Aftermarket Assassins 2026 Kawasaki Teryx H2 S1 Clutch Kit

Fits all 2026 Kawasaki Teryx H2 Supercharged models 250HP

• Get ready to transform your Teryx H2 with just a clutch kit! Honestly, every H2 should have one of these kits for power and CVT longevity. Read below for more information.
• Adds +3 to 5 PSI of boost pressure (roughly 20-30 HP) at low elevation on stock tires due to increasing the peak RPM. You'll see even bigger boost/power gains to be seen when running larger tires, paddles, and/or riding at elevation.
• S1 kits include our AA Recoil magnetic adjustable bushing style clutch weights, AA red primary spring & setup guideline.
• Our S1 Clutch Kit packs a huge punch! No matter the terrain, they hit hard and just keep pulling for days. On the rocks, trails, dunes, or at the race you'll notice wicked acceleration and instant clutch response when getting back into the throttle after hammering that corner. In the dunes, you'll see the same benefits, but also have much less bogging when climbing that big dune. The machine will hold RPM so you can get where you need to go, and get there faster! Going mudding? Our mud setup will help turn those tires through the thick and deep with much better RPM and wheel speed that's key to climbing out of that hole. Are you a rock crawler? Our smooth engagement and precise feel down low will give you the confidence to tackle any obstacle. We have a huge amount of CVT knowledge with these Kawasaki's (since the 2020 KRX), a great passion for the sport, and spent many hours testing different setups in the real world. We know you'll be extremely pleased with the performance gain from our clutch kits!
• The Teryx H2 is a very potent machine at 250 horsepower. That horsepower is rated at 9000 RPM, which the stock vehicle does not hit until nearly max speed. With a supercharger, you have a direct link between boost and engine RPM. This means the faster you spin it and the quicker you can get to peak RPM, the more boost/power you will make. The OEM setup runs around 8200 RPM at 55-60 MPH, then slowly builds out to 8700 around 75-80 MPH and creeps out from there. With our S1 clutch kit, you will notice it builds RPM much quicker, and hits roughly 8800-9200 RPM at 55-60 MPH. This results in drastically faster vehicle response and acceleration as we are adding boost (via RPM) without even tuning.
• We spent many hours on our weight ramp profile when testing with other Kawasaki models that use nearly the same clutch, which transferred right over to the Teryx H2.
• OEM clutching is subpar, and especially the weights. With only 30 miles on our vehicle (when we first tore it down), we noticed a ton of wear on the clutch weights. This is due to the soft material the factory uses. The OEM weights have a ramp on the end which is known to cause issues with wearing the tips of the weight. Our weights will provide much greater durability and longevity. Based on what we've seen so far, it's best to remove the OEM weights and install ours as soon as possible.
• Our setup guideline will let you know how to set your weights for stock horsepower, tuned horsepower, 32-37" Tires, paddles & more.
• Are you a cruiser/crawler that does not care as much about peak power? We have a cruiser/crawler clutch setup within our setup sheet as well. This gives you the most bottom end belt pinch possible and will cruise around at a lower RPM. This does pull peak RPM down, so power sacrifices.
• Fully adjustable magnetic weights are easy to use and adjust
• By design, our clutch weights have more tip weight mass with a more aggressive profile, so they grip the belt harder and accelerate faster... yet still crawl even better than OEM.
• A must-have item for any Teryx H2! Especially needed when changing to larger tires, tuning your machine, or running paddles
• Cooler running belt temps from a more efficient power transfer which results in longer belt and clutch life
• Huge acceleration gains and better power transfer to the rear wheels! See product images for dyno and acceleration results. For acceleration runs, we went from 6.02 seconds to 5.46 seconds in a 0-60 run. All runs were done in groups of 3 or more and used the average/repeatable run. All runs were done on pavement in 4wd for consistency. On the dyno, stock runs were done at 8200-8300 RPM which is where they run from the factory until top speed where RPM climbs out.
• Smoother than stock clutch engagement
• Our Recoil clutch weights are easily adjustable with simple magnets. They have a custom AA profile, the BEST coating on the market (nitrocarburizing) which has increased wear resistance, improved fatigue strength, and added surface lubricity. These clutch weights also offer great performance, and the ability to tune for many different applications or modifications in the future, without the need to buy extra parts. The magnetic weights are the best option to properly place the mass where we need it on the weight for best performance for your application.
• We found the stock secondary clutch to work very well, this kit is just for the primary clutch.
• Make sure you check peak RPM @ 55-60 MPH, it should be 8800-9200 RPM for peak performance. See here on how to test: Hyperlink
• Overdrive Revolver Cover Option: This will allow for higher top speeds, bringing back top speed lost due to higher shift out RPM(for boost/power), strengthens the clutch, and helps clutch reliability.
• You will need belt removal bolts (M10-1.25 x 50mm) which we have as an optional item
