Polaris 700/800 Exhaust Valve Kit for RZR, Ranger & Sportsman Models

Restore proper exhaust flow and support cylinder head performance with this exhaust valve kit for applicable Polaris 700 and 800 engines. Designed for 2003–2017 RZR, Ranger, and Sportsman models, this kit includes replacement exhaust valves commonly serviced during top-end repairs and valve train maintenance.

Because exhaust valves operate under high heat and repeated engine cycles, replacing worn valves during service helps support compression, engine efficiency, and long-term reliability.

• (2) Exhaust valves

Fitment

• Polaris RZR 700/800
• Polaris Ranger 700/800

Why Replace Exhaust Valves?

Exhaust valves live in one of the hottest areas of the engine. Over time, heat cycles and normal wear can reduce sealing performance and airflow. As a result, engines may develop compression loss, rough running, hard starting, or reduced power.

Replacing worn exhaust valves during top-end service helps restore sealing and supports more dependable engine operation.

Completing a Full Valve Refresh?

If you’re rebuilding the cylinder head, pair this kit with our Polaris 700/800 Intake Valve Kit to service both intake and exhaust sides during the same rebuild.

If your project expands into a larger repair, review our Engine Rebuild Kit Guide to compare available rebuild options and kit levels.
