They made the HP60 from 78 to current in F350's all are kingpinOriginally posted by mr.n
Yes! now we need the years...
78-79 had longer short sides and are more desireable, in leaf spring setups tires larger than 35's will mash the springs when turning.
in 1999 ford put HP dana 50's in the 250 SD's they are also ball joint (these are junk compared to the 60) they use D44 guts.
I'm still looking for a pair of these HP60's at a reasonable price.
