Does anyone know the difference between the Small Block coil Spring and the
Big Block coil spring? Is the BB stiffer/taller?:confused:

i run a bb spring from whitney for a while,replaced with a sb spring from napa.ended up cutin the sb spring to get the ride height 2 coils.the bb spring is pretty tall compared to the sb spring.i still have that bb spring somewhere.

BB spring is both taller and stiffer. The extra stiffness is very little though, usually around 25-50# rate difference.

Thanks for the info guys, I kind of figured the BB spring was taller
