Description
Competition-Level Clutches. Maximize your track-only Mustang’s performance with the Spec Stage 4 Clutch. Spec Stage 4 Clutches are engineered to give you the clutch response necessary for racing consistently. With three different clutch wheel configurations available, you’re able to fine-tune your Mustang just the way you want.
Superior Torque Handling. Spec Stage 4 Clutches are built to handle up to 755 ft./lbs. of torque, making this clutch the best choice for heavily modified Mustangs. Stage 4 Clutches will give you unparalleled clutch performance on the racetrack.
3 Different Puck Configurations. Spec Stage 4 Clutch Wheels are available in 3-, 4-, or 6-puck configurations letting you fine-tune clutch engagement. The 3-puck wheel is your best choice for saving weight; for smoother clutch engagement that’s even drivable on the street (but not street friendly), the 6-puck wheel is your best option. The 4-puck configuration gives the best balance between performance and smoother clutch engagement.
SFI Approved for Motor Sports. Spec Stage 4 Clutches are SFI approved, making it applicable for racing. SFI approval also means your Spec Stage 4 Clutch has been tested to be able to take the rigors of competitive driving.
Constructed for The Track. Spec Stage 4 Clutches’ 8-rivet, solid hub clutch aggressively engages and disengages the flywheel, for race-level performance. The carbon-graphite friction material is designed to handle the extreme temperatures typical in competitive driving, while preventing clutch failure. The high clamp pressure plate provides the right amount of aggressive and precise engagement.
Backed by a 120-Day Warranty. The Spec Stage 4 Clutch is backed by a 120-day warranty against defects due to materials and workmanship. Please visit the Spec website for more details.
