Genuine AL-KO Coupling Trigger Replacement Kit (Part No. 610909)
The AL-KO Coupling Trigger Replacement Kit (Part No. 610909) is an essential maintenance set that restores the locking function of your trailer coupling. This genuine AL-KO International Pty Ltd kit provides a cost-effective way to replace weathered or damaged components without replacing the entire coupling body.
Product Overview
This comprehensive kit is engineered to fit a wide variety of 50mm ball couplings, including Electric, Override (Braked), and Snap-On (Fixed) models. Over years of use, the internal trigger spring can weaken from exposure, or the roll pin may wear, leading to difficult engagement or unsafe latching. Replacing these parts ensures a crisp, secure “click” every time you hitch up.
Key Features
- Complete Replacement Set: Includes a high-strength trigger, a tension-matched spring, and a precision roll pin for a total refresh of your latching mechanism.
- Universal Compatibility: Specifically designed for AL-KO International Pty Ltd snap-on and plunger-style couplings commonly used on caravans, boat trailers, and utility trailers.
- Durable Materials: The heavy-duty component layout features a roll pin made from high-strength spring steel with a protective zinc-plated finish for superior corrosion resistance in marine and outdoor environments.
- Safety Assurance: Maintains strict compliance with Australian Design Rules (ADR) by ensuring the secondary locking mechanism operates exactly as intended.

Frequently Asked Questions
- How do I know if this trigger fits my trailer? This kit only fits genuine AL-KO couplings. Check for the stamped AL-KO logo on your hitch body before you buy.
- Does the kit include the main mounting pin? Yes. The pack comes with a new spring, roll pin, and trigger lever for a full repair.
- Can I install this part myself? You can fit it with basic hand tools. However, you must test the locking mechanism thoroughly before towing.
Do’s and Don’ts
- DO apply a small amount of heavy-duty grease to the pivot pin during assembly.
- DO block the trailer wheels safely before starting any repair work.
- DO inspect the main hitch ball socket for excessive wear while the trigger is off.
- DON’T reuse the old roll pin because old pins lose their tension and can fail.
- DON’T use a damaged hitch if the new trigger fails to click into place tightly.
- DON’T over-tighten the components or force the trigger if it feels jammed.
