BMP Stage 2 clutch kits have many benefits over stock
Not only does it produce excellent performance gains but belt life is also increased dramatically The Arctic Cats are known for a short belt life and at almost 200 dollars each that is hard to swallow The Stage 2 kit fixes that problem and gains big performance in the meantime! These kits will allow the clutches to go into full over-drive, unlike stock, which does not even reach a full 1:1 ration Track speed is increased by 4-5 MPH in the mountains, and 6-8 MPH of top speed on flat land We achieve this by changing the stiff, stock driven spring, with a torsion style spring The stock driven spring actually coil binds, stopping the shift With the torsion spring, full shift out is achieved The torsion spring will also allow you to adjust the driven spring tension for quicker upshift or backshift if you desire, though we do supply recommended specifications with the kit The helix and adjustable billet end cap are machined from aluminum with our custom cut progressive multi angles The primary clutch utilizes the BMP Goldstar magnetic adjustable weights These weights hit hard on the bottom end yet are very smooth for cruising and provide quick throttle response The weights are adjustable with a unique magnet design allowing up to 22 grams of adjustment per arm We provide specifications of how to set up the clutch arm weight with each kit The adjustable weights allow you to precisely fine tune your sled or adjust for modifications and different altitudes For example, if you added a performance pipe, big bore, or turbo, you would simply add more weight to the Goldstar clutch arms The 4 weight positions allow you to put more weight towards the heel or tip if you want to change your shift pattern for a harder hit out of the gate or more top end pull Lastly, we change the primary clutch spring to increase the engagement slightly and help for quicker back shifting The Stage 2 clutch kits are simply the best modification for clutch performance and belt longevity on your Arctic Cat snowmobile Great performance, cooler clutches, and much longer belt life This truly is a must-have modification Low Alt = 0-3000 ft., Mid Alt = 3000-6000 ft., High Alt = 6000+ ft.
