Detailed Product Description

This Power Stop rotor is part of the Power Stop - Front Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating. This coating offers enhanced rust resistance compared to standard rotors, helping to maintain rotor integrity and appearance over time. The vented rotor design improves heat dissipation during braking, reducing the risk of brake fade under heavy use. With precise dimensions including a 13.50-inch outside diameter and 6 lug holes on a 5.50-inch bolt circle, this rotor is engineered to meet OEM specifications for front brake applications.

Compatible Vehicles and Applications

This disc brake rotor is compatible with a range of full-size SUVs and trucks, including:

• Cadillac Escalade and Escalade ESV
• Chevrolet Silverado 1500 and Silverado 1500 LTD
• Chevrolet Tahoe
• GMC Sierra 1500 and Sierra 1500 Limited
• GMC Yukon and Yukon XL

It is designed to replace front rotors on these models, ensuring proper fitment and braking performance.

Common Issues Addressed by This Rotor

• Brake rotor rust and corrosion from road exposure
• Brake fade due to insufficient heat dissipation
• Warped or uneven rotor surfaces causing vibration
• Worn rotors below discard thickness affecting braking safety
• OEM rotor replacement for routine maintenance or repair

Installation Notes and Tips

When installing the Power Stop AR84103EVC rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the rotor thickness is above the discard thickness of 1.10 inches (28.00 mm) to maintain safe braking performance. Use proper torque specifications for the 6 lug bolts on the 5.50-inch bolt circle diameter. It is recommended to inspect brake pads and hardware during rotor replacement for optimal system performance.
