Overslung and Underslung of Trailer Axle

    Posted: 2013-10-31
 

When buying a mechanical suspension or air suspension containing a trailer axle, you need to tell the supplier which type of the products you want: Overslung or Underslung.

 

Underslung mounts have the spring mounted under the trailer axle, while overslung mounts have the spring mounted above the axle. It is up to your preference, it wouldn’t make a huge difference in strength though. The overslung mounts would give you more clearance between the axle and the chassis than the underslung mounts, this is important when riding on a bumpy road.
