Duh, what is the difference. Guess I don't know.

Crash boxes you have to shut the motor off to get in and out of gears...there is no hp loss to speak of with a crash box plus they can handle major hp ...many trans fail under loads...boxes are very hard to deal with in pleasure boating.

unless you have air shifted crash boxes

I guess that is why they are so difficult around the docs eh.

Of coarse unless they can be shifted!

Any problems with the scs shiftables....anybody already do this rig out?
