Air Dam at one point in time sold clutch shoes for the Prowlers that had more surface area, and less slip! 101 coming up!
The Prowler uses a wet clutch that helps the belt life as power is applied gradually as rpm's climb. The wet clutch has a stall speed of approx. 2,100 rpm. Once the wet clutch is transferring power to the primary clutch things start to happen! The CVT comes into play. As the primary starts to spin, the clutch rollers start to move the belt higher in the primary clutch, and lowering it in the secondary. The clutch is fine tuned with different weight rollers. I use heavy clutch rollers for street duty (grey 27 gram), lets me cruise at a decent clip without spinning the motor at high rpm. When I ride the sand dunes I use my facory rollers that are fairly light (red 19gram each) in order to keep the rpm up in the power band. For trail riding I use 21 gram rollers and a higher stall speed wet clutch setup. There has been several firms that made wet clutch delete kits, but they are somewhat expensive at 1,900 dollars! I have found that the factory rollers are about 1/2 the cost of aftermarket rollers.
red rollers = 19 grams = 6000RPM AC # 0823-164
blue rollers = 21 grams = 5500RPM AC # 0823-167
green rollers = 23 grams = 5000RPM AC # 0823-170
white rollers = 25 grams - 4500RPM AC # 3402-483
grey rollers – 28 grams - AC # 0823-295
black rollers – 33 grams AC # 0823-298

19 gram roller - red - prowler 09+700 - part number: 0823-164
21 gram roller - blue - various H1 engines - part number: 0823-167

33 gram roller - black - 10+ Tcat mudpro - part number: 0823-298
These RPM numbers associated with each set of weights is only a close guess. every machine will respond differently depending on altitude, tire size, and power adders. the more power you have, the heavier roller you can run for a faster upshift, and more RPMs. if i were you with that power you have, i would run the reds at the LEAST, and possibly even lighten up a set to get them even lighter. in the dunes to run ballz out, about 17-18 grams is where an H1 motor needs to be, and my stage 2 fixed plate work even helps the shiftout even more. it helps keep the rollers lower in the shiftout range, keeping you in a lower gear longer, but allowing you to build the RPMs you need for power, which allows the engine to rev into the power band, and not upshift too fast and bog the motor down.

Info.. From Airdam post in one of my thread's
C-1 is 34 degrees of preload on the spring so yeah its a little more than the others here is a graph to show it all to you
with the helix facing upwards, you turn the top movable sheave clockwise, tightening the spring up giving the spring a pre-load to snap the clutch closed.
the A,B,C settings are incremental in 1,2,3,4 hole positions on the helix itself. meaning if you leave the spring in the
