The slotted X drilled surface supports more consistent pad contact by helping keep the rotor face cleaner, while the vented design assists with heat management during repeated stops. AR8270XPR is a fitment-based replacement for the rear axle on the Buick Rendezvous, Pontiac Aztek, Oldsmobile Silhouette, and Pontiac Montana listed in the application data.\u003c\/p\u003e\u003cp\u003eThis part cross-references Centric Parts 120.66048 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake fade during repeated stops or higher-temperature driving\u003c\/li\u003e\n\u003cli\u003eRotor surface rust and corrosion exposure\u003c\/li\u003e\n\u003cli\u003eDust buildup on the braking surface\u003c\/li\u003e\n\u003cli\u003eMoisture-related friction inconsistency\u003c\/li\u003e\n\u003cli\u003eUneven pad contact caused by a worn or damaged rear rotor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eInstall on the rear position only for the listed vehicles. Verify rotor dimensions before installation, including 11.40 in. outside diameter, 1.80 in. overall height, and 9.00 mm nominal thickness. Confirm the 5-lug, 115.00 mm bolt circle pattern matches the vehicle hub before assembly.
