Integrated Trailer Suspension System

Hendrickson Trailer Suspension Systems' lighter weight Intraax AAT integrated trailer suspension system features the company’s Large Diameter Axle (LDA). The switch to LDA increases the outer diameter from today’s 5” axle to 5-3/4”, while slightly reducing the axle wall thickness. This reduction, combined with the increased diameter, creates a more efficient use of material, increasing axle strength while reducing weight. The new AAT LDA delivers as much as a 15% increase in bending and torsional stiffness compared to its 5-inch counterpart.
