Starting Line Exhaust Valve Spring
- Polaris exhaust valves open with cylinder pressure
- As you go up in elevation cylinder pressures are reduced causing exhaust valves to open later than they should or in some cases not at all
- This can cause poor and inconsistent top end horsepower
- Changing to lighter exhaust valve springs allows the exhaust valves to open at the proper time maintaining proper top end horsepower and running consistency
- Sold individually
