You have struts in the fronts and shock absorbers in the rear. It's hard to say if they are the cause of your "rough ride" or not without driving the vehicle and inspecting the vehicle. A number of other things can cause a rough ride, too, including bad or over-inflated tires, worn or broken coil springs and/or bushings. The bushings in the rear suspension's upper and lower links are especially prone to failure and will adversely affect ride quality. You might want to get professional auto technician to inspect your vehicle.
As far as suspension lifts, 4x4parts.com has options for Nissan trucks that would be worth looking into.
