The vented construction helps move air through the rotor body, while the smooth, plain face supports stable braking performance during routine replacement service. The rotor’s 69 mm center hole diameter, 12.6 mm bolt hole diameter, and 5-hole layout align with the specified fitment. As part of the DFC GEOSPEC Coated Rotor line, this rotor is positioned for drivers who want a service replacement with a coated-rotor product line designation and a non-directional surface for easier installation orientation. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Replacement Uses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake pulsation caused by rotor wear or uneven surface condition.\u003c\/li\u003e\n\u003cli\u003eReduced braking consistency from a worn rear rotor.\u003c\/li\u003e\n\u003cli\u003eService replacement for a rotor that no longer meets discard thickness.\u003c\/li\u003e\n\u003cli\u003eNoise or vibration related to rotor surface irregularity.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify rear fitment before ordering and confirm the rotor dimensions against the existing part.
