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.
-
You Order
Check out as normal and you will get an order confirmation straight away.
-
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 flies direct to your door by courier — it does not route through our workshop. You get the tracking number as soon as it leaves.
-
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. Most orders land inside that window, though customs clearance can occasionally add a few days.
Duties & GST Are Included
The price shown includes GST and any import duties. There is nothing extra to pay when your order arrives.
You should never receive a bill from customs or the courier. If you do, send it to us and we will pay it.
Product details
JE's FSR forged piston for the G4KF Theta 2.0T. 2618 aluminium, forged and machined in the USA, with a coated skirt, an accumulator groove between the top two rings, and JE Pro Seal rings, 22mm (0.866in) pins and locks included.
- 9.0:1 compression, dished: -5.5cc (86.00mm), -5.9cc (86.25mm), -6.2cc (86.50mm)
- 1.181in (30mm) compression height, for the factory 86mm stroke and rods
- Standard bore or oversize: the block is bored and honed to suit. The 86.25mm set carries a thicker-wall pin
These are for a built engine. On a near-stock car they gain nothing; they earn their place when boost and power go well past factory. The single is a standard-bore spare.
Fits the Genesis Coupe 2.0T (G4KF), 2010-2014. Not the 3.8 V6. The 2.0 T-GDi (G4KH) in the i30 N, i30 Sedan N, Kona N and Veloster N shares the G4KF's internals, so the set suits those engines too.
