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 designed to restore the locking functionality 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.
