Advice on suspension upgrades??

I have a 05 access cab, it has the oem leveling kit and slightly oversized tires, other than that it's stock. It's my daily driver so I don't want to go too crazy with a lift but I drive washboard/rough gravel roads to and from work every day. Any suggestions on smoothing out the ride, with out taking the ability to run down the hwy at 75-80 mph.I tend to be a pretty aggressive driver, so idling down the road at 25 isn't exactly what I have In mind. Right now I am just trying to gather information so anything helps.

THANKS

 

What is the oem leveling kit? Was it a dealer add on?

To upgrade and give a little more lift all around I'd suggest some OME springs along with Dakar leaf springs.

 

I bought the truck used, the dealer I got it from said it was a oem option that had been put on, basically a 1-1 1/4 inch spacer block on top of the strut.

 

I consider myself in the same position position as you, lordofire77. would a 2.5" leveling kit in the front along with an add-a-leaf be appropriate? I am looking to get a tad more height without looking too aggressive, maintain a smooth ride at high speeds while adding some stiffness for mud season and logging roads.
