Description
4237 791 3101 STIHL Spring – Genuine OEM Handle Frame Part
The STIHL Spring (4237 791 3101) is a genuine OEM component designed for use within the handle frame and fuel tank assembly of select STIHL professional hedge trimmers. This spring supports proper tension and positioning of internal handle or fuel system components, helping maintain reliable operation and structural stability.
Over time, springs can weaken, stretch, corrode, or lose tension due to vibration, repeated use, or exposure to fuel and environmental conditions. A worn or damaged spring may cause improper handle function, loose component positioning, or inconsistent control feel. Replacing it with the correct OEM part restores proper tension and factory performance without replacing the entire handle assembly.
Manufactured to STIHL factory specifications, this genuine spring ensures correct fitment, reliable tension, and long-term durability under professional operating conditions.
