Master Engine Rebuild Kit for Polaris Sportsman & Scrambler 1000 (2015–2022)

If your Polaris Sportsman 1000 engine is worn out, knocking, or ready for a full rebuild, this master engine rebuild kit gives you the parts to do it right from the bottom end up. This isn’t a partial kit. It covers both top and bottom end components so you can rebuild the entire engine without cutting corners.

You get a heavy-duty crankshaft, forged connecting rods, upgraded moly pistons, and a full valve set, along with all bearings, seals, and gaskets needed to complete the job. When it says master, it means you’re rebuilding the engine—not patching it.

• Main bearings
• Counterbalance bearings
• Complete gasket set
• High-temp upgraded valve stem seals
