Product Details

This DFC Brake Rotor - Drilled and Slotted - Silver is engineered as a solid rear rotor with a plain disc finish and a directional braking surface. The 278 mm outside diameter, 33.3 mm overall height, and 15.7 mm bolt hole diameter align with the listed fitments for Jeep Cherokee and Chrysler 200 rear left brake service. The zinc silver hat finish and rust resistant coating help protect exposed surfaces from corrosion, while the drilled and slotted face supports more even pad interaction under repeated stops. Part number 631-42012L is listed for 2022 Jeep Cherokee rear left with single piston front calipers, 2014-2021 Jeep Cherokee rear left with Akebono 1-piston front calipers, and 2015-2017 Chrysler 200 rear left with 330 mm front rotors or 305 mm front rotors depending on configuration. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rear brake rotor wear or scoring
• Brake pulsation caused by rotor surface irregularities
• Corrosion on the rotor hat or exposed metal surfaces
• Reduced pad-to-rotor contact consistency
• Noise or vibration during rear brake service
