Technical Specifications and Features
This disc brake rotor is vented to allow better airflow and heat dissipation, which helps prevent overheating during heavy braking. The rotor's nominal thickness is 30 mm, with a discard thickness of 28.4 mm, indicating when replacement is necessary to maintain safe braking. The rotor features a directional surface type with both drilled holes and slots, which aids in debris removal and improves braking response. The hat finish is zinc silver, providing a rust-resistant coating to protect against corrosion. The rotor has 5 bolt holes, each with a diameter of 17.2 mm, arranged on a 139.9 mm bolt circle diameter, ensuring proper fitment on compatible Dodge Ram 1500 models.
Applications and Problem Solving
- Replacement rotor for worn or warped brake rotors on Dodge Ram 1500
- Improves heat dissipation to reduce brake fade during towing or heavy loads
- Enhances braking performance in wet conditions by evacuating water from the rotor surface
- Addresses brake noise and vibration caused by uneven rotor surfaces
- Prevents rust and corrosion buildup on the rotor hat for longer service life
Installation Notes and Tips
Ensure the rotor thickness is above the discard thickness of 28.4 mm before installation. Clean the rotor surface to remove any protective coatings or debris prior to mounting. Verify the 5-lug bolt pattern with 17.2 mm diameter holes and 139.9 mm bolt circle diameter matches your Dodge Ram 1500 specifications. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.
