They are comp CT2 4747 billet triple ball bearing. Just call the number on their main website to inquire. They have great customer service.

Here it is dyno tuned. 472whp & 421ft-lb @9psi

The combination of cold weather and worn out Michelin PSS gave me a hard time with traction on the rollers. 4th gear would not hook. I ended up having 2 of the guys sit on the trunk to give it traction.

My impression on the result is exactly how I intended for the kit to deliver. Instant throttle response, high mid range torque with a feasible powerband. The .64 AR housings are showing their limitation as torque is ramping down on top end, and they are not meant to make peak power. I did wanted to increase boost a bit and hit 500whp but I did not have any boost controller setup. Overall the graph is smooth and shows no sign of hiccup.
