taller pistons for your 800 CFI! Great performance and reliability gains
with this kit! Same kit fits all models 2008-Up. The kit comes with two
new Teflon coated pistons, rings, wristpins, circlips, longer cylinder
bolts, machined spacer, longer dowel pins, and two base gaskets. No fuel
controller needed. Want even more? Add our billet head kit for 160 hp
and still no fuel controller needed on Pro-R models (Ethanol setting is
For Polaris 800 motors,
2008-2014. The relatively short rods and pistons have been the cause of
the short life of the stock pistons and rings. Most machines will lose
20-30 lbs of compression after just 1500 miles of riding which causes
a loss in performance. How many miles do you have on your sled? If it
has 1500 miles or more, you're in need of this kit! The key to this kit
are the taller pistons we developed which allow less piston rock. This
reduces the stress on the piston and rings dramatically. We also extended
piston life by slightly changing the ring location, adding lubrication
holes on all four corners of the piston, and Teflon coated the skirts.
The Durability kit includes a cylinder spacer that raises the cylinder
the same amount as the piston is taller so port timing isn't changed.
The added crankcase volume even produces 6 more horsepower so your engine
life is extended dramatically while gaining you power at the same time.
The kit comes with two new Teflon coated pistons, rings, wristpins, circlips,
longer cylinder bolts, our machined spacer, longer dowel pins, and two
base gaskets. If you plan to keep your Polaris, you better get your Durability

it compare to the competitors?
1. Wossner Pistons
- Unmatched forged piston quality compared to any other manufacturer.
Other companies use Wossner but they are not the same design as ours.
2. We engineered our
Pistons .250" taller than stock to reduce fatigue on piston skirts
due to rod angles. Some people install longer rods but doing so decreases
power and costs much more.
3. We designed Gas
Ports into our piston These are small ports that allow oil film from underside
of piston through the piston to help lubricate high load areas.
4. We offset our wrist
pin .020" towards the exhaust side to reduce skirt loading during
5. We engineered a
wider ringland between the rings to reduce ring temperature.
6. The addition of
the .250 inch spacer under cylinder corrects cylinder volume for the 800
cfi resulting in more efficient power.
7. The addition of
the spacer under cylinder also lifts cylinder intake shirts up out of
the reed window reducing intake restriction and resulting in more power
during high airflow demand at high RPM.
