Grip Racing Twin Disc and Flywheel Clutch System – Upgraded High-Copper Organic
The Grip Racing Street Twin-Disc Clutch and Flywheel System is engineered for Dodge Challenger applications, originally designed around a twin-disc clutch architecture. Grip Racing enhances that proven configuration with upgraded friction materials, stronger contact surfaces, and a durable ductile-iron flywheel.
Two full-face organic discs feature increased copper content for improved heat transfer, fade resistance, and service life. The additional friction area of the twin-disc design distributes load and heat across multiple surfaces, providing confident power transfer without the abrupt behavior of a small-diameter racing clutch.
The pressure-plate assembly features a ductile-iron friction surface for improved strength, thermal stability, and resistance to distortion. A matching Grip Racing ductile-iron flywheel provides the rotational mass needed for controlled takeoffs, stable low-speed behavior, and smooth operation in traffic.
The result is a refined street-performance system: strong enough to support spirited driving, yet progressive and manageable enough for regular use.
Durability:
- Upgraded high-copper organic friction material for improved heat transfer and fade resistance
- Two full-face discs distribute load and heat across multiple friction surfaces
- Ductile-iron pressure-plate friction surface for increased strength and thermal stability
- Sprung disc hubs help absorb torsional vibration and drivetrain shock
- Nodular ductile-iron flywheel for dependable structural integrity
- Heat-treated diaphragm spring maintains consistent clamping force
- Hardened flywheel ring gear supports reliable starter engagement
Performance:
- Pedal Feel: Smooth and predictable with a confident performance-oriented feel
- Engagement: Progressive and controllable with a strong, smooth bite
- Response: Direct, deliberate power transfer without aggressive race-clutch behavior
- Heat Management: High-copper friction material and ductile-iron contact surfaces help manage repeated heat cycles
- Drivability: Comfortable for commuting, traffic, inclines, and spirited street use
- Noise: Designed for refined operation with minimal additional clutch noise, low-to-none gear rattle at idle or low rpm's
- Recommended Use: Daily driving, spirited street use, mildly modified Challengers, canyon driving, and occasional light track use
What's Included in the Complete Grip Racing Twin Disc and Flywheel Clutch System:
- 1x Grip Racing Ductile-Iron Flywheel
- 1x Grip Racing Street Twin-Disc Pressure-Plate Preassemble
- 1x Steel Pressure-Plate Floater
- 2x High-Copper Full-Face Organic Sprung Clutch Discs (spline info)
- 1x Release Bearing
- 1x Pilot Bearing or Bushing (if applicable)
- 1x Alignment Tool
Weight: 42 lbs
Ring-Gear Tooth Count: 23
Ring Gear: Induction-hardened
Torque Capacity: 700+ lbft
Recommended Break-In Period: 500 miles
Note: This Challenger twin-disc system includes one independent flywheel-side disc and one disc contained inside the preassembled pressure-plate unit. Do not disassemble the pressure-plate unit or remove its internal components. Doing so may cause improper clutch release, slipping, chatter, premature wear, or component damage.
The flywheel, clutch discs, floater plate, pressure plate, and release components are engineered to function as one matched assembly. Individual components may differ visually or dimensionally from the removed parts while maintaining the correct assembled operating geometry.
Do not mix, reuse, or substitute components from another clutch or flywheel system. Professional installation is strongly recommended.
Grip Racing OE-HD Ductile-Iron Flywheel
Product Overview:
The Grip Racing OE-HD Ductile-Iron Flywheel is designed for drivers who want dependable strength, smooth engagement, and predictable everyday drivability. Its one-piece nodular ductile-iron construction provides a durable foundation for the clutch while retaining the rotational mass needed for controlled takeoffs, stable idle quality, and comfortable low-speed operation. Unlike a lightweight racing flywheel, the OE-HD is engineered around balance and usability. It stores more rotational energy, helping the engine maintain momentum as the clutch engages. This makes pulling away from a stop easier and reduces the need for additional throttle especially in traffic, on inclines, or during frequent starts.
For applicable dual-mass or modular-clutch conversions, the solid OE-HD flywheel creates a simpler, serviceable clutch arrangement without unnecessary complexity.
Flywheel Benefits:
High-strength nodular ductile-iron construction
Greater resistance to cracking and deformation than conventional gray cast iron
Excellent thermal stability under repeated street-driving heat cycles
One-piece construction for consistent heat transfer and structural integrity
Hardened ring gear for dependable starter engagement
Resurfaceable friction surface for continued serviceability
Performance:
- Acceleration: Smooth, predictable engine behavior with OE-like rotational inertia
- Engagement: Progressive takeoff with excellent low-speed control
- Drivability: Well-suited for traffic, hills, commuting, and regular street use
- Noise: Designed for refined street operation; low drivetrain noise may occur in solid-flywheel conversions
- Recommended Use: Daily driving, stock or mildly modified vehicles, spirited street driving, and light-duty performance applications

Frequently Asked Questions
Are ACT clutches balanced?
Yes! All ACT clutch assemblies are computer spin balanced to within .25 oz-in to guarantee help smooth operation across the entire RPM range. For comparison, stock production clutches are typically balanced to within .50 oz-in. Lower is definitely better!
Will an ACT clutch increase pedal effort?
ACT pressure plates are specifically designed to handle high torque applications. With ACT's durable design, expect an increase in pedal effort between 15-40% (Heavy Duty) and 50-80% (Xtreme), depending on the application. Clutches developed with less pedal effort often result in a lack of longevity, torque capacity and/or engagement quality.
Do ACT clutches require a break-in period?
For organic street discs, we recommend breaking in the clutch for 300-500 miles with mild engagement, such as stop-and-go city driving prior to racing or spirited driving. ACT race discs usually only require a few hard slips to lap in the surfaces prior to normal driving or racing. Do not overheat the clutch during the break-in period, as this can result in friction surfaces fusing together, hot spots, and friction surface glazing.
Are ACT clutches repairable or rebuildable?
In some situations, rebuilds or repairs may be possible (see warranty), after inspection of the clutch assembly. Please contact our technical department for further information. Because of special modifications, we do not recommend servicing by a general clutch rebuilder.
How much does an ACT clutch weigh?
The weight of the ACT clutch assembly will usually be the same as a stock OEM clutch assembly.
