Spool RB30 Full Counter weight 4340 Billet Crankshaft with a 94mm stroke.
RB34 Stroker Crank to suit Nissan Skyline RB30 and Holden RB30 VL Commodore engines
We have Pistons available to suit both Twin Cam and SOHC cylinder heads.
This is a true billet crankshaft machined from Billet 4340 core stock (not a cast forging blank that is final machined).
Each crank is machined from core stock 4340 on a CNC machine, then Nitrided and final ground.
We have customers making over 1000 hp with our billet crankshafts!
As you can see from the table below. The RB34 has a very similar rod/stroke ratio as the Nissan CA18 and Toyota 2JZ both of which love to rev and have been around a long long time.

With the increased cubic capacity from the 94mm stroker crank, increases of up to 50% in torque and low to mid range power are achievable. Boost will come on earlier in the rev range and peak power will increase.

Delivery & Freight
We are an Australian-based company that ships items nationally and internationally, usually within 48 hours of receiving your order. High-value items shipped internationally are sent via DHL Express, while lower-value items are sent via Australia Post Express unless otherwise instructed.
You can calculate shipping rates inside the shopping cart. After adding all the products you would like, navigate to the cart and click the ESTIMATE SHIPPING & TAX link. For Australia, you need to select from ALL dropdowns (Country, State, Suburb, and Postcode) for the quote system to work. (There may be a small delay as it searches.) For international orders, you only need to select the Country to get a quote, but more details are required at checkout to complete the order.
If you have issues calculating freight, please get in touch. The most common reason for issues is that the postcode does not match the suburb, or the suburb is spelled differently from what the carriers have.
