The most durable stroker kit with improved response for serious customers

Features:

• Piston Kit
  • Piston Weight - 324g
  • Made of highly heat-resistant & durable A2628 alloy
  • Machined to reduce excess thickness in 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 pins 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 pis boss lighter
• Crankshaft
  • Stroke - 77.7mm
  • 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 the high-quality racing cranks is applied for 50 hours to increase the surface strength and toughtness required of high-cycle performance crankshafts
  • HKS craftsmen's uncompromising approach to design led to create a unique shape with high balance ratio and lower moment of inertia
• Connecting Rods
  • H-Beam machined by nichel chromium steel (SNCM)
  • Specially designed to fit thinner and shorter lightweight D22 pins
  • Increase fatigue strength by WPC treatment

Fits:

• Nissan Skyline GT-R 1989-2002 (RB26DETT)

Notes:

• Boring Honing is required.
• Full Flow is not required.
