i have rancho rs5000 shocks on the front with what looks like a rancho rs 5000 stabolizer shock in the front also. i bought the jeep with them on there. are these decent shocks and how can i tell if i need to replace them? as far as the rear i cant tell what kinda shocks are back there, i need shocks for high way driving as this is my daily driver. any advice would be appreciated.
