This heavy-duty 65mm Rocker Roller Centre Arm is a high-strength replacement component specifically engineered for 6-tonne (6t) trailer and caravan suspension systems. Built to withstand the rigours of heavy hauling, this arm ensures smooth load distribution across multi-axle setups.
Product Overview
Designed as a direct replacement for worn or damaged centre rockers, this arm is the pivot point of your suspension. It allows the rocker roller springs to articulate independently, maintaining tyre contact with the road and reducing stress on your trailer’s chassis.
Key Features
- Heavy-Duty Construction: Manufactured from high-grade cast iron or forged steel to handle the extreme vertical and lateral loads of 6-tonne GVM trailers.
- Precision Fit: Sized specifically for 65mm wide rocker roller springs, providing a snug, secure fit that prevents excessive side-play.
- Enhanced Durability: Finished with a corrosion-resistant coating (galvanised or industrial paint) to protect against road salt, moisture, and debris.
- Ready for Greaseable Hardware: Pre-drilled to accommodate standard high-tensile shackle pins, enabling easy maintenance and long-term lubrication.
Technical Specifications
- Spring Width Compatibility: 65mm
- Suspension Type: Rocker Roller (Multi-axle)
- Load Rating: Suited for 6,000kg (6t) systems
- Centre Pin Hole: Designed for 1″ (approx. 25.4mm) greaseable shackle bolts
- Finish: Durable Black or Galvanised
Why Replace Your Centre Arm?
A worn rocker arm can lead to “clunking” sounds, uneven tyre wear, and poor tracking. By replacing a thinned or ovalised centre arm, you restore the geometry of your suspension, ensuring your trailer handles safely under full load.
