• Nominal thickness of 22 mm with a discard thickness of 20.4 mm
• Rust-resistant coating for extended rotor life
• Geospec silver grey hat finish for corrosion resistance
• 6 bolt holes with 17 mm diameter and 139.7 mm bolt circle diameter
• Outside diameter of 375 mm and height of 53.44 mm

Detailed Product Features and Specifications

This Dynamite Friction rotor features a directional surface type that is both drilled and slotted, designed to enhance braking efficiency by improving heat dissipation and reducing brake fade. The rotor's nominal thickness is 22 mm, with a discard thickness of 20.4 mm, ensuring it meets safety standards for wear limits. The rotor includes six bolt holes, each with a 17 mm diameter, arranged on a 139.7 mm bolt circle diameter, making it compatible with Ram 1500 brake assemblies. The hat section is finished in Geospec silver grey, providing additional corrosion resistance alongside the rust-resistant coating applied to the rotor surface. With an outside diameter of 375 mm and a height of 53.44 mm, this rotor fits precisely within the specified brake system dimensions.

About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted product line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a directional design. This configuration is intended to optimize brake pad contact, improve water and debris evacuation, and enhance cooling during heavy braking. The Geospec silver grey hat finish and rust-resistant coating contribute to durability, making these rotors suitable for trucks like the Ram 1500 that may encounter varied driving conditions.

Applications and Problem Solving

• Reduces brake fade during towing or heavy load conditions
• Improves heat dissipation for consistent braking performance
• Minimizes rust and corrosion on rotor surfaces
• Enhances water and debris removal to maintain pad contact
• Maintains structural integrity within specified thickness limits

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20.4 mm before installation. Verify compatibility with Ram 1500 brake assemblies using the 6-bolt pattern and 139.7 mm bolt circle diameter. Clean the rotor surface to remove any protective coatings before mounting to ensure optimal pad contact. Follow manufacturer torque specifications for bolt installation to maintain rotor alignment and safety.

Quality Assurance and Warranty

Dynamite Friction manufactures the 830-40121R rotor to meet industry standards for disc brake rotors. The rust-resistant coating and Geospec silver grey hat finish contribute to long-term durability. Warranty details should be confirmed with the product documentation or supplier, as they may vary by region or distributor.
