This piston kit comes with all the necessary hardware for installation, including new piston pins, clips, and wrist pin bushings. The pistons are also pre-gapped, which saves time and effort during installation.

The WiseCo MN/B3BR piston kit is a direct fit for 1989-1997 Polaris Classic engines, making it a convenient and hassle-free upgrade option. The pistons are also designed to work with both two-stroke and four-stroke engines, making this kit a versatile choice for Polaris Classic owners.
