AL-KO 2004/3004 Stabiliser Shim Kit – AKS Friction Pad Spacers

The AL-KO 2004/3004 Stabiliser Shim Kit is a genuine spare part designed for AL-KO AKS 2004 and AKS 3004 caravan stabiliser couplings — two of the most widely fitted stabilisers on UK tourers. AKS stabilisers use friction pads pressed against the towball to reduce snaking and improve towing stability, and this shim kit allows you to fine-tune the spacing between friction pads for optimal performance and consistent engagement.

Shim washers are often needed when replacing worn friction pads or adjusting the stabiliser to modern towball or pad tolerances. They help ensure that the friction pads make correct contact with the towball without binding or excessive looseness.

🔑 Key Features & Benefits

• ✔️ Genuine AL-KO Shims: Precision metal shim washers made to match AL-KO tolerances.

• ✔️ Designed for AKS 2004/3004: Suitable for the popular caravan stabiliser models (AKS 2004 and AKS 3004).

• ✔️ Improves Stabiliser Contact: Used to space friction pads correctly, ensuring effective stabiliser action and even wear.

• ✔️ Easy to Install: Simple shim washers that slot between the friction pad assembly and mounting surface.

• ✔️ Extends Component Life: Helps eliminate excessive play or binding in the stabiliser, reducing premature wear and noise.

📦 What’s Included

• 5 × 3 mm shims — fine adjustment spacers

• 5 × 5 mm shims — larger spacers for bigger adjustments

These shims provide flexibility to fine-tune your stabiliser pad spacing depending on wear and towball differences.

🔧 Why Shims Matter

The shim washers supplied in this kit are small but essential when servicing your stabiliser friction pads. As friction pads wear down over time, spacing between the pads and the towball changes, which can reduce the amount of friction force exerted — leading to less effective snaking suppression and increased vibration. Adding or removing shims lets you restore the correct pad-to-towball engagement and maintain optimum towing performance.

Tips for Use

• When installing friction pads, always clean surfaces and remove contaminants to ensure proper grip.

• Adjust shims gradually — test stabiliser feel after adding or removing a shim to find the best spacing.

• If friction pads are significantly worn, consider replacing pads before shimming.
