Polaris Ranger & Sportsman 700 Complete Bottom End Rebuild Kit

Bottom-end failures don’t always mean the entire engine needs to be replaced. If your cylinder, piston, camshaft, and valve train are still within specification, this kit gives you the components needed to rebuild the rotating assembly without purchasing unnecessary top-end parts.

Replacing worn crankshaft and bottom-end components during one teardown helps restore proper bearing clearances, reduce vibration, and provide a solid foundation for the rest of the engine.

What This Kit Includes

• Oil Seal Set
• Water Pump Seal
• Crankshaft
• Counter Balance Kit
• Complete Gasket Kit
• (2) Main Bearings

When Is This the Right Kit?

Choose this kit when the lower end of the engine has suffered bearing or crankshaft damage, but the cylinder, piston, camshaft, lifters, and valves can be reused after inspection. Replacing only the worn components helps keep rebuild costs under control while restoring proper engine operation.

• Replacement crankshaft included.
• Main bearings and complete gasket set.
• Counter balance components and seals.
• Built for complete lower-end engine repairs.
