You can always look for shocks spec'd for a 4" to 6" lift and build the shock mounts to suit the shock travel. You're not going to have tons of suspension travel with that setup, and it's best to limit uptravel with the correct length bumpstop to lengthen the life of your springs. Repeated over-compressing of springs will shorten their life significantly.
I run Bilstien's, 14" on the front and 11" on the rear, SOA with RE 1.5" springs.
