What Is Direct Shipping?
This part ships to you from our warehouse inside the United States - no customs, no import duty, no brokerage. It travels separately from anything we send from our workshop in Sydney, Australia.

-
We Place The Order
We order the part the same business day and it is picked from our US warehouse, brand new and factory sealed.
-
It Ships To You
It goes to your door by ground courier, straight from the warehouse - it never routes through our workshop. You get the tracking number as soon as it leaves.
-
It Arrives
If you also ordered something we ship from our workshop in Sydney, Australia, that travels separately - so an order can arrive in more than one delivery.
Delivery Time
It ships by ground courier from the nearest US warehouse, and your courier options are shown at checkout. Parts that are out of stock take longer - the page tells you when that applies.
No Import Fees
This part ships to you from inside the United States, so there is no customs clearance, no import duty and no brokerage fee.
Any applicable sales tax is calculated at checkout.
Product details
The crankshaft from Brian Crower's 3.8 V6 stroker kit, sold on its own. 4340 billet steel, 93mm stroke against the stock 87mm, stress relieved, shot peened, magnaflux inspected and nitrided, with profiled counterweights.
- Fully Balanced - balanced by Brian Crower.
- Unbalanced - your machinist balances it to your rods and pistons.
It keeps the factory 5.886in rod length, so it needs pistons with a shorter compression height, and rods built for the load. On its own it suits a builder who already has rods and pistons; otherwise the complete kit is the easier buy.
Fits the Genesis Coupe 3.8 V6, 2010-2016, MPI and GDI engines. Brian Crower lists it as G6DA. Not the 2.0T, and not catalogued for the front-drive 3.8 in the Azera or Veracruz.
