2018-2019 Wildcat XX / Wildcat 4XX

2018-2019 Textron Off Road Wildcat XX / Wildcat 4XX Performance Products & Parts | Speedwerx Inc.

The next generation of the Wildcat is one of the most highly anticipated side by sides in years, and from what we know so far it's not going to dissappoint! It has many features that have never been seen on any SxS as they rolled off the assembly line- standard 30" Tires on 15" KMC wheels, FOX Podium Shocks, stout RG Pro Supsension with 18" of travel, and the 998cc triple engine with a class-leading 125 naturally-aspirated horsepower to name a few.

You know we can't leave well enough alone though- we'll be hard at work developing many performance parts and accessories for this machine with the same quality, durability, and of course the Straight-Up USA Horsepower that has made us known as the Worldwide Leader in Arctic Cat Performance! We plan on offering many of the same type of go-fast parts that turned the Wildcat X into a whole new animal- from bolt-ons like our Hypershift Clutch Kits and Stainless Steel Mufflers and Headers all the way up to serious performance mods like Big Bore Kits and Turbocharger Kits, so stay tuned for further announcements on new products as the development continues...

Update 4/12/18:
The Textron Off Road Wildcat XX’s are starting to show up at dealers around the country, and naturally everyone is wanting to know more about Speedwerx performance upgrades as the machines filter out into the hands of the consumer. We’ve been working on a number of bolt-on parts and dyno testing many different configurations over the past few weeks, and we were pleasantly surprised to see the XX pull 130hp for a stock baseline number, 5hp more than the factory rating. Even better yet, our Stage 2 Exterminator Kit delivered 142hp with power and torque increases over the whole RPM range. Take note of the huge gains at the lower RPM range as well, 12-18hp more over a 1000rpm+ spread, that translates into more grunt down low to get you out of the hole quicker- it’s really noticeable just by the seat of your pants when you mash the pedal. All testing was done with 87 octane fuel, so you can save a few bucks at the pump too.
