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.


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 Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.
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 here.
We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at with any inquiries.
