Sidewinder Positive Rear Steer System

Anchor 1

The Muldoon Sidewinder Positive Rear Steer System is an award-winning, fully patented innovation designed to dramatically enhance manoeuvrability and reduce tyre wear on semi-trailers.

Available in both mechanical and hydraulic configurations, the system is adaptable across a wide range of trailer applications — enabling access to previously unreachable delivery locations, even those that challenge conventional steer systems or require smaller-capacity vehicles.

How It Works

At the core of the Sidewinder system is a unique cam and roller mechanism, driven directly from the fifth wheel coupling — a feature that sets it apart from all competitor systems.

Hydraulic System

Controlled via two hydraulic rams at the front that activate two rear-mounted rams
Powered by a self-pressurised system incorporating an accumulator and patented manifold valve
Delivers a smooth, responsive steering action
Automatically re-aligns in the event of slippage from impact (kerbs, potholes, etc.)

Mechanical System

Operates using steering rods instead of hydraulics
Retains the same cam and roller actuation for consistent response and control

Key Features

Self-aligning rear steer
Cam and roller module for instant response
Oil replenishment system to maintain pressure
Faster reaction to tractor unit movement than conventional systems
Twin galvanised piping for safety and durability
Lightweight design with minimal maintenance
Long-life rams with stainless steel/chrome rods and double seals
Oil pressure gauge and warning light included

Why Sidewinder Outperforms Competitors

Unlike conventional rear steer systems that only reach full effectiveness when the tractor reaches a 90° angle to the trailer, the Sidewinder system achieves full steer capacity at just 40°. This ensures maximum manoeuvrability much earlier in the turning process — providing continuous steering benefit throughout the turn.

This rapid response is made possible by the exclusive cam and roller design, giving the system a significant edge in both tight spaces and real-world driving scenarios.

More Control, Better Layout

The enhanced responsiveness allows the front axles to be positioned further forward, shortening the trailer’s effective pivot point. This means:

Tighter turning circles
Improved weight distribution
Enhanced stability and traction

The system works seamlessly in both forward and reverse, providing a constant benefit — unlike lift axles, sliding bogies, or self-tracking alternatives.

Benefits at a Glance
