Component Features

Flywheel

• Weight: only 3.50 kg
• Material: Forged CrMo steel, nitriding heat-treated
• Hardness: HRC 58–62 → over twice as hard as standard flywheels
  → Prevents wear on starter ring gear in high-compression engines
• Longevity: High surface hardness = extended service life & reliability

Clutch Cover

• Material: Forged 6061-T6 aluminum, hard anodized
• Construction: Steel-riveted legs for near-lifetime durability. Hardened steel thrust buttons/rivets offer a smooth and durable surface for the clutch cover legs, pressure, and floater plates.
• The tightening torque for the clutch plate screws is 4.5Nm, both for single-disc and twin-disc clutches.

Top/Pressure & Floating Plates

• Material: Forged chromoly steel, cryogenically treated (in some applications)

Clutch Disc

• Material: Sintered friction with multiple design options
• Standard version: Three large pads
• Customization: Available on request (e.g. custom spline)

Stick-Up Adapter

• Material: Induction-hardened steel (50–55 HRC)
  → Minimal wear and long-lasting performance

Key Features & Benefits

✔ Rated for 400+ hp / 450+ Nm in single-disc configuration, depending on clutch setup (diaphragm spring pressure and clutch disc friction material).
