Aircraft spacers are used to maintain proper distance, alignment, and load distribution between components in assemblies throughout vintage and WWII aircraft. These simple but essential parts are found in structural joints, control systems, and mounting installations.

Our selection includes spacers designed to match original specifications, with attention to inner and outer diameter, length, and material. Proper spacer selection ensures correct fitment and prevents issues such as misalignment, binding, or uneven load distribution.

We support identification using dimensional data and known aircraft applications. For restoration and maintenance, correctly sized spacers help preserve system geometry and ensure reliable operation across a wide range of applications.
