4" Suspension lift, but it's maxed out IMO. I've got only a couple inches of droop in the front and am using ALL the travel in the struts ( OME with a 1.5" spacer ) + limit straps to prevent over extension, with modified stock control arms, 16" FOA 550 lb coils with a bit of trimimng to fit the coil pocket in the control arm which has be cut and re-angled.. In the rear FOA 16" coils, Doetch Tech shocks with modified upper and lower mounts. Both ends have had the Hagon trreatment. Rides real nice though and handles terrian very well.
Can't wait to see how you engine build works out.
