DESCRIPTION (STAGE 5 CLUTCH + 10LBS LIGHTWEIGHT FLYWHEEL)
This listing is for a brand new XTD Stage 5 clutch kit with 10LBS lightweight flywheel. Built for serious enthusiasts running turbo / supercharger / nitrous or heavy engine modifications, this combo is designed to handle hard launches and repeated heat cycles while improving throttle response.
STAGE 5 CERAMIC DISC – STRONG BITE / HIGH HEAT RESISTANCE
• Ceramic friction provides strong bite and excellent heat resistance.
• Race-style design helps the clutch lock up fast for quick power transfer.
• Designed for track/drag and aggressive street builds where holding power matters.
XXTREME PRESSURE PLATE – 2300LBS CLAMPING FORCE (APPROX.)
Heavy-duty ductile iron construction with heat-treated components for strength under load. Higher clamp force improves slip resistance under boost and during repeated launches.
10LBS LIGHTWEIGHT FLYWHEEL – BENEFITS (WHY IT MATTERS)
A lightweight flywheel reduces rotating mass, allowing your engine to rev more freely. This results in quicker throttle response, faster RPM changes, and a more “connected” feel during spirited driving.
KEY ADVANTAGES
Faster engine response – reduced inertia helps the engine rev up and down quicker
Improved acceleration feel – quicker drivetrain reaction during throttle blips and shifts
Better shift recovery – quicker RPM drop can help performance shifting (driver/setup dependent)
Less rotational mass – reduces power loss to spinning weight for more efficient power transfer
Cooling-focused design – airflow features help manage clutch temperatures under load
Heat-treated Chrome-Moly steel – strong and durable for demanding applications
Precision-machined ring gear – reliable starter engagement and long service life
High RPM capability – engineered for performance environments
PERFECT MATCH WITH STAGE 5
Pairing a lightweight flywheel with a Stage 5 clutch helps the car feel more responsive and “race-ready,” especially for aggressive driving, track days, and hard street use.
BREAK-IN / IMPORTANT INSTALL NOTES
500 miles break-in recommended (avoid hard launches during break-in).
• Professional installation recommended.
• Performance ratings vary by vehicle condition, tune, driving style, and installation quality.
