Since throttle becomes more sensitive after the install of the springs mine likes being shifted above 2000 the engagement of the clutch is a lot smoother.

You will see.

I got my 4k kit from pdr I spent the 250 for it to get all 12 60 pound springs the gov kit was easy it was the valve springs that were hard to put in and like was said earlir make sure everything is clean and get the old spring parts out

sweet as soon as i get the money goin to get the 60lb springs. do i need all 12 or just on intake or wat?

all 12

they run just over 100 right around 120?
