Description
4243 710 7111 STIHL Drive Tube Assembly Ø 25.4 x 752 mm – Genuine OEM Shaft Housing Part
The STIHL Drive Tube Assembly Ø 25.4 x 752 mm (4243 710 7111) is a genuine OEM shaft housing component designed for select STIHL long-reach hedge trimmers. This drive tube assembly provides the structural tube that supports the internal drive shaft, ensuring smooth power transfer from the engine to the gear head and cutter bar system.
Over time, drive tube assemblies can become bent, cracked, or worn due to heavy-duty trimming use, transport damage, or excessive vibration. A damaged drive tube may cause driveline misalignment, increased vibration, reduced cutting performance, or premature wear on internal components. Replacing it with the correct OEM assembly restores factory alignment and operational reliability without altering the original equipment design.
Manufactured to STIHL factory specifications, this genuine drive tube assembly ensures correct fitment, durability, and long-term performance under professional landscaping conditions.
