How much up travel do you have in the rear. I just moved the shock mounts up and am looking for new shocks (5125 or 5150 bilsteins). My only concern is the 10'' shock will only give me about an inch and a half up travel with plenty down travel. If I go with an 8'' shock I'll gain some up travel but lose down travel. Any insight? O'yeah I have the 5.5'' Re springs/lift
