances pad bite and braking consistency in wet or dusty conditions
