Dalton's patented "Quick Adjust" Cam Arms are now available for Arctic Procross models with Team primary clutch. These flyweights make accurate primary clutch tuning easy. Only the highest quality materials and processes are used. The new QA2 series come with a high quality bushing and offer up to 7.4 grams of adjustment.

81g and higher base weights have the “wide” design to achieve higher weight increments.

*Most common for 2016 800 Procross 129” trail applications was QA2-70. Most common for 2016 trail modified turbo (Suzuki engine) with aftermarket pump gas reflash to the ECU was QA2-84. Many with 2017 Thundercat 3 cyl. turbo with re-flashed ECU (trail) are using QA2-73.

*This seems to be some of the more popular applications as we hear it. Different springs, helix, HP, components, tracks, gearing, etc. have effect. The notes listed by the flyweight selections are for your reference only. Dalton Industries is a component supplier for racers, those who tune their own clutches, and clutch kit companies. We do not, and have never made any clutch tuning “kits”, packages, or recommendations for snowmobiles. The parts you choose to use will be your own decision. If you prefer, there are more notes and some clutch kit companies listed on the FAQ page of our site here.
