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 Kit shipped out today! 6 hp gain with no EFI Controller!

How does it compare to the competitors? Many people ask how our durability kits compare to everyone else's. Truthfully some other companies kits do work; however none of them have engineered all the features that we offer.
