Centric 320.35048H Disc Brake Rotor - Rear

Rear Brake Rotor for Mercedes-Benz and Chrysler

Centric GCX Elemental Protection Disc Brake Rotor 320.35048H is a rear disc brake rotor built for OE-style fitment and corrosion resistance. It is engineered for vehicles such as the Mercedes-Benz SLK55 AMG, CLK550, C350, C55 AMG, CLK500, C32 AMG, CLK55 AMG, SLK32 AMG, E430, E55 AMG, C43 AMG, and the Chrysler Crossfire.

The fully coated finish helps protect non-mating surfaces from rust, while the high-carbon rotor metallurgy is selected to match OEM-style brake performance and thermal characteristics. For drivers searching for a rear brake rotor for Mercedes-Benz C55 AMG or a rear rotor for Chrysler Crossfire, this Centric GCX rotor is built to meet the application-specific requirements of the vehicle.

Product Line Details

Centric GCX Elemental Protection Disc Brake Rotors are application-specific rotors designed around both coating pattern and rotor metallurgy. The GCX line uses Centric’s RS200 finish on non-mating surfaces to help resist rust and corrosion, while the alloy selection is matched to the vehicle’s OEM metallurgical profile. That approach supports consistent brake feel and long-term appearance on rear brake rotor replacements for Mercedes-Benz and Chrysler applications.

Detailed Description

Centric 320.35048H is a rear vented brake rotor with a 300 mm outside diameter, 22.000 mm nominal thickness, and straight vane design. It uses a floating/DIH mounting configuration, a smooth friction surface, and a fully coated finish to help maintain surface protection in everyday driving conditions. This rotor is listed for 1998-2011 Mercedes-Benz and Chrysler rear applications, including performance models such as the Mercedes-Benz E55 AMG, C43 AMG, CLK55 AMG, and SLK55 AMG.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Rotor Can Address

• Rear brake rotor rust on exposed surfaces
• Brake pulsation caused by worn or below-spec rotors
• Reduced braking consistency from heat-stressed rotor material
• Noise or uneven pad contact from surface wear
• Replacement needs on Mercedes-Benz and Chrysler rear brake service

Installation Notes and Tips

Verify rotor diameter, center hole, bolt circle, and thickness before installation. Clean the hub mounting surface thoroughly so the rotor seats flat, and inspect brake pads and caliper condition at the same time. For fitment-specific searches, this rotor is used on rear brake service for 2005-2011 Mercedes-Benz SLK55 AMG, rear; 2007-2009 Mercedes-Benz CLK550, rear; and 2005-2006 Chrysler Crossfire, rear.

Quality Assurance

Centric designs GCX rotors to match OE performance targets and uses application-specific coating and metallurgy selection to support fitment accuracy and corrosion protection. Part number 320.35048H is built for the listed rear applications across the 1998-2011 model years.
