ACT MB2-HDG6 HD Race Sprung 6 Pad Clutch Kit 1991-1999 3000GT VR-4 Stealth TT

Vehicle Fitment

• 1991-1999 Mitsubishi 3000GT VR-4 (3.0L 6G72TT Twin Turbo, AWD)
• 1995-1996 Mitsubishi 3000GT Spyder VR-4 (3.0L 6G72TT Twin Turbo, AWD)
• 1991-1996 Dodge Stealth R/T Turbo (3.0L 6G72TT Twin Turbo, AWD)

Fitment Notes

• This kit is specific to the twin-turbocharged AWD models only - the 3000GT VR-4 and Stealth R/T Turbo. It does not fit the naturally aspirated 3000GT SL, 3000GT base, Stealth R/T non-turbo, or Stealth base, all of which use a different clutch system and disc size.
• This kit must be used with an ACT flywheel. The 6-pad spring-centered race disc requires an ACT flywheel for proper engagement geometry - it is not compatible with the OEM stock flywheel. The flywheel is not included in this kit.
• The 3000GT/Stealth AWD twin-turbo platform uses a pull-type clutch release system. The included throw-out bearing (RB835) is application-specific and must not be substituted with bearings from other platforms.
• No pilot bearing is included or required for this application.
• This kit is recommended for high-horsepower street or race use - it is not a direct drop-in street replacement equivalent to an organic disc kit. The 6-pad sprung ceramic disc will produce more aggressive engagement and increased gear rattle compared to a street disc.

Features

• ACT Heavy Duty pressure plate delivers a 20-50% increase in clamping force over the OEM unit, providing the additional torque capacity required by modified and built 6G72TT engines producing well beyond stock power levels.
• All Heavy Duty diaphragm springs endure ACT's exclusive four-stage heat-treating process, producing a diaphragm that resists deflection and maintains consistent clamping force across the full service life of the clutch.
• Precision cover stampings maintain rigidity and consistent clamp load across all RPM ranges, from idle engagement to full-throttle race launches.
• 6-pad spring-centered ceramic race disc is the preferred configuration for the larger 250mm disc diameter found in the 3000GT/Stealth AWD drivetrain - the additional pad count provides greater heat absorption capacity than a 4-pad design, making it better suited for sustained high-load and high-temperature operation.
• Spring-center hub construction properly damps torsional vibrations for quieter operation and resists failure under harsh race conditions, offering a meaningful durability advantage over rigid (solid) hub disc designs in high-heat environments.
• ACT spring retainers use wraparound spring windows and thicker retainer stampings to provide superior spring support, reduce stress concentrations, and extend disc service life under race loads.
• Premium ceramic friction materials deliver high heat tolerance, excellent friction coefficient, and low wear rates under sustained race-level thermal stress.
• Chrome-moly disc hub is heat-treated for maximum fatigue strength and durability under the high-RPM, high-torque operating conditions of the 6G72TT engine.
• Dynamically computer balanced to within 0.25 oz-in for vibration-free operation across the full RPM range - twice the precision of most OEM production clutches.
• 100% clamp load tested prior to shipment to ensure consistent engagement force in every unit.
• SFI 1.1 certified race disc - legal in all racing organizations that require SFI certification.

Product Description

The ACT MB2-HDG6 is a Heavy Duty / Race Sprung 6 Pad complete clutch kit engineered specifically for the twin-turbocharged AWD drivetrain of the 1991-1999 Mitsubishi 3000GT VR-4, the 1995-1996 3000GT Spyder VR-4, and the 1991-1996 Dodge Stealth R/T Turbo. It pairs ACT's Heavy Duty pressure plate with a 6-pad spring-centered ceramic race disc - the combination best suited to the 250mm clutch diameter and AWD pull-type release system found in this platform, and the disc configuration preferred for applications where sustained high-heat capacity and manageable driveline shock are equally important.

The HD pressure plate increases clamp load 20-50% over OEM through ACT's exclusive diaphragm design and four-stage heat-treating process, providing a firm but manageable pedal feel that remains usable for performance street driving while delivering the torque capacity demanded by built 6G72TT engines. The 6-pad spring-centered disc outperforms both street discs and 4-pad configurations in high-heat sustained-load scenarios - the six ceramic friction pads offer greater total friction surface area for heat absorption, and the spring-center hub dampens torsional shock between engine and drivetrain, reducing the aggressive on/off bite that characterizes rigid-hub discs. The result is a race-capable clutch that is substantially more livable in traffic and on track exit zones than a rigid alternative.

A key installation requirement for this platform: the 6-pad sprung disc requires an ACT flywheel for correct engagement geometry and clutch step height - this kit is not compatible with the OEM stock flywheel and the ACT flywheel must be sourced separately. No pilot bearing is needed. The included throw-out bearing (RB835) is specific to the 3000GT/Stealth AWD pull-type clutch release system. A few hard clutch slips are sufficient to lap in the ceramic friction surfaces before full race use.
