Product Details

The Wiseco SK1337 is a Pro-Lite standard bore piston kit engineered for Polaris 440 2-stroke snowmobile engines. With a standard bore diameter of 66.00mm, this kit delivers the precision fit and durability that Wiseco is known for across decades of powersports performance.

Wiseco's Pro-Lite forged 2-stroke pistons are crafted from high silicon, low expansion aluminum alloy, delivering superior strength, reduced weight, improved heat transfer, and extended service life compared to OEM cast alternatives. Each kit is machined to tight tolerances and proven at all levels of riding.

Kit Includes:

  • Forged Pro-Lite piston
  • High-performance ring set
  • Alloy wrist pin
  • 2 circlips
  • Gasket set

Note: Top end bearing is not included. Kit is sold as a standard bore (66.00mm) application. Verify your existing bore size before ordering to confirm standard or oversize fitment is required.

Wiseco piston kits are the trusted choice for snowmobile engine rebuilds, delivering the reliability and performance needed to get back on the trail with confidence.
