The truth is shock absorbers can only dampen or suppress compression and rebound when the truck hits bumps. Shocks are not going to moderate harsh suspension. If anything, tight shocks will make the ride stiffer. I've never owned a Gen I Ram but have read and heard that they rode pretty stiff.
My personal choice for long life and good ride in Gen II and Gen III Rams is Bilsteins. Like Denny Day above I've run them on two previous Rams and am getting ready to install them on my current one as soon as the UPS truck from Geno's arrives.
