Konis and Ground Controls would be a good choice.

Just beware that on stock valved OTS Konis, if you go above 350lb springs, the ride quality is going to be terrible. This is what happens when your suspension is oversprung.

My roommate had OTS, stock valved Konis and 400lb Front/500lb Rear springs - the ride was absolute crap. VERY rough, bouncy, jarring.... just bad. If you plan to run rates above 350lbs, it would be wise to look into an entry level coilover or re-valved dampers.

But with 'street' rates - the Koni/GC setup would be good for your application.
