my take
have had bilsteins on my Dakota, 03 2500 diesel, 04 hemi 2500, 06 2500 diesel, and a lot of my cars (mostly saabs) and have liked them very much. they ride a little more firm than stock and have no adjustment for dampening. they will last forever (warranty aside). great truck shock and they seem to be everyones choice. i just wanted the flexibility in damopening, that's why i went with rancho.
would recommend the bilsteins to anyone who wants a good truck shock for a reasonable price.
