Product Details

The Namura Technologies NA-50024-2K is a complete top end rebuild kit designed for Polaris powersports engines requiring a +.5mm oversize bore. This comprehensive kit provides everything needed for a professional-quality top end restoration.

Complete Kit Includes:

  • Oversize piston (+.5mm bore)
  • Piston rings
  • Wrist pin and circlips
  • Top end bearing
  • Complete gasket set

Premium Piston Features:

  • MOS2 Coated Skirts: Teflon/Molybdenum coating applied through a rolled-on process creates a bond 10 times stronger than spray-on coatings, providing superior heat transfer, reduced friction, and protection against cold seizures
  • Machined Smooth Heads: Precision-machined piston heads reflect combustion heat and minimize carbon buildup, potentially increasing horsepower and fuel economy by up to 6%
  • Anodized Domes: Hard anodizing treatment increases heat resistance and structural integrity, making the piston 75% stronger than non-anodized alternatives
  • Hypereutectic Construction: Advanced casting process with higher silicon content delivers reduced thermal expansion, enhanced wear resistance, and superior performance at elevated cylinder temperatures

This oversize kit is ideal for engines that have been bored out for rebuild purposes or performance applications. Namura Technologies pistons are manufactured to OEM specifications with premium enhancements for improved durability and performance.

Second time customer of Autoplicity: Ordered Husky Liners Weatherbeater Floor mats for a 2012 Toyota Tundra, Called in this morning to verify availability, call answered on second ring, great service placed the order immediately. Haven't even received the product yet but the service has been so outstanding had to let everyone know this company is for real. Best pricing online, wont buy products anywhere else.<br><br>Justin Myers

Easy checkout. Thanks.

A bit pricier than other sites, but if you have the item in stock and I don't have to wait a month to get it.

Good price, fast shipping. Will buy again
