4243 710 7107 STIHL Drive Tube Assembly Ø 25.4 x 1070 mm – Genuine OEM Shaft Housing Part
The STIHL Drive Tube Assembly Ø 25.4 x 1070 mm (4243 710 7107) is a genuine OEM shaft housing component designed for use on select STIHL long-reach hedge trimmers. This drive tube assembly forms the main structural tube that supports the internal drive shaft, connecting the engine powerhead to the gear head and cutter bar system.
Over time, drive tube assemblies may become bent, damaged, or worn due to heavy-duty professional use, impact during transport, or excessive vibration. A damaged drive tube can lead to misalignment, driveline wear, reduced cutting performance, or unsafe operation. Replacing it with the correct OEM assembly restores factory driveline alignment and structural integrity without modifying the original unit design.
Manufactured to STIHL factory specifications, this genuine drive tube assembly ensures correct fitment, durability, and long-term reliability under demanding landscaping and commercial trimming conditions.
