I found some more info here:
This unit can be setup to add lift in the front for up to 2-inches of leveling. This is done by relocating the spring perch. Bilstein 5100 series offroad Racing Shock.
5100's are specifically engineered for offroad and lifted vehicles.
14mm Hardened Chromed piston rod
One piece alloy rod guide & seal system
46mm piston with self-adjusting digressive valving
One piece seamless monotube shock body
Patented nitrogen chamber and floating dividing piston
360psi gas pressure
Depending on the vehicle chassis and race set-up, some modifications may be needed to adapt these to your suspension. See your offroad mechanic or lift kit manufacturer for specs.
I wonder how well these would work with my modified OME coils? Adjusted all the way down they still provide a 3/4" lift.
Does anyone know what the extended length is on the OME struts?
