Capacity Upgrade Kit by HKS

The most durable stroker kit with an improved response for serious customers, capable of handling up to 1200hp.

Features

  • Piston Kit:
  • Made of highly heat resistant and durable A2628 alloy
  • Machined to reduce excess thickness parts to achieve ultra-lightweight
  • Adapting truss structure for improved structural rigidity
  • Double-layer molybdenum coating to reduce friction and improve initial fit-in
  • Using D22 piston pin instead of D21 to increase flexural rigidity yet achieving the same weight by making the pin itself thinner and shorter in length
  • The shortened piston pin makes the pin boss lighter
  • Crankshaft:
  • A thinner, harder, wear-resistant high-quality full counter crankshaft for 1200hp
  • Material is high-end racing-grade nitriding steel/EN40B (BS722M24) for serious customers
  • The same ion plasma nitriding treatment used in high-quality racing cranks is applied for 50 hours to increase the surface strength and toughness required of high cycle performance crankshafts
  • HKS craftsmen's uncompromising approach to design led to creating a unique shape with a high balance ratio and lower moment of inertia
  • Connecting Rods:
  • H-beam machined by nickel-chromium steel
  • Specially designed to fit thinner and shorter lightweight D22 pins
  • Increase fatigue strength by WPC treatment

Benefits

  • Improved Reliability
