The Ronstan RF149 Steering Cable Tension Spring (115mm) is a critical component for maintaining consistent tension and smooth operation in marine cable steering systems. Designed for use on yachts, trailer boats, and small powerboats, it helps ensure responsive and reliable steering performance.

This spring works by absorbing shock loads and maintaining constant cable tension, reducing strain on steering components and preventing slack or uneven steering feel.

Manufactured from marine-grade stainless steel, the RF149 is highly resistant to corrosion and fatigue, making it ideal for long-term use in harsh saltwater environments.

With its 115mm length, it provides an optimal balance between flexibility and strength, making it suitable for both new installations and replacement in existing steering systems.

Why Choose the Ronstan RF149? 

For New Zealand boat owners, reliable steering is critical for safety and control, especially in coastal and offshore conditions. Cable steering systems can experience shock loads, vibration, and stretch, which over time can lead to poor responsiveness or component wear.

The RF149 helps solve these issues by:

• Maintaining consistent cable tension
• Reducing sudden load spikes
• Extending the life of steering cables and pulleys

It’s a simple, cost-effective upgrade that significantly improves the feel, reliability, and longevity of your steering system.

When You Need a Steering Cable Spring

• Steering feels loose or inconsistent
• Cable system shows wear or slack
• Installing or upgrading a mechanical steering system
• Boats without hydraulic steering (common on smaller vessels)
