Bottom End Refresh Kit for Polaris Sportsman 570 (2017–2023)

Over time, internal wear components in the lower portion of your engine begin to show signs of fatigue. This Polaris Sportsman 570 bottom-end refresh kit provides the essential components commonly replaced during bottom-end service.

Rather than sourcing individual parts, this refresh kit bundles key sealing and timing components used during preventative maintenance or partial engine service. As a result, it helps restore reliability without requiring a full engine rebuild.

What’s Included in This Bottom End Refresh Kit

• Oil seal kit
• Timing chain
• Oil pump chain
• Ball bearing
• Complete gasket kit

Why Perform a Bottom End Refresh?

Chains, seals, and bearings experience constant stress during engine operation. Over time these components can stretch, wear, or lose sealing ability. Replacing them during service helps maintain proper timing, oil pressure, and internal sealing.

This kit is backed by our 1-year parts warranty for added confidence.

Installation Support
