They are working to get figures for motor movement compared to stock. They did try and keep it as minimal as possible and sit the engine as low as possible in the cross member.
I did get some numbers for ride height though. The system is designed to lay out on a 30" tall tire, for both front and rear.
Ride height is about 5.5-6" with a 30" tall tire. If running a 28" tall, then this will drop to appx. 4.5-5".
Also a picture of a truck running front and rear kits that will be at SEMA this year, built by Justin Carrillo.
