The Teryx H2 is a great machine and the current king of the HP wars but Kawasaki left a ton of room on the table for improvement. This simple kit is the best way to wake up your Teryx H2 as it comes with our proven ECU tunes which are loaded via the DynoJet Power Vision 3 ECU tuner. The tunes add some amazing horsepower from low end to high end RPM and really give your machine that \"snap\" you're looking for. Our AA Stage 1 clutch kit compliments the tuning perfectly by more efficiently transferring power to the wheels, ridding yourself of the very lazy factory clutching setup, and allowing for higher RPM for more boost. With our free flowing exhaust we're able to pick up even more power while holding RPM for longer pulls with less chance of detonation due to less heat retention.\u003c\/p\u003e\n\u003cp\u003eExcellent horsepower gains especially when paired with clutching and a free flowing exhaust. The Teryx H2 gains power based on RPM, as boost increases when you spin the supercharger faster. Clutching is the biggest performance gain, but you need good tuning to go with it. The OEM calibration has many areas that need to be improved upon when running at a higher RPM as the timing suffers, the throttle pulls back, and air\/fuel ratios are not favorable as they are meant to decrease power. Not only that, but a higher RPM rev limit is critical for overshoot\/top speed when clutching at a higher RPM.\u003c\/p\u003e\n\u003cp\u003eWhy AA tunes over others? We have been tuning UTV's with CVT clutches for a long time, longer than almost anyone in our field going back to the 800 RZR. Tuning a CVT vehicle properly is not an easy task as you have so many variables at one time. We spend the time to wheel dyno (with actual UTV tires) correctly per modification, and have advanced ECU calibration and clutching knowledge to do so. Every change in horsepower can result in us changing clutching several times. We also develop most of our supporting mods so we know everything works correctly, and build parts to fit the vehicles needs. Lastly and honestly the most important; we then back up our results with real world data logging on local trails and our facility on 110 acres. It's this combination that truly makes the difference and why AA normally has a faster vehicle with the same or less rated tune horsepower.\u003c\/p\u003e\n\u003cp\u003eOur 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\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eOEM clutching is sub par, 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.\u003c\/p\u003e\n\u003cp\u003eOur 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 modification 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdjustable Sound:\u003c\/strong\u003e Choose our Stealth Cap design or Electronic Cutout. With the exhaust fully open, the sound is mean and somewhat louder. Close the electronic valve or install the Stealth Cap, and listen to the sound level drop, yet still have an extremely good tone. We tested back to back several times to see if capping one outlet changes power at 9200 RPM, and no change was shown, though you will see a little more power fade with one outlet capped when running wide open for long periods of time. Even without it capped, you will see HUGE gains vs the restrictive OEM exhaust.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCurrent Exhausts are a slightly less refined version:\u003c\/strong\u003e We are using a muffler body we designed and have for the Pro R models which works extremely well. You will notice a capped center exit port on this exhaust which actually works well as a reverb chamber. This is out of view when installed. Our later version exhaust coming late winter 2026 will not have this center port. Since exhaust made such a big performance difference, we wanted to offer what we currently have as it's a minimal cosmetic difference compared to what we'll offer down the road.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eElectronic Cutout + Spark Arrestor:\u003c\/strong\u003e This requires wiring our switch to open\/close the passenger side outlet on demand. This also includes our spark arrestor for the drivers side outlet, making you forestry legal with the cutout closed. This is our preferred option!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStealth Cap + Spark Arrestor:\u003c\/strong\u003e This is a manual style cutout as our stealth cap blocks the passenger side outlet, and the spark arrestor installs in your drivers side outlet. You can remove the cap easily by removing the rear plastic and going wide open at any time. Keep in mind this option would only be forestry legal when running the cap + spark arrestor, but you can purchase a 2nd spark arrestor if need be.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eThe OEM calibration has a VERY rich fuel curve up top, extremely low timing, and pulls throttle at higher RPM.
