Suspension question

[GMCRanchTruck]

I need some input/help from you guys. I am currently rebuilding and restoring the front end of my 1970 GMC 3/4 ton truck. I am not converting any of it to 1/2 ton parts I want to keep the towing capacity. I would like to add a shock (front and rear) that helps smooth out the ride a bit. Any suggestions from the truck community out here as to which shocks you have used in the past that worked well? I'm not expecting a smooth ride here, just looking for good quality shocks that help with the ride.
