All new unique design that will hold the belt on high horsepower applications.  The concept of this design is to provide an improved amount of force to the belt approximately for the first ½ to ¾ of the belts shift and then release the force, once the vehicles momentum is established.  This design solves the biggest problem that all racers face from years past-- belt slip and over revving during hard acceleration.  Problem solved, Hang on!  The way it works: All  cam arms engage at the same time providing over twice the amount of force to the belt.  Once the movable sheave has shifted ½ to ¾ of its now adjustable shift the supplemental cam arms sign off due to centrifugal force that holds them suspended above the movable sheaves rollers.  This allows the  main cam arms to finish the shift and acquire the proper operating rpm.  We can now change and control the total shift in two ways.  First is by adding more mass to the supplemental arms and secondly by changing the supplemental roller diameters. Yes, it's that simple.  By decreasing the roller diameter the supplemental arms let go of the shift earlier and by increasing the roller diameter the supplemental arms shift longer before release.  During testing we discovered that by increasing the roller diameter by .125" at one time, the initial over revving during hard acceleration would drop 500 rpm with no change in engagement rpm. This option is so simple but yet effective by just a 10 minute roller change.  Uses any cam arm available on the market utilizing our retrofit pin design.  The first stage cam arms will be provided with the Rage (second stage cam arms are sold separately).  They will be capable of adding additional weight for adjusting that killer hole shot. A set of three different size rollers will be provided.
