Technical Description and Specifications

This disc brake rotor features a vented design with 93 pillar-style vanes, which improves airflow and heat dissipation during braking. The rotor’s nominal thickness is 1.256 inches (31.9 mm), with a discard thickness of 1.181 inches (30 mm), ensuring safe replacement intervals. The rotor has a smooth surface finish and a floating disc mounting style, which helps reduce stress and warping under heavy braking conditions. The overall height measures 2.902 inches (73.7 mm), and the outside diameter is 11.811 inches (300 mm). It includes five stud/lug holes with a diameter of 0.693 inches (17.6 mm) arranged on a 5.118 inch (130 mm) bolt circle diameter, compatible with Ram ProMaster 1500, 2500, 3500, and ProMaster Rapid models.

Applications and Problem Solving

• Replacement for worn or warped rotors on Ram ProMaster 1500, 2500, 3500, and ProMaster Rapid
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Prevents corrosion-related rotor damage in humid or salty environments
• Improves heat dissipation to reduce brake fade during heavy use
• Restores braking performance and pedal feel for commercial and fleet vehicles

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (1.181 inches) before installation
• Clean hub surface and mounting area to prevent runout and vibration
• Use proper torque specifications on lug nuts to avoid rotor warping
• Check compatibility with ABS sensors as this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to ensure optimal rotor performance
