AL-KO Independent Rubber Suspension (IRS) Axle represents the benchmark in fully independent trailer suspension. The independent suspension and enhanced ride quality is achieved through AL-KO’s unique hexagonal rubber suspension system. Made here in Australia the IRS axle is manufactured to exact engineering standards and is fully tested using the sophisticated vehicle alignment technology. Quality is important and, as such, each individual IRS axle is manufactured to exact engineering standards. AL-KO also uses the most advanced technology to test each axle for toe-in and camber, as well as load rated deflection
