ACT T3SS-F17 Mod-Twin 10.5 XX Sprung Street Clutch Kit for 24-26 Ford Mustang GT

Vehicle Fitment

• 2024-2026 Ford Mustang GT - 5.0L V8 (S650 chassis, manual transmission)
• 2024-2026 Ford Mustang GT Premium - 5.0L V8 (S650 chassis, manual transmission)

Fitment Notes

• Manual transmission applications only - not compatible with automatic or dual-clutch variants
• Flywheel IS included - complete twin disc kit with CNC-machined and dynamically balanced flywheel; no separate flywheel purchase required
• Sprung Mono-Drive hub - retains torsional damping for street use; more driveable than rigid hub race variants
• Maxx Xtreme (T3) pressure plate - highest clamping load in the Mod-Twin street lineup; expect pedal effort just above stock per ACT's press release
• Recommended for street, street/strip, drag, road course, and rally applications - handles all types of power adders including superchargers, turbos, and nitrous
• Street disc requires a 300-500 mile break-in period with mild engagement before spirited or track use
• Fully rebuildable - replacement discs and most components can be ordered separately
• SFI certified

Features

• Mod-Twin 10.5" dual-disc design - doubles the organic friction surfaces versus a single-disc kit for superior heat capacity, wear life, and torque capacity on heavily modified Mustang GT builds
• ACT Maxx Xtreme pressure plate with forged aluminum cover - ACT's highest-clamping diaphragm design in the Mod-Twin street lineup, delivering maximum torque holding power at 1,169 ft-lbs. with just-above-stock pedal effort
• Four-stage heat-treated diaphragm springs - ensure consistent clamping force and long-term durability under extreme street and competition loads
• Sprung Mono-Drive hub assembly - torsional damper spring hub reduces drivetrain shock and transmission gear noise for acceptable street manners despite the extreme torque capacity
• Steel-backed organic friction plates - deliver stable friction coefficient, good heat capacity, and long clutch life with smoother street engagement than ceramic race discs
• Positive Lift Floater System - proprietary floater design eliminates rattle and post wear common to conventional twin disc systems for quiet disengagement
• Patented Monoloc Collar - self-adjusts for disc wear over time to maintain consistent pedal feel and ensure equal, simultaneous disengagement of both discs
• CNC-machined and dynamically balanced flywheel - included with the kit; approximately 18% lighter than the OEM 215mm/60 lb. assembly for sharper throttle response
• Computer spin balanced to within .25 oz-in - tighter than OEM production tolerance of .50 oz-in
• 100% clamp load tested - every pressure plate individually verified before shipment
• 93% torque capacity over OEM - rated at 1,169 ft-lbs. at the crank

Product Description

The ACT T3SS-F17 is a Mod-Twin 10.5 Maxx Xtreme Sprung Street twin disc clutch kit for the 2024-2026 Ford Mustang GT (S650) with the 5.0L Coyote V8 and manual transmission. Sitting at the top of ACT's street-oriented Mod-Twin lineup for the S650 platform, the T3SS-F17 is rated at 1,169 ft-lbs. of torque at the crank - a 93% increase over OEM - and is designed for serious high-power builds running aggressive power adders such as centrifugal or positive displacement superchargers, large turbochargers, or nitrous oxide where the T2 (Xtreme) variant's capacity may not be sufficient.

The Maxx Xtreme pressure plate delivers the maximum clamping force in ACT's Mod-Twin street lineup within a forged aluminum cover, yet retains a just-above-stock pedal feel owing to ACT's advanced diaphragm geometry - a meaningful advantage over high-clamp single-disc setups. The sprung Mono-Drive hub assembly maintains torsional damping for acceptable street drivability, reducing shock loads into the driveline and minimizing transmission gear noise compared to rigid hub alternatives. ACT's patented Monoloc Collar adjusts for disc wear over time and ensures simultaneous release of both discs for consistent engagement quality. The included CNC flywheel saves roughly 18% in rotating mass versus the OEM assembly, sharpening throttle response. The T3SS-F17 is SFI certified, fully rebuildable with individually-orderable components, and requires the standard 300-500 mile street break-in before aggressive use.
