I have a 2004 Nissan Titan RWD and I need to replace the front struts and rear and shocks. I found a complete front strut assemblies for 4WD and RWD that are fairly cheap for the set. I however have a RWD vehicle. Is there any benefit and will they fit if so to use the 4WD over the RWD set? Both sets are the same price. Sets include Front struts fully assembled and rear shocks.
