Centric 320.39032H Disc Brake Rotor - Front

Centric GCX Front Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.39032H, is a front vented rotor built for OE-style braking performance and corrosion resistance. It is a fitment-based replacement for select Volvo XC90 and Volvo S60 front brake applications, with a fully coated finish for added protection on exposed surfaces.

Centric’s GCX rotor line uses application-specific coating patterns and high-carbon metallurgy to better match original equipment requirements. For drivers searching for a front brake rotor for 2003-2014 Volvo XC90 or a 2008-2009 Volvo S60 front rotor, 320.39032H is built around those vehicle-specific dimensions and material targets.

Product Line Details

The Centric GCX Elemental Protection Disc Brake Rotors line is engineered to align with OE performance targets while adding corrosion protection on non-mating surfaces. Centric applies its RS200 finish in patterns matched to brake pad friction type, and the rotor metallurgy is selected to mirror OEM-style carbon content for the application. This helps maintain consistent fitment and appearance over time on vehicles such as the Volvo XC90 and Volvo S60.

Fitment

• Fits 2003-2014 Volvo XC90, front; 316 mm front disc; part number 320.39032H
• Fits 2008-2009 Volvo S60, front; 315.7 mm diameter; vented; part number 320.39032H

What This Rotor Helps Address

• Front brake pulsation caused by worn or uneven rotors
• Rust and corrosion on exposed rotor surfaces
• Reduced braking consistency from rotor wear beyond discard thickness
• Noise or vibration related to rotor surface condition
• Fitment issues when replacing an OE-style front rotor on Volvo XC90 or Volvo S60 models

Installation Notes and Tips

Verify rotor diameter, center hole size, bolt circle, and minimum thickness before installation. Clean the hub mounting surface thoroughly so the floating disc mounting seats evenly, and inspect pads and calipers for wear that could affect rotor life. Because this rotor is fully coated, avoid contaminating the friction surface during handling and installation.

Quality Assurance

Centric designs GCX rotors to match OE performance targets and uses application-specific coating and metallurgy selection for the vehicle platform. The brand states coverage across more than 1,000 SKUs for broad vehicle support, including select Volvo XC90 and Volvo S60 front brake applications.
