STM Secondary Clutch Polaris Sportsman & Scrambler 850/1000 and S models

STM Secondary Clutch Polaris Sportsman / Scrambler 850 / 1000 / 1000 S

STM Powersports from Michigan (US) is the No. 1 clutch manufacturer on the US market. The precisely CNC manufacturing from the full aluminum distinguishes the patented clutches significantly from all Asian manufacturers.

80% of US tuners and racers rely on the precision and multiple conversion options of the clutches. Jay and many of his racing colleagues trust the know-how of the factory teams and racers from USA for years.

Great advantages of STM Secondary Clutch:
- better acceleration
- triple support, thus no tilting of the variomatic discs
- precise tuning
- better cooling of the clutch and belt
- no belt slippage, less temperature
- Helix curve available as desired, is critical to performance
- Aluminum better conducts temperature to the outside

Of course you can combine the Secondary Clutch with all other manufacturers.
Note, however, that the combination with the series Primary Clutch or other suppliers should be fine-tuned to your driving style. The fine-tuning is in the customer's area! It is to be made on the basis of spring and weights on the primary (if necessary)!

Best results are acquired when running both the STM primary and STM tuner together.
If you order both clutches, JAY PARTS will give you the matching GATES REDLINE CVT drive belt as a gift on top!***

Comes with a belt removal tool and bolt for installation. The original screw can be used for installation, but we recommend new screws!

The very extensive tuning selection of springs and Helix curves offers countless combination possibilities. Use our know-how for your optimized STM clutch!
By specifying your vehicle data such as model & year of manufacture, modifications to the engine and transmission, tire type and dimension used, as well as your driving stlye (predominant use), it is possible for us to put together your STM Clutch in the best possible way together with the technicians from STM Factory.
