About this part

Product Details

The SPEC Stage 4 clutch kit for your 2011-2014 Ford Mustang 3.7L uses a sprung, multi-plate design. This setup is built to handle significantly more torque than the stock clutch, making it a solid option if you've added performance modifications or plan to. The sprung hub helps absorb some of the shock and vibration that can come with a higher-performance clutch, aiming for a more manageable feel on the street.

This kit is designed for serious performance, featuring a high-performance friction material that offers a strong engagement. Because it's a multi-plate design, it spreads the load across more surface area, which helps with heat dissipation and overall durability under demanding use. Keep in mind that a clutch this capable often requires a specific pilot bearing and alignment tool for proper installation, and it's crucial to follow the manufacturer's instructions closely. Remember, this kit requires the SPEC SF37A flywheel to complete the installation.
