Genuine AL-KO IRS® System
AL-KO IRS Independent Rubber Suspension Axle
Upgrade your towing experience with the industry-benchmark AL-KO IRS Axle. Utilizing an advanced Independent Rubber Suspension system, this axle features three specially formulated rubber cords housed inside a hexagonal outer tube. By allowing each wheel to move independently, it dampens road shock, controls body roll, and delivers unmatched stability for caravans, boat trailers, and heavy commercial loads.
Key Features & Benefits
- Independent Wheel Movement: Each wheel reacts to road bumps independently, keeping your trailer stable and tracking perfectly without shifting the entire chassis.
- Hexagonal Inner & Outer Tubes: The unique hexagonal design provides a mechanical lock for the high-quality rubber elements, ensuring progressive spring characteristics.
- Built-In Shock Absorption: Delivers a highly dampening ride that eliminates the need for auxiliary hydraulic shock absorbers on standard highway routes.
- Zero Maintenance Design: Engineered with premium rubber elements that do not suffer from the friction wear or squeaks of traditional leaf springs, eliminating routine greasing.
- Enhanced Cargo & Caravan Protection: Soft, progressive suspension dampening reduces high-frequency vibrations, protecting your caravan interiors and fragile trailer cargo.
Frequently Asked Questions
What does “IRS” stand for and how does it work?
IRS stands for Independent Rubber Suspension. Unlike straight or beam axles with leaf springs, the AL-KO IRS utilizes compressed rubber cords inside a hexagonal axle body. When a wheel hits a bump, the suspension arm rotates and compresses these cords, absorbing the impact smoothly right at the wheel hub.
How do I determine the correct load capacity rating for my trailer?
AL-KO IRS axles are custom-engineered for specific Aggregate Trailer Mass (ATM) brackets. You will need to check the factory weight plates or build specifications of your trailer. Overloading an IRS axle beyond its rating can over-compress the rubber elements, lowering your ride height and stiffening the ride.
Are these axles custom-made to a specific hub-to-hub width?
Yes. Genuine AL-KO IRS axles are typically manufactured to specific dimensions based on your trailer chassis width and required hub-to-hub (face-to-face) track measurement. Please cross-reference our measurement guide or contact our engineering desk before purchasing.
