April 2012 - Spring Nationals of the
Midwest Chase'n Race'n ProKart Tour
Winfield, KS.

"I qualified 19th for the Pro Animal feature paying $1000 to win. In the 20 lap feature, I passed 18 karts with the help of only one caution to take the win. I was on a 2007 Phantom Icon racing everyone else on 2012 Tritons, Impulses, and other karts. I was using a two disc Vortex Roller Lever clutch. I ran Animal 340 and Animal 375 also that day. I won Animal 340 and placed 6th in Animal 375."

"The clutch performs perfectly race after race. Running an eighteen tooth sprocket really works the clutch hard but the engagement was always smooth. Even after a bunch of caution laps it never overheated. It's nice to know I don't have to worry about the clutch chattering or slipping unlike others I have had in the past. After making the switch to a two disc Vortex Roller Lever clutch I won't ever change again. It's simple to work on and setting the engagement can easily be done at the track with common tools and no guess work. Thanks SMC for a great clutch to put my Faster Motors power down!"

Thanks, Branden Zinser

What's New!

SMC will continue to lead the way in clutch technology in 2011. Similar to the interchangeable clutch sprockets, aluminum drum, Vortex torsion springs and eight tab tab disc we created in the 90's and the SMC Axle Clutch created in the 80's, we will continue to design new products to enhance the kart racing experience.

SMC Drums

SMC announces all Vortex Clutches will only be shipped with the eight slot drums. Obviously you can use either four or eight tab discs but the intention is to double the life of the drum for four tab user. The reason for this change is to go along with our spend less philosophy. The eight slot drum will double its life with the four tab clutch discs i.e. after four slots wear out, the clutch discs can be indexed 45 degrees and the second set of slots employed.
