About this part

Product Details

If you're pushing your 2001-2004 Ford Mustang GT or Cobra/Mach 1 beyond its stock clutch's limits, a Stage 4 clutch kit like this one from SPEC is a solid choice. This kit is built to handle significantly more power and torque than the original equipment, making it suitable for modified engines or demanding driving styles. It's designed to provide a firm engagement and reliable performance when you need it most.

This SPEC Stage 4 clutch kit features a high-performance friction disc and a robust pressure plate, engineered to manage up to an estimated 600 lb-ft of torque. The disc uses a multi-plate design with a sprung hub to help absorb shock and reduce drivetrain stress, while the pressure plate offers increased clamping force. This combination ensures that power is transferred efficiently to the wheels, even under heavy load. SPEC is known for well-built drivetrain components, and this kit reflects that reputation for durability and performance.

When installing a clutch kit of this caliber, it's a good idea to inspect your flywheel for wear and resurface or replace it if necessary. This kit is designed as a direct replacement for the factory clutch assembly, simplifying the installation process for mechanics familiar with Mustang clutch jobs.
