• Directional brake surface for correct side-specific installation

Product Details

This DFC Brake Rotor - Drilled and Slotted - Silver is engineered as a direct-fit front right rotor for vehicles that use a 328 mm vented disc with a 62 mm center hole and 14.5 mm stud/lug holes. It is compatible with 2018-2021 Lexus NX300 front right, 2015-2021 Lexus NX300h front right, 2015-2017 Lexus NX200t front right, 2010-2015 Lexus RX350 front right, 2010-2015 Lexus RX450h front right, 2011-2020 Toyota Sienna front right, and 2008-2019 Toyota Highlander front right. The directional slotted and drilled surface supports even pad interaction and helps maintain a consistent braking feel during routine street use.

The silver zinc hat finish adds corrosion resistance where the rotor mounts to the hub, while the plain disc finish and vented construction support heat management in normal braking conditions. If you are replacing a worn front right rotor on a Lexus NX300, Toyota Highlander, or Toyota Sienna, 631-76138R provides the fitment and dimensions needed for a proper service replacement.

Common Issues This Rotor Addresses

• Brake pulsation from a rotor that has exceeded discard thickness
• Uneven braking feel caused by worn or heat-affected rotor surfaces
• Visible rotor corrosion on the hat area
• Noise or vibration associated with rotor wear
• Front right rotor replacement on listed Lexus and Toyota models

Installation Notes and Tips

Verify rotor diameter, thickness, bolt pattern, and directional orientation before installation. This rotor is listed for the front right position only, so confirm side-specific placement during service. Clean the hub mounting surface before installing the rotor, and inspect pads, caliper hardware, and wheel bearings for wear that could affect braking performance.

Quality Assurance

Dynamite Friction supplies this rotor with a rust resistant coating and zinc silver hat finish to support corrosion resistance in service. Part number 631-76138R is built to match the listed OE-style dimensions for the specified Lexus and Toyota front right applications.
