The Eye to Slipper combination for 2200kg, 45mm wide (Pair) is Trojan’s proven approach to even load distribution on challenging road surfaces. With the eye end of the springs bonded to the centre rocker, this suspension delivers extended rocker movement and consistent stability across all four trailer wheels—precisely what commercial fleets and off-road trailers demand.

Why this design matters

• Uniform load sharing across all four wheels helps reduce tire wear and axle stress, improving overall trailer longevity in demanding conditions.
• Maximum rocker movement is achieved by mounting the eye ends to the centre rocker, allowing the suspension to respond adaptively to uneven terrain, potholes, and off-road obstacles.
• Direct-to-chassis fitment simplifies installation and alignment, making replacement and maintenance more straightforward for fleets and workshops.
• Robust leaf setup with 3 leaves of 45 x 8mm provides solid support for mid-weight applications, while keeping a compact 45mm width profile for compatibility with a range of trailer frames.
• Part of the Trojan Rocker Tandem family designed to work as a matched system when paired with other components in the lineup, ensuring consistent performance across configurations.

Key features

• Capacity per Pair: 2200 kg
• Leaves: 3 leaves, 45 x 8 mm
• Fitment: Direct to chassis
• Eye end connected to centre rocker for enhanced movement
• Includes pair (two suspensions) for balanced four-wheel support
• Does not include axle U-bolts or plates

Ideal applications

• Commercial trailers that regularly travel on rough roads or construction sites
• Off-road caravans and expedition trailers where terrain variability is high
• Agricultural trailers operating across uneven fields and rural routes
• Heavy-duty light-truck trailers requiring dependable load distribution

What sets it apart

Unlike standard leaf-spring configurations, the Eye to Slipper design uses a rocker bar centered on a hanger to translate wheel movement more evenly across the tandem setup. This results in a smoother ride for cargo, less chassis flex, and a more predictable towing experience in challenging environments. If you’re upgrading a trailer that frequently encounters rough surfaces or heavy payloads, this pairing offers a tangible upgrade in stability and longevity without overhauling your entire suspension system.

Practical tips for installation and use

• Verify chassis compatibility before mounting; not all frames accept direct-to-chassis suspensions without modification.
• Check that the central hanger and rocker pivot are clean and lubricated to maximize the available rocker movement.
• Pair with appropriate axle U-bolts and plates as required by your trailer build to ensure secure integration.
• Regularly inspect the leaves and pivots for signs of wear or corrosion, especially in off-road or harsh environments.
