Product Line Details

The Power Stop - Front OE Stock Replacement Brake Rotor line is designed to meet original equipment specifications for front disc brake rotors. This product line focuses on providing a direct fit replacement that maintains the factory braking feel and performance. The AR8771 rotor is part of this line, offering vented rotor construction to help manage heat buildup during braking, which is critical for heavy-duty applications like those found in Dodge Ram trucks.

Technical Specifications and Features

This disc brake rotor features a vented design that enhances airflow to reduce heat and prevent brake fade during extended use. The nominal thickness of 1.40 inches (35.50 mm) ensures structural integrity, while the discard thickness of 1.34 inches (34.00 mm) indicates the minimum safe thickness for rotor replacement. The rotor’s outside diameter of 13.90 inches (353.00 mm) and overall height of 4.00 inches (101.90 mm) are engineered to match OE dimensions for proper fitment and performance. The mounting bolt hole circle diameter of 6.50 inches (165.10 mm) with 8 stud/lug holes ensures secure installation on compatible Dodge Ram models.

Common Applications and Problem Solving

• Replacement for worn or warped front brake rotors on Dodge Ram 1500, 2500, and 3500
• Addresses brake pulsation caused by uneven rotor surfaces
• Restores braking efficiency lost due to rotor thickness below discard limits
• Improves heat dissipation to reduce brake fade during heavy towing or hauling
• Eliminates noise and vibration associated with damaged or corroded rotors

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 1.40 inches (35.50 mm). Clean the rotor surface and hub mounting area to prevent uneven contact and potential vibration. Use proper torque specifications for the 8 lug nuts to secure the rotor firmly. Since this rotor does not have a rust resistant coating, consider applying an anti-corrosion treatment if operating in harsh environments.
