SPI Piston Kits For POLARIS 550 SUPERSPORT 1999-2008 73.25MM Big Bore
SPI Piston Kits For POLARIS 550 SUPERSPORT 1999-2008 73.25MM Big Bore
Description:
- This bore is 0.25MM bigger than stock
- Engineered to provide the best possible path for combustion chamber heat transfer to the cylinder walls
- All of our pistons, rings. pins and circlips are manufactured to OEM specifications
- All individual components are interchangeable with original parts
- Piston weight is comparable with original piston
WE ARE PROUD TO BRING YOU THE NEXT STEP IN THE EVOLUTION OF PERFORMANCE POWERSPORTS PISTONS. OUR NEWEST LINE IS MADE FROM A SPACE-AGE ALUMINUM ALLOY WHICH MAINTAINS IT'S HIGH TENSILE STRENGTH UP TO 700°F ( 380°C), 50% HIGHER THAN A CONVENTIONAL CAST PISTON. THIS HIGH TEMPERATURE RESISTANCE SIGNIFICANTLY IMPROVES FATIGUE STRENGTH AND IMPACT TOUGHNESS, WHICH MEANS THAT WE WILL KEEP YOU RIDING LONGER AND HARDER THAN THE COMPETITION.
A machined smooth piston crown should reflect combustion heat while reducing carbon buildup and protecting the top of the piston. Some tests have shown that a machined smooth head can in crease HP and fuel economy by up to 6%.
