DETAILS

Our Stage 2 clutch kits consist of our magnetic adjustable primary weights, primary spring, secondary spring, smooth shift Teflon washers, and a custom cut helix. You also have the option to go with our torsion conversion kit which also includes our torsion spring cup. With our expert clutch tuning knowledge, and the right components at hand we gain huge all-around clutching performance. For mountain riders, you’ ll see our clutching hold RPM much better and track speed will increase because of this. On the trail, you’ll have insane upshift, and incredible backshift due to our weight profile, custom springs, and custom cut helix. This results in an amazing corner to corner performance that simply can’t be matched!

We have two different secondary setups depending on your preference, and budget. The standard, stock style compression spring we offer has a much better rate and is designed to work with our custom helix. This standard setup works extremely well. One key component to consistent clutching and quicker shifts in our standard kit is our smooth shift Teflon washers. These washers are stacked inside the spring cup and allow free movement of the flat side of the spring. If you want to take things to the next level, we have our torsion spring conversion kit. This is the style spring shown in the second image and requires a 1/4" hole drilled in your secondary clutch to catch the end of the spring. This kit comes with a new roller hub that has 3 holes for the torsion spring settings. The torsion spring shifts out further and has even better acceleration and consistent shifting results than our standard setup. If you don't want to spend the money on the torsion kit right away, its a simple $150 upgrade at any point. No matter where you ride, we have a clutch setup that will perform above and beyond your expectations. Please select the kit which is best for your altitude and performance modifications.
