Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line
The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to optimize braking performance. This design helps to evacuate heat, water, and brake dust more efficiently than standard rotors. The silver zinc coating on the rotor hat provides enhanced corrosion resistance, extending the rotor's service life especially in harsh environments.
Technical Specifications and Features
This disc brake rotor features a vented design that improves airflow to reduce heat buildup during braking. The directional surface pattern, combining drilled holes and slots, aids in maintaining consistent brake pad contact and reduces the risk of brake fade. The rotor measures 323 mm in outside diameter with an overall height of 130.9 mm, fitting precisely on Dodge Ram 2500 and Ram 3500 models. The rotor’s nominal thickness is 30 mm, with a discard thickness of 28.39 mm, ensuring safe replacement intervals. The zinc silver hat finish and rust-resistant coating protect against corrosion, while the eight 17 mm bolt holes and matching stud/lug hole pattern ensure secure mounting.
Applications and Problem Solving
- Replaces worn or warped rotors on Dodge Ram 2500 and Ram 3500
- Improves braking performance under heavy load or towing conditions
- Reduces brake fade caused by excessive heat buildup
- Minimizes rust and corrosion for longer rotor life
- Enhances brake pad cleaning and debris removal with drilled and slotted design
Installation Notes and Tips
Ensure the rotor surface is clean and free of contaminants before installation. Verify the bolt hole pattern and diameter match the vehicle specifications. Use proper torque settings on the eight lug bolts to secure the rotor. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Check rotor thickness regularly and replace when reaching discard thickness of 28.39 mm.
Quality Assurance
Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Dodge Ram 2500 and Ram 3500 vehicles. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion resistance.
