Exhaust Valve Spring Kit for KTM 250/350 SX-F EXC-F 2015-2026 - 79036028044

This genuine OEM Exhaust Valve Spring Kit is essential for maintaining the precise timing and performance of your engine's valve train. It ensures the exhaust valves close securely against the valve seats, preventing power loss and protecting internal components from high-heat damage. As a critical component of the cylinder head assembly, it provides the necessary tension for reliable operation at high RPMs.

This kit is compatible with an extensive range of 250cc and 350cc four-stroke models. It fits KTM 250 and 350 SX-F, XC-F, and EXC-F models from 2015 to 2026, including Six Days and Factory Editions. It is also designed for Husqvarna FC/FE 250 and 350 models (2016-2026) and GasGas EC, MC, and EX 250F/350F models (2021-2026), as well as the KTM Freeride 250 F and RC4 R.

The kit includes the high-tension valve spring, the upper retainer, and the lower washer seat as shown in the technical diagram. Using original equipment parts ensures that the spring rate and material tolerances perfectly match factory specifications, which is vital for preventing valve float and ensuring long-term engine durability.

Replacing valve springs during a top-end rebuild or scheduled maintenance is highly recommended to prevent fatigue-related failures. Proper installation ensures your motorcycle maintains its peak horsepower and throttle response throughout the powerband.
