Designed specifically for the front disc brakes of the Highlander, RX350, and RX350h, this rotor offers durability and consistent stopping power.

• Full cast construction for strength and durability
• Geomet rust-resistant coating to reduce corrosion
• Vented rotor design for improved heat dissipation
• Nominal thickness of 28.0 mm with a discard thickness of 25.0 mm
• Outside diameter of 340.0 mm and 5 lug holes with 114.3 mm bolt circle diameter
• Smooth surface type for consistent pad contact
• Overall height of 49.1 mm

Detailed Product Description

This disc brake rotor is constructed as a full cast unit, providing the necessary strength to withstand the demands of daily driving and braking. The vented design enhances airflow, helping to dissipate heat more effectively and reduce brake fade during extended use. The Geomet coating applied to the rotor surface offers rust resistance, which is especially beneficial in humid or wet environments, extending the rotor's service life.

The rotor measures 340.0 mm in outside diameter and features a nominal thickness of 28.0 mm, with a discard thickness set at 25.0 mm to ensure safe replacement intervals. It includes five lug holes arranged on a 114.3 mm bolt circle diameter, matching the factory specifications for Lexus Highlander and Toyota RX350/RX350h front brakes. The smooth surface finish promotes even brake pad wear and consistent braking performance.

About the Power Stop - Front Genuine Geomet Coated Rotor Line

The Power Stop - Front Genuine Geomet Coated Rotor line focuses on providing rotors with a factory-style Geomet coating that resists rust and corrosion. This coating helps maintain rotor integrity and appearance over time, reducing the likelihood of surface rust that can affect braking efficiency. These rotors are designed as standard replacement parts, meeting OEM specifications for fit and function on compatible vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped front rotors on Lexus Highlander and Toyota RX350/RX350h
• Addresses brake noise caused by uneven rotor surfaces
• Helps reduce brake fade from overheating during extended braking
• Prevents rust buildup that can lead to uneven pad contact
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor is installed on the front axle of compatible Lexus Highlander or Toyota RX350/RX350h models. Verify the rotor thickness before installation; replace if below the discard thickness of 25.0 mm. Clean the rotor surface and hub mounting area to remove any debris or rust before mounting. Use proper torque specifications for the 5 lug nuts on the 114.3 mm bolt circle diameter to ensure secure fitment.

Quality Assurance

Power Stop rotors are manufactured to meet or exceed OEM standards for durability and performance. The Geomet coating provides additional corrosion resistance to extend rotor life. While specific warranty details are not provided, Power Stop products typically undergo rigorous quality control to ensure reliability and consistent braking performance.
