The premium finish supports long-term performance and reduces the risk of rust-related issues on Chevrolet Tahoe brake components.

Technical Specifications and Features

This disc brake rotor is vented to facilitate better airflow and heat dissipation during braking, which helps prevent brake fade under demanding conditions. The smooth surface type ensures consistent pad contact and braking efficiency. With an overall height of 2.185 inches (55.5 mm), the rotor fits precisely within the brake assembly of compatible Chevrolet Tahoe models. The six mounting bolt holes and specific bolt circle diameter provide secure installation and alignment.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Chevrolet Tahoe vehicles
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps restore braking performance diminished by rotor thickness below discard limits
• Prevents corrosion-related rotor damage with Gray Armor-Plate coating
• Improves heat management during heavy braking to reduce fade

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 1.181 inches (30.0 mm). The discard thickness is 1.102 inches (28.0 mm), and rotors below this thickness should be replaced. Verify the mounting bolt hole pattern and center hole diameter match the vehicle specifications. Proper torque on mounting bolts is essential to avoid rotor warping.
