Nose Cone Spacers
Is it a spacer to prevent the 5-vanes' tendency to thrust the ski to the right all the time?. I think I was reading something about that in another thread..
They have o-rings in them where they mate with the cone. So no rubber or paper gaskets.
Is there any performance gain using them?

According to Chopper City:
CCS Brand Stinger Spacer
Designed for 94 and newer SL's, the Stinger Spacer moves the pump tail cone deeper into the nozzle, reducing the gap between the cone and nozzle. The thrust is concentrated for greater force.
Works especially well with the CCS pump wedge, increasing acceleration and throttle response with more efficient thrust.
Inexpensive speed secret.

I have been looking for one of those spacers. I figure that if I put the 4" pump extension after the stator, like on a 785, the spacer will help move the cone further into the nozzle and make up for the additional space. Problem is they are hard to find. Hang on to those Bowsniper.

Wetwolf. In addition to providing the advantages of a fixed TAIL CONE spacer, the ATT changes its effective length as engine RPM (and jet pump pressure) rises.
The result is good low end thrust and rough water hook up, and good top speed.
The ATT for the Pro (which has the pump extension ring behind the stator) not only reduces the excess cavity volume behind the stator, it effectively reduces the exit nozzle diameter at high speed, resulting in higher top speed. So you can adjust (or bore out) your pump nozzle to optimaze low end hole shot, then use the AAT to bring back the top end speed that otherwise would be lost due to the enlarged pump nozzle.
