Just by the photos the leafs out of the truck look better, thinner tappers at the ends which might smooth out the ride but unless you know what spring rate they are your guess will be as good as mine. You might want to have a spring shop test the spring for rate and see what it comes out as or do some trial and error and mix both packs up picking the leaf's you feel are softer. Other wize stickem in if you don't like them switchem back.
