This TricTrac Upgrade Kit will completely change the way your ATV Handles. The Patented TricTrac (us 7'467,800 B2) is an Automatic castor adjustment that changes the castor of the ATV while you ride. The TricTrac
was invented by Houser Racing and is well known in the ATV industry.
How the TRICTRAC Works
When the ATV is turning into a corner the front suspension compresses and
the TricTrac worm threaded shaft forces the upper A-Arm Forward. This
Forward Movement causes the castor angle to decrease and become more
negative. Negative castor helps the ATV steer into a corner better.
When the ATV is heading down a strait-away, the front suspension becomes
light and fully extends it-self, the TricTrac worm threaded shaft forces he
upper A-Arm Backward. This Backward Movement causes the castor angle to
increase and become more positive. Positive castor helps the TV feel less
twitchy down a strait-away, which makes the rider feel more stable.
What Caused The TricTrac To Be Invented
Houser Racing was doing Testing and Development with our Pro MX racer Harold
Goodman around the year 2005. At this time we were testing our Patented
Slicast ( PAT #) system, which is an independent castor and camber
adjustment. When we were adjusting the Slicast we noticed we would get the
ATV to corner great, but then it would handle terrible down the strait-
away. Then Harold would come back to the pit area and we changed the
Slicast the other direction and then the opposite happened. At this time we
figured out that our Slicast was working great because we could feel results
when we made changes. We also found out, when you are dealing with castor
you can't have both, great corning and straight-line stability. After a
week of brainstorming about this problem we decided to attempt to change
Castor forever. TricTrac was born and released 6 months later.
