Ingersoll Axles has introduced a 30-degree disc brake self-steering axle. The new SSA has a forward facing tie-rod design that allows turn angles up to 30 degrees for disc brake axles.

It is offered with Haldex, Wabco, and Bendix disc brake packages.

The new 30° design is optimized to work with the Ingersoll Suspension System, and is available in all track lengths, as well as an inverted drop center version.
