CLUTCHING
PIONEER COMPOSITE ROLLER
*Strong lightweight design!
*Easy to install or remove!
*Improved shifting!
*Self centering cover!
*True spring height!
*Thoroughly tested!
*Available now!
The Pioneer Composite Roller initial concept has been tested for several years. Shifting is extremely smooth, and back-shift (throttle response is instant). The roller design reacts quicker and is not as sensitive to load changes as the stock fixed button design (which relies totally on friction to work). The PCR design is the easiest roller to install on your YVXC secondary, and features several improvements over current designs. Self centering cover keeps the bushing in alignment with the moveable sheave bushing for smooth consistent shifting. True installed spring height keeps the side force the same as stock keeping the belt "hooked up" at all times. Uses a special barrel type mounting nut, so simple you don't even have to remove the stock helix mounting studs! We've got an excellent snow tested set-up for the RX-1, instant back-shift and throttle response, along with greatly improved acceleration and increased top end. We also have trail tested calibration for most other Yamaha models! Specify year and model when ordering. For installation only three holes need to be drilled and tapped, helix acts as a template, the holes do not affect anything should you choose to return the clutch to stock. Kit comes complete with drill, tap, roller plate (with bushing), helix, barrel mounting nuts, helix mounting bolts, and washers.

PERFORMANCE CLUTCH KITS
Bruce Schrader has been tuning clutches since 1978. His experience has given him a great understanding of how the centrifugal snowmobile clutch system works. These clutch kits are designed specifically for the performance minded trail rider, looking for the best possible acceleration while maintaining the back-shift needed when going through the bumps, or coming out of a corner. All kits are designed under real snow conditions, and include all the necessary components and instructions for easy installation.
Apex & Attak
The Apex & Attak are both clutched more for touring than for performance. We change weights, primary spring, and helix. When installed our kit improves acceleration, along with giving the sled a “performance” feel. Standing and roll on acceleration is much better along with improve throttle response (back-shift).
Vector
& '06-'07 Nytro
Give your sled the performance
to run with the 2 strokes! The clutching of the 3 cylinder four stroke is
very linear. By installing one of our clutch kits you’ll get the hit out
of your sled that will dramatically improve acceleration, getting you from
point a to point b much quicker. Kit features new weight, primary spring,
billet helix, and secondary spring.
RX-1
This
kit dramatically improves acceleration and throttle response. The RX-1
suffers from an under-rev, by installing our kit the engines R’s are
increased, putting more power to the snow. Also by increasing the R’s
back-shift (throttle response) is also improved. Kit comes with new
primary spring, rollers, billet multi-angle helix, tuning rivets, and
instructions.
SX Viper
The
Viper suffers from an over-rev. The engine puts out maximum horsepower at
8500 Rpm’s, often we’ve seen them run up to 9000 Rpm’s on the trail.
The over-rev not only hurts performance but also reduces fuel mileage. By
getting rid of the over-rev acceleration, and all round performance is
improved along with fuel mileage. Kit comes with primary spring, secondary
spring, billet multi-angle helix, tuning rivets, and instructions.
RX Warrior
The
Warrior suffers the same fate as the RX-1, the stock clutching causes an
under-rev, not allowing the engines peak power to be put to the snow,
along with sluggish throttle response. Our kit gets the R’s up resulting
in a much flatter shift, improved acceleration, along with a much better
back-shift, which greatly improves performance in the trails. Kit comes
with primary spring, secondary spring, billet multi-angle helix, tuning
rivets, and instructions.

BILLET MULTI-ANGLE HELIX'S
A multi-angle helix is designed to improve your sleds acceleration while maintaining back-shift. The initial angle of the helix is increased to compensate for the significant torque increase of the newer two stroke engines. As the RPM’s and speed increase, the helix angle drops, allowing for improved back-shift at higher speeds where the torque increase is not as significant. The first number is the initial angle, the point at which the helix is placed with the clutch in the closed position. The second number is the full shift angle, the helix angle changes at a steady rate until reaching this angle at full-shift. The quality of these helixes are equal to or better than any on the market at a lower price.
Available angles:
43/39, 45/39, 47/39, 48/40, 52/40, 45/41, 47/41, 49/41, 51/41, 48/42, 47/43, 49/43, 51/43, 53/43, 49/45, 51/45, 53/45, 51/47, 53/37
Price: $84.95 each, includes bushing
WEIGHT TUNING RIVETS
These tuning rivets allow you to change the weight of the primary clutch weight to change the shift RPM's. By increasing the weight it will lower shift RPM, by reducing the weight it will increase ship RPM. All rivets listed by set of 3. Long rivets are for the newer heavy 4 stroke weights. 4.5 rivets will work in all weights.
