Product Details

Power Stop drilled and slotted rotors are engineered as a bolt-on brake upgrade for vehicles that need improved cooling and a cleaner rotor surface under repeated braking. The cross-drilled pattern helps move heat away from the braking surface, while the rounded slots sweep away gases, dust, and moisture to support stable pad contact. AR8309XPR also uses a silver zinc dichromate finish to help slow surface corrosion on exposed rotor areas.

This rotor set cross-references DENSO Auto Parts 5311 and Monroe Shocks & Struts 172286 for the same application. It is a direct replacement choice for front brake service on Chrysler New Yorker, Chrysler Newport, Dodge Charger, Dodge Monaco, and Dodge Magnum models listed below.

What It Helps Address

• Brake fade during repeated stops
• Heat buildup in front brake service
• Dust and moisture film on the rotor surface
• Surface rust on exposed rotor areas
• Uneven friction contact caused by contaminated rotor faces
