The Arctic Cat Jag 340 snowmobile models from 1987 to 1990 were renowned for their power and performance, and upgrading the piston kit is an excellent way to enhance the engine's capabilities. This race-driven 89119 piston kit is specifically designed to deliver top-tier power, reliability, and durability for your Arctic Cat Jag 340 snowmobile.
The pistons in this kit are crafted from forged aluminum, ensuring superior strength and consistency. With a compression ratio of 11.5:1, these pistons maximize power output while maintaining efficient combustion. The piston skirts are engineered with a close-tolerance design, reducing friction and ensuring a snug fit within the cylinder walls for optimal engine performance.
The piston rings included in this kit are designed to minimize compression loss and oil consumption. The top rings are made from nitrided chrome molybdenum alloy, which provides excellent sealing properties and resists wear. The secondary rings are made from iron, ensuring a tight seal and preventing oil leakage.
The piston pins are manufactured from chrome molybdenum steel, providing the necessary strength and durability to withstand the rigors of high-performance snowmobile use. The piston pin bore is chrome-plated for added protection against wear and corrosion.
The piston kit also includes new piston pin bushings and wrist pin clips. The bushings are made from high-quality materials, ensuring a smooth and reliable fit for the piston pins. The wrist pin clips securely hold the wrist pins in place, providing added stability and preventing piston movement during operation.
In summary, this race-driven 89119 piston kit for the Arctic Cat Jag 340 snowmobile models from 1987 to 1990 is an excellent investment for those seeking to maximize power output, reliability, and durability. With forged aluminum pistons, nitrided chrome molybdenum top rings, iron secondary rings, chrome molybdenum steel piston pins, and high-quality piston pin bushings and wrist pin clips, this kit is designed to deliver superior performance and longevity for your Arctic Cat Jag 340 snowmobile.
