Shim Kit is a great tuning device for any racer. The Shim
Kit comes with 5 shims, 3 Driver Shims and 2 Driven Shims.
The Driver Shims help to adjust the engagement point of the
Front half of your clutch. The shims are placed between the
Driver Post and Clutch Cover to adjust how far the Clutch
Roller sits from the launch point of the ramp. These shims
can be used to set your engagement point exactly where your
car and driver want it.
Driven Shims allow a tuner to change the overdrive
percentage of their clutch. By adding or subtracting shims
between the Driven Unit Sheaves you can increase the amount
of overdrive made by your clutch unit. We offer 2 shim kits,
one to fit the HP Gold Series Holeshot Clutch and to fit the
more traditional style clutches available today.
