The Ranger 800 lineup is great, but they have so much more potential! Polaris really left a lot on the plate for these machines, and we can help fill it! If your model came with a restrictor plate, REMOVE IT! Then call us up for a Power Commander 5 EFI controller. We have a custom tuned map for the Ranger 800 with no restrictor plate that increases timing and fuel to give you more power. Even if your model doesn't have a restrictor from the factory, it can still use more timing and fuel. Next you want to pick up our slip-on exhaust. For all this added power you will need to do clutching. Even with a stock machine clutching is HUGE, not to mention if you add bigger tires or horsepower it is a MUST! Our kits come complete with adjustable weights, primary spring, and the much smoother, better shifting TAS-03 secondary complete with helix and spring. Now if you want big horsepower take those same mods and add our big bore, cam, and head porting. We also offer a great turbo kit that really pushes horsepower to the next level. No matter what your budget, we can get you the most performance.... hands down!
