Detailed Product Description

This Dynamite Friction disc brake rotor is designed to meet the demands of heavy-duty Chevrolet Sierra 3500 HD and GMC Silverado 3500 HD trucks. The rotor’s 355 mm outside diameter and 40 mm nominal thickness provide a robust braking surface capable of handling high loads. The directional slotted and drilled surface improves brake pad bite and helps dissipate heat and gases generated during braking, reducing the risk of brake fade under heavy use.

The rotor’s hat is finished in Geospec silver grey, which along with the rust resistant coating, helps protect against corrosion and extends the rotor’s service life. With eight bolt holes sized at 16.2 mm diameter and a bolt circle diameter of 180 mm, this rotor is designed for secure mounting and precise fitment. The center hole diameter of 144.1 mm and height of 150.2 mm ensure compatibility with the specified truck models.

The DFC Geoperformance Rotor - Drilled and Slotted line from Dynamite Friction focuses on delivering rotors with enhanced thermal management and durability. This product line is engineered to provide consistent braking performance in demanding conditions, making it suitable for heavy-duty applications like the Chevrolet Sierra 3500 HD and GMC Silverado 3500 HD.

Applications and Problem Solving

• Improves braking performance for heavy-duty Chevrolet and GMC trucks
• Reduces brake fade during extended or heavy braking
• Minimizes rotor warping caused by heat buildup
• Protects against rust and corrosion for longer rotor life
• Ensures precise fitment for Sierra 3500 HD and Silverado 3500 HD models

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the bolt hole alignment and center hole diameter match the vehicle hub. Use proper torque specifications for the eight lug bolts to avoid rotor distortion. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.

Quality Assurance

Dynamite Friction rotors undergo rigorous quality control to meet industry standards for durability and performance. The rust resistant coating and Geospec silver grey hat finish contribute to corrosion resistance.
