SPEC Stage 2+ Clutch Kit for 2011-2014 Ford Mustang GT & Boss 302 (5.0L) - 9-Bolt Cover (SF503H-9)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2011-2014 Ford Mustang GT and 2012-2013 Ford Mustang Boss 302 (5.0L).
The SPEC Stage 2+ Clutch Kit is a high-performance upgrade designed for the 5.0L Coyote and Road Runner platforms. This kit features a hybrid friction surface that bridges the gap between pure streetability and track-ready performance. By utilizing a multi-segmented Kevlar disc on one side and a carbon-graphite semi-metallic material on the other, the Stage 2+ offers a significant increase in torque capacity and heat management without the harsh engagement typical of a full metallic race clutch.
The 9-bolt cover design ensures a precise fit to the factory-style flywheel, providing consistent pressure plate loading for reliable power transfer under load. This kit is ideal for modified naturally aspirated engines or street-driven cars with light forced induction.
- Manufacturer Part Number: SF503H-9
- Friction Material: Hybrid Kevlar and Carbon-Graphite
- Pressure Plate: High-clamp 9-bolt cover design
- Fitment: 2011-2014 Ford Mustang 5.0L applications
- Included: Pressure plate, friction disc, and necessary alignment tools
