SPI  Provides quality aftermarket Snowmobile parts and accessories that deliver on use and performance.

Because we keep in close contact with our Dealer Network, You can be assured of the Functionality and Quality of SPI. Unlike other companies whose main goal is set on pricing, We never source our aftermarket products in such a way. Each SPI product is specially designed to work as well or better than that of the Original Equipment’s part it replaces. If we wouldn’t put it on our own machines, we wouldn’t put it on yours- That’s the SPI promise.

All SPI products are tested before shipment to maintain the high level of quality that snowmobilers worldwide demand and most of the factories we use are ISO certified.

PRODUCT SPECIFIC TESTING INCLUDES:

• Electrical testing reports.
• 100% testing on cylinders.
• 3D scanning and constant material analysis on pistons.
• QC procedures on every step of the piston manufacturing process.
