Ideal Upgrade for the Track. Designed with performance in mind, the Spec Stage 4 Clutch is the perfect upgrade for any serious racer. Spec’s Clutch is perfect for heavily modified engines being used in driving where instantaneous engagement and light weight are beneficial. Although not completely street friendly due to harsh engagement, you can expect the Stage 4 Clutch to perform in the race track.
Optimum Control. If your Mustang is set up for race duty with a little bit of street driving, the Spec Clutch is just what you need. This Stage 4 Clutch will easily transfer up to 562 ft-lb of torque to your drivetrain. So you can be confident this clutch will stand up to your high torque V6 Mustang.
Solid Constructions. Spec’s carbon-graphite friction Stage 4 Clutch is a solid hub version of their Stage 3 kit featuring a heat treated- 8-rivet hub assembly that offers strength and durability. It is available in 3, 4, or 6 puck configuration. The 3 puck is the lightest option, while the 6 puck is for the smoothest engagement. Use the 4 puck for a good compromise of both, and the 6 puck for street driving.
SFI Approved. Each SPEC Clutch has been SFI 1.1-certified for high-performance driving and off-road applications, including this Spec Clutch. You can trust Spec for the best in value, performance, and safety for clutches.
Limited Warranty. S.P.E.C., Inc offers a limited warranty for all products to be free of defects in materials and workmanship for normal use and service up to 120 days after retail purchase. Check the Spec website for terms and conditions.
Application. The Spec Stage 4 is designed to fit on all 3.8L Wrangler JK models manufactured from production dates 05/2007 to 02/2009.
