DESCRIPTION AND SPECIFICATIONS

HKS Step 3 Full Stroker Kit for R32 / R33 / R34 Nissan Skyline GT-R

For drivers who just need “more power & more torque”. HKS has designed a series of capacity upgrade kits to suit each engines characteristics. Increased displacement offers more torque at lower engine speeds and by using the highest quality materials, the durability required for high levels of tuning is achieved. Nickel coated pistons which have strong anti-knocking properties combined with fully counterweighted crankshafts and high strength connecting rods (rods optional in some kits) combine to extract maximum performance from the turbocharger and increase torque.

Features

High strength kit designed for high power.

Piston Kit

  • Piston Weight : 324kg
  • Made of highly heat-resistant & durable A2618 alloy.
  • Machining 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 & shorter in length.
  • The shortened piston pin makes pin boss lighter.

Crankshaft : 77.7mm Stroke

  • A thinner, harder, wear resistant & high quality full counter crankshaft rated for 1200hp.
  • Material is high-end racing grade nitriding steel / EN40B (BS722M24).
  • The same ion plasma nitriding treatment used in high quality racing cranks is applied for 50 hours to increase the surface strength & toughness required for high cycle performance crankshafts.
  • HKS’ craftsmen’s uncompromising approach to design led to create a unique shape w/ high balance ratio & lower moment of inertia.
  • Strongest crank with the ultimate material and ion plasma treatment.

Connecting Rods

  • H-Beam machined by nicked chromium steel (SNCM)
  • Specially designed to fit thinner & shorter lightweight D22 pins.
  • Increase fatigue strength by WPC treatment.

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions.
