Its solid rotor design, 271 mm outside diameter, and 43.3 mm overall height align with the specified vehicle requirements, while the drilled and slotted surface supports more even pad interaction under braking. The zinc silver hat finish and rust-resistant coating add corrosion protection where exposed metal is a concern. This part number, 631-67075L, is a direct-fit style replacement for the confirmed applications shown in the fitment data.\u003c\/p\u003e\u003cp\u003eThis part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake pulsation caused by worn or uneven rotor surfaces.\u003c\/li\u003e\n\u003cli\u003eReduced braking consistency from heat buildup.\u003c\/li\u003e\n\u003cli\u003eCorrosion on exposed rotor surfaces and hat areas.\u003c\/li\u003e\n\u003cli\u003eNoise or uneven pad contact related to rotor wear.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify rotor dimensions, bolt circle, center hole diameter, and directional orientation before installation.
