This clutch features a "Wide Spread Pin" or WSP style spider. It moves the weight circle to a larger diameter to offer more belt grip with lighter weights resulting in a clutch that will rev up faster, handle more power and have great durability on the track or trail. This three arm clutch is ideal for applications from stock to about 350hp range. In trail form we got lower belt temps and way better belt life on a 280hp tune.
In our testing we also found huge gains drag racing with our newly released "Hump Back Raised Notch" cam arms. However we have designed the clutch to still be very versatile in the fact that you can still run all of the original designs of STM cam arms and most aftermarket cam arms that utilize a 5/16" pin.
With the Procross platform we have found that running an 8.5" diameter primary and 11.25" diameter STM Gen 1 secondary with the XS-822 belt offers the most efficiency and also allows for 18% overdrive thru the clutches so you can run a lower gear ratio and still achieve the same top speed, resulting is cooler temps and longer belt life in both racing and trail applications.
The clutch includes belt and spider shims, so you can change your belt to sheave clearance and cam arm to roller clearance independently.
This clutch uses all TRA (Ski-doo) style or PS (Polaris/Arctic Cat) style springs.
The larger clutches fit under the body panel without modification.
We can also setup the clutch to use the stock belt and stock secondary.
Cam arms and Springs are sold separately.
The drag racing tied bearing brace is also available for this primary, but can only be used with solid front motor mount and the Gen 1 STM tuner secondary. Body panels will need to be cut to fit the Brace.
This clutch can also be made to work on the older Z-1 sleds.
This is a great option for the Z-1 Swapped RZRs with our Conversion Tuner.
