HD Front telescopic suspension design hasn't change since ...... well, ever.
So yep, still safe to use in current front forks.
I'm getting ready to head over to a friends house to change up my front suspension.
FLST upper tubes (1.5" shorter than stock),
Progressive Monotube internals (lowered 2", for a total of -3.5" from stock).
I'll be using ATF for the fluid on reassembly.
Dave is right on not using Type-F, use Dexron.
