Designed with a directional slotted and drilled surface, this rotor enhances heat dissipation and helps maintain consistent stopping power under demanding conditions.

• Directional slotted and drilled surface for improved heat management
• Nominal thickness of 20 mm with a discard thickness of 18 mm
• Zinc silver hat finish with rust-resistant coating for corrosion protection
• 345 mm outside diameter and 53 mm height for precise fitment
• 6 bolt holes with 16 mm diameter and 139.7 mm bolt circle diameter
• Center hole diameter of 78.6 mm for accurate hub alignment

Detailed Product Features and Specifications

This disc brake rotor features a plain disc finish combined with a zinc silver hat finish that includes a rust-resistant coating, extending the rotor's service life by reducing corrosion. The rotor's surface is both drilled and slotted in a directional pattern, which aids in channeling away brake dust, gases, and water, improving braking consistency and reducing fade. With a nominal thickness of 20 mm and a discard thickness of 18 mm, this rotor meets strict wear standards to ensure safety and performance. The rotor is designed with six bolt holes, each 16 mm in diameter, arranged on a 139.7 mm bolt circle diameter, making it compatible with specific GM models.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize braking efficiency and rotor cooling. This product line is tailored for vehicles requiring enhanced heat dissipation and debris removal from the braking surface, which is particularly beneficial for trucks and SUVs used in towing or heavy-duty applications. The silver zinc coating on the rotor hat provides additional protection against rust, supporting durability in various driving environments.

Compatible Vehicles and Applications

This rotor is compatible with a range of GM vehicles, including:

• Cadillac Escalade and Escalade ESV
• Chevrolet Silverado 1500 and Silverado 1500 LTD
• Chevrolet Tahoe
• GMC Sierra 1500 and Sierra 1500 Limited
• GMC Yukon and Yukon XL

It is designed to address common braking issues such as:

• Brake fade during heavy towing or extended downhill driving
• Uneven rotor wear causing vibration or noise
• Corrosion-related rotor degradation
• Reduced braking efficiency due to heat buildup
• Brake dust accumulation affecting pad contact

Installation Notes and Tips

When installing the Dynamite Friction 631-47081L rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the rotor thickness is above the discard thickness of 18 mm to maintain safety standards. Proper torque specifications should be followed for the six lug bolts to ensure secure fitment. The directional slotted and drilled surface must be installed with the correct rotation direction for optimal performance.
