Description
4244 701 1806 STIHL Backplate – Genuine OEM Fan Housing Support Plate
The STIHL Backplate (4244 701 1806) is a genuine OEM structural component designed for select STIHL backpack blowers, including the BR 350, BR 430, BR 450, and BR 450 C-EF models. This backplate is part of the fan housing and shroud assembly, providing critical support and alignment for the blower’s engine cooling and airflow system.
The backplate helps secure the fan housing components and ensures proper airflow routing through the blower system. Over time, backplates may crack, warp, or become damaged due to vibration, impact, heat exposure, or heavy commercial use. A damaged backplate can result in misaligned fan housing parts, airflow disruption, increased vibration, or reduced blower efficiency.
Replacing the backplate with the correct genuine STIHL OEM part restores proper housing integrity, correct component alignment, and reliable blower operation without replacing the entire fan housing assembly.
Manufactured to STIHL factory specifications, this OEM backplate ensures precise fitment, durable construction, and long-term performance under demanding operating conditions.
