• 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 plate.
