How many miles on the truck now? What kind of driving do/did you do with it? Do you use it like an actual truck? Were you satisfied with Bilstein?
Bilstein makes great shocks, and 70k could be a good service life, particularly if the truck was used hard. Otherwise, there's KYB MonoMax and Monroe Reflex, and Gabriel Max Control. Bilstein also has the 5100 shocks.
