Haltech H-2225 Extension Stabilizer for OLDER STYLE Alcoa 22.5" Wheels [EXTENSION NOT INCLUDED]

Proper air pressure is the most important factor in lengthening tire life. On dual wheel assemblies, the inner dual is many times overlooked or improperly serviced. The Alcoa Stabilizer allows access to the inner dual tire valve and properly positions and supports the extension for servicing. The stabilizer reduces the road vibration on the extension and practically eliminates valve stem breakage caused by vibration.
