Centric 320.65085F Disc Brake Rotor - Rear

Centric GCX Rear Brake Rotor Protection

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.65085F, is built for rear brake service on select Ford, Lincoln, and Expedition applications. It combines OE-style fitment with a fully coated finish to help resist rust on exposed surfaces while maintaining the braking surface needed for consistent stopping performance.

• Fully coated disc finish with Centric RS200 protection on non-mating surfaces
• Application-specific coating pattern matched to brake pad friction type
• High-carbon metallurgy selected to mirror OEM rotor profiles
• Smooth, solid rear rotor design
• Coated hat finish for added corrosion resistance
• 5-lug mounting pattern with 13.150 in. outside diameter

Product Line Details

Centric’s GCX Elemental Protection rotor line is engineered around vehicle-specific metallurgy and coating patterns rather than a one-size-fits-all design. For this part number 320.65085F, the goal is to deliver a rear disc brake rotor that matches the original equipment profile for the Ford F-150, Ford Expedition, Lincoln Navigator, and Lincoln Blackwood applications listed below.

Detailed Description

This rear disc brake rotor measures 13.150 inches in outside diameter, 2.217 inches in overall height, and 0.559 inches nominal thickness, with a 0.472 inch discard thickness. It uses a smooth surface type, solid rotor construction, and a 3.445 inch center hole diameter. The rotor is fully coated on non-mating surfaces and finished with a coated hat to help reduce rust and corrosion during daily use and seasonal exposure. Part number 320.65085F is designed for rear axle applications on 1999-2004 Ford F-150, 1999-2002 Ford Expedition, 2000-2002 Lincoln Navigator, and 2002 Lincoln Blackwood models listed in the fitment data.

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

What This Rotor Helps Address

• Rear brake pulsation caused by worn or uneven rotor surfaces
• Rust buildup on exposed rotor areas and hat surfaces
• Brake noise related to corrosion or surface wear
• Reduced braking consistency from rotor thickness loss
• OE replacement needs for rear brake service on Ford F-150, Expedition, Navigator, and Blackwood models

Installation Notes and Tips

Verify rear axle fitment by year, model, and production date before installation. This rotor is listed for 5-lug rear applications and includes no ABS tone ring or bearings. Confirm the vehicle uses a solid rear disc rotor with the specified dimensions before ordering. For best results, inspect pads, calipers, and hub surfaces during brake service and follow the vehicle manufacturer’s bedding procedure after installation.

Quality Assurance

Centric designs GCX rotors to match OE performance targets while using corrosion-resistant coatings and metallurgy aligned to the vehicle application. The part number 320.65085F is built to the dimensional and material profile required for the listed rear brake applications.
