SKF 12425 Manual Transmission Seal - Front

SKF Manual Transmission Seal for OE-Style Service

SKF Part Number 12425 is a manual transmission seal built for precise shaft sealing in drivetrain service. It is designed around a 1.250-inch shaft diameter, 1.755-inch outside diameter, and 0.252-inch width to support a proper sealing fit in the intended application.

For Ford Mustang front applications and other listed fitments, this seal helps maintain lubricant retention at the transmission shaft while keeping road contaminants out. SKF 12425 is also listed for Chevrolet Corvette front and Chevrolet Camaro applications, making it a focused replacement for select performance and passenger vehicles.

Detailed Description

SKF has a long history in seal engineering, and Part Number 12425 reflects that focus on material selection and sealing design. This manual transmission seal is manufactured to specific dimensions for the application, helping deliver the correct sealing contact where the shaft passes through the transmission housing. The LongLife sealing surface type is intended to support durable sealing performance in demanding drivetrain environments.

This part cross-references Ford 1R3Z7052AA for the same application. If you are servicing a Ford Mustang front seal, or replacing a seal on a Chevrolet Corvette front or Chevrolet Camaro transmission, SKF 12425 provides a direct-fit service part reference for those listed vehicles.

What It Helps Address

• Transmission fluid seepage at the shaft seal area
• Contamination entering the transmission through a worn seal
• Seal wear from age, heat, and drivetrain movement
• Leak-related drivability concerns tied to low lubricant level
• Service replacement for select Ford Mustang, Chevrolet Corvette, Chevrolet Camaro, and Dodge Challenger applications

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal orientation before installation. Clean the sealing surface and surrounding bore thoroughly, and inspect the shaft for grooves or wear that could affect sealing performance. For best results, install the seal squarely to avoid distortion of the lip or sealing surface.

Quality Assurance

SKF designs and manufactures seals to specific application requirements using premium materials and established sealing engineering practices. Part Number 12425 is built to meet the dimensional and performance needs of the listed manual transmission applications.
