To see and choose from the full list of delivery services, we recommend ordering direct-ship parts on their own.

Direct shipped from our US warehouse

What Is Direct Shipping?

This part ships straight to you from our US warehouse rather than sitting on our shelf in Clyde. You get a wider range and current pricing — the trade-off is that it takes a little longer to arrive than something we stock locally.

  1. You Order

    Check out as normal and you will get an order confirmation straight away.

  2. 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.

  3. It Ships To You

    It flies direct to your door by courier — it does not route through our workshop. You get the tracking number as soon as it leaves.

  4. It Arrives

    If you ordered anything we stock locally, that ships separately from Clyde — so an order can arrive in more than one delivery.

Delivery Time

Our supplier quotes 2–4 weeks from order to delivery.

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.
