Steel Bushing for Aeon Springs

Steel Bushings

We cut every Aeon® metal bushing on our state-of-the-art CNC machine.

The Test Of Time

We found it laying on the side of the road just outside our manufacturing facility in Whitby,
Ontario, Canada. The truck frame is completely rusted but the rubber spring us still good! We’ve been saying it for 40 years, and we still think it’s true:
“Aeon® Springs are stronger than steel, more reliable than air.”
