Full billet 4340 Nitrided and Balanced Crankshaft
Note: The standard RB26 capacity is 2568cc
Using the 77.7mm stroker crank, std length conrods and custom pistons, the displacement is increased as follows:
- 86.5mm bore and the 77.7mm stroker crank = 2740cc / 172cc increase
- 87mm bore and the 77.7mm stroker crank = 2771cc / 203cc increase
With the increased cubic capacity from the 77.7mm stroker crank, big increases in torque and low to mid range power are achievable. Boost will come on earlier in the rev range and peak power will increase.
CP pistons come with rings, pins and locks. The gudgeon pins are upgraded to 9310 hardened alloy steel with 4.5mm wall thickness.
Note: Clearancing of the cylinder block is sometimes required.

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.
