SKU: 113-1016-1

  • Fits all 2020-24 KRX 1000 models
  • **2025 models use a 3 arm clutch instead of 4 arm, for 2025 models, see that specific listing***
  • Lock and load your Kawasaki KRX 1000 and get ready for some serious kick!  The KRX 1000 is a great machine, but Kawasaki left a ton of room for improvement on the table.  This simple kit is the best way to wake up your KRX 1000 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 2 clutch kit compliments the tuning perfectly by more efficiently transferring power to the wheels and ridding yourself of the very lazy factory clutching setup.
  • Kit includes: AA custom tuned PV3 tuner and Stage 2 Clutch Kit.
  • Big horsepower gains! The KRX factory timing map is very de-tuned which allows us to easily wake things up
  • Quicker throttle response and power delivery
  • Throttle by wire tables are modified for better response, especially in high range.  Low range throttle mapping is a little better, but still left mild for good crawling. 
  • Full throttle/power in reverse (factory limits reverse throttle)
  • AA's wicked timing curve built for 91-93 octane fuel
  • A great fuel curve that gives much better low end (as well as all around) power as the factory map is very lean in key areas.
  • Accelerator enrichment is optimized for better fueling and vehicle response when stabbing the throttle
  • Fan on/off temp lowered to 185/180 degrees Fahrenheit (Stock is 189/183)
  • Winter tunes (runs hotter but safe coolant temps) available for those with cabs/heaters in cold climates. Easy to switch when seasons change!
  • Seatbelt limiter disabled
  • Speed limiter removed in low and high gears
  • Rev limit at a safe 9800 RPM (Stock is 9500 RPM)
  • Best peak power when tuned is 7000-7300 RPM at wide open throttle around 50 MPH in a full power run
  • Very easy to use tuner that can also check and erase most trouble codes
  • Easily data log 25 parameters with 1 push of a button and review on your windows computer later
  • No mess of having to send in your ECU, and a safer way of programming your ECU (easily go back to stock tune)
  • Mount using the supplied dual lock Velcro
  • Level 1 Tune: Built for the OEM exhaust (cat removed is okay) and 91-93 octane.  Gains 10 RWHP in some areas, and on average 7-8 RWHP when combined with our clutching. This takes your KRX from roughly 112 factory rated crank HP to 125 HP.
  • Level 2 Tune: Built for an aftermarket exhaust (slip-on or full system) and 91-93 octane.  Gains 16-17 RWHP in some areas, and on average 14-15 RWHP when combined with our clutching and exhaust. This takes your KRX from roughly 112 factory rated crank HP to 135 HP.
  • Race fuel tune 95-100 octane maxes out our timing curve to where we see peak power.  This gives you another 3-4 RWHP on average over the pump gas tunes. 
  • More tunes are coming, if you have any specific needs please let us know!
  • Why 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.
  • Our Stage 2 KRX 1000 clutch kits pack a huge punch!  No matter the terrain, they hit hard and just keep pulling for days.  On the trail 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, 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 KRX 1000 has some clutching issues right out of the box because the OEM weighs are soft.  Being these vehicles are geared so low, the clutch constantly runs at full shift over 55 MPH.  Being at full shift for so long wears the weights away at the tip, and will groove them.  This makes the vehicle want to sit at full shift, and shift inconsistently.  Our weights go through two hardening processes and are through hardened for the most longevity possible. They have no bushing as it's not needed with the hardened weight, which also makes them last longer.  Not only that but they are fully adjustable for different tires/modifications and perform better because of how the mass is placed on the arm.  
  • Stage 2 kits include our AA Recoil magnetic adjustable clutch weights, AA dark green primary spring & setup guideline.  
  • Our setup guideline will let you know how to set your weights for stock horsepower, tuned horsepower, 30-35" Tires, paddles & more.
  • Fully adjustable magnetic weights are easy to use and adjust
  • Adjustable from 84-100 grams, and up to 120 grams for turbo applications if you purchase our optional Slug Magnets
  • By design, our clutch weights have more tip weight mass, so they grip the belt harder and accelerate faster... yet still crawl even better than OEM.
  • A must-have when changing 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
  • Big acceleration gains an better power transfer to the rear wheels.
  • Close to stock engagement which is very smooth (Higher engagement springs available if needed for racing)
  • 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 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.
  • We found the stock secondary clutch to work very well, this kit is just for the primary clutch.
  • Make sure you check peak RPM @ 50 MPH, it should be 7000-7200 RPM for peak performance.  See here on how to test:  https://aftermarketassassins.com/tech-blog/f/clutch-testingverification#
  • See installation video here:  https://www.youtube.com/watch?v=Vop-L1y0IK4
  • You will need belt removal bolts (M10-1.25 x 50mm) which we have as an optional add-on item
  • Highly recommend replacing your factory belt with our AA Stryker Belt for longer belt life and consistent performance.

Great for aggressive chewers
Style: Gorilla, Size: Small (Pack of 1)
My little Corgi is an aggressive chewer. She has destroyed quite a few toys that were advertised for chewers. When I received this toy I had little confidence but it has lasted unscathed. Aside from being sturdy it also bounces so we play ball with it. It is one of her favorite toys.

Strong and Great for Treats, but Heavier Than Expected
Style: Gorilla, Size: Small (Pack of 1), Style: Gorilla, Size: Small (Pack of 1)
This is a very durable and well-made chew toy with good overall quality. The material is thick rubber and holds up well to chewing. It also works very well for holding treats, which stay in place securely. The main drawback is the weight. My dog is about 30 pounds, and even though this is a smaller version, it is still fairly heavy. She tends to use it mainly to get the treats out and then loses interest afterward. What I like: Very durable material Works great for holding treats Good bounce and quality construction Cute design Things to be aware of: Heavier than expected Some treats may be difficult to insert Dogs may lose interest once treats are gone Overall: This is a solid treat-based toy that is built well, but the weight may limit how much some dogs interact with it beyond treat use.

Extremely tough!
Style: Gorilla, Size: Large (Pack of 1)
These are seriously so much better (and cheaper) than any other supposedly "strong/durable" type toy like this. We have 70lb very strong chewers and they chew through everything. Can not have stuffies. They do eventually chew through but it seriously takes awhile. Especially in comparison to other brands. I will say it says "recommended for dogs under 35lbs" but I also work for houses where I recommended these for their dogs which were smaller and they wouldn't chew on because too tough. But they also accidentally bought the large which is what I buy my big dogs. So the large is GREAT for big dogs. If you have a dog under 35lbs I'd get the size small. Also .... says you can stuff treats. You really can't. Which my dogs don't need. They just love to chew on. I call it their bubble gum because when they FINALLY get a chunk off(which again takes awhile.... as in over a week) they will fling the pieces into the air and chew on like a piece of bubble gum lol... they love it! I don't notice a difference in breath or anything but I don't use the toothpaste either. I just bought to see if tough and they are!! And again price is clearly so much better. I hate spending $20+ on a toy they destroy in a day.

Beware if your dog likes to chew
Style: Gorilla, Size: Large (Pack of 1)
It’s super cute and my dog loved it, but it didn’t last very long. My dog started peeling off pieces of it and eating it within three hours of play. If you have a dog that takes it easy on the toys I would recommend this one. Otherwise I recommend passing because there’s no way it’s safe for them to be swallowing these pieces.

Lasted pretty long for my aggressive chewer
Style: Gorilla, Size: Large (Pack of 1)
Right away I was excited with this product because of the smell, texture and thickness. Smells minty fresh which does help with breath smell. The texture is great, had smooth areas and rigid areas all while being soft and durable. The product is pretty thick, which I needed for my Pit-Bull. She doesn’t chew much but, when she decides to she is 110% in and dedicated to destroying that item. She chews through most things in less than a day. This product however lasted years before I started to notice damage. It is one of her favorite toys. She liked it so much I bought two, one for the house and one for the car for road trips. It’s the perfect toy to keep a chewer distracted inside a car, along side a deer antler, which also helps with dental hygiene. She gets dental hygiene compliments every trip to the Vet. We use multiple different things to help with her teeth and breathe but, I think this toy contributes the most to her healthy teeth. I call it a toy because she plays with it all the time. Definitely will keep buying long as they keep making it. This product is a must for all dogs, it’s almost perfect for my Pit-Bull
