 Component Features

 Flywheel

• Weight: only 3.0 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 floating plates.

Top/Pressure Plate

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

Sintered Clutch Discs — Ø184 mm (7.25")

• Material: Proprietary blend of sintered metal compounds, engineered with precise manufacturing tolerances
• Standard version design: Three large friction pads for optimal engagement and reliability.
• Standard Spline: 15/16" (23.8 mm x 21T) for C5... gearboxes
• Hub: Machined from forged chromoly steel and induction hardened for maximum strength and wear resistance
• Customization: Available on request (e.g. custom spline)

Clutch release bearing + specific  support
