Rebuilding your Ski-Doo 780 engine? This SPI 3 Piston Kit has everything you need. It's specifically for 1993-1996 Ski-Doo Formula Mach Z 780 and Mach Z 780 LT models. The kit includes three pistons, ring sets, wrist pins, and circlips—all made to OEM specifications, so they're a direct replacement and interchangeable with your original parts. These pistons are for a .020 over bore size, measuring 70.00mm. They feature a T-Moly (Teflon-Molybdenum) coating that reduces friction, resists seizure, and improves durability. SPI pistons are engineered for great heat transfer too. They're made in Taiwan with solid quality. If you're doing a top-end rebuild, this kit gives you reliable parts to get your sled running strong again. Always double-check your model and year for fit. Get ready to hit the snow with renewed power!
