Rear shocks can improve your ride by reducing bounce and retarding roll in cornering, esepecially with a load.
After my long trip to KS City for the SBR last year, the two things I came away with after 3000 plus highway miles was; that I need to add a front sway bar and rear shocks. While the truck does fine in the 35-45 mph range, get her up to 55 or 60 it can get a bit exciting in traffic on bumpy highways with humps and camber changes.
