What it does most, is move the pivot ball...stock is inside the transmission. hurst moves it to out and above the transmission...that's where the 'short' comes into play.....the arm is phiscally shorter because of the relocation of the pivot.
so....shortend shift throws(1-2, 3-4 and tighter and narrower 3-4, 4-5), more positive shifts, the awesome clicking sounds it makes...the awesome gears turning sound from the trans gears meshing is awesome...but sometimes noisy at times.
I love my hurst that i got off craigslist for $120. Had it on the truck for 1.5years or so...absolutely love it.
