Elevate trailer performance with the Double Eye Rocker Type - 3500kg, a purpose-built suspension pair designed for a smoother, more controlled ride. At 50mm wide, these rockers sit securely on angle iron frames, making them a practical upgrade for trailers where a premium level of stability and comfort is essential—even under heavy loads.

How it works is simple but highly effective. Trojan Rocker Tandem Suspensions distribute weight evenly across all four wheels by mounting the springs on a rocker bar that pivots on a central hanger. That smart motion dampens road shocks and reduces sway, delivering a noticeably steadier journey whether you’re transporting livestock, equipment, or a loaded trailer across uneven terrain. The Double Eye configuration (two eyelets per spring) enhances stability and helps maintain consistent tire contact, contributing to shorter stopping distances and better handling in demanding conditions.

Why this model stands out

• High-capacity, dual-eye design: 3500kg capacity per pair provides robust performance for heavy trailers, including horse floats and larger utility haulers.
• 50mm width for versatile mounting: A compact footprint that fits a broad range of trailer chassis while delivering a noticeable ride improvement.
• Mounting options to fit your build: Available as a kit that can be welded directly to the trailer chassis or supplied assembled, fitted to an angle iron frame. The kit can be chosen as unmounted bare steel or mounted and assembled with a galvanised frame for added corrosion resistance.
• Frame compatibility without constraints: The kit does not include the frame itself, offering flexibility so you can pair these rockers with your existing trailer structure or a purpose-built frame.
• Proven ride quality on demanding trailers: Specifically recommended for trailers requiring a superior ride, including horse floats and other heavy-duty applications where steady handling matters.

Practical tips for your install and use

• Choose the mounting option based on your frame availability: a bare steel kit for direct welding, or a galvanised frame version for enhanced corrosion resistance in challenging environments.
• Ensure your frame design accommodates the 50mm width of the rocker pair and aligns with the central hanger pivot points for optimal load distribution.
• Keep in mind that the kit does not include axle U-bolts or plates; you’ll need to source these components to suit your trailer’s axle setup.
• For horse floats or livestock trailers, the improved ride translates to reduced jolt transfer to the animal, contributing to safer, calmer transport.
