Description

If you're running a 2003-2004 Mustang Cobra with IRS, the pinion flange is a critical wear item that directly impacts driveshaft security and rear axle performance. A worn or damaged flange introduces play in the drivetrain, reducing power transfer efficiency and risking catastrophic failure under hard acceleration. Ford Performance's M-4851-B delivers OEM-spec durability with domestic manufacturing quality—the direct replacement your Cobra needs for reliable power delivery.
