The rotor uses a directional surface pattern and vented construction, with an 18 mm nominal thickness, 16 mm discard thickness, 324 mm outside diameter, and 56 mm overall height. The black zinc hat finish and rust-resistant coating help protect exposed surfaces from corrosion, while the 72 mm center hole diameter and 13 mm stud\/lug hole diameter support proper hub alignment. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake pulsation from worn or uneven rotor surfaces.\u003c\/li\u003e\n\u003cli\u003eReduced braking consistency caused by heat buildup.\u003c\/li\u003e\n\u003cli\u003eCorrosion on exposed rotor surfaces and hat area.\u003c\/li\u003e\n\u003cli\u003eNoise or vibration related to rotor wear.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify rear left position fitment before installation and confirm rotor dimensions against the existing part.
