Stock Update - 13th Jun 2021

Sorry, this item is not in our warehouse.
The demand for this product is normally very low so we only get these in as needed.
If you place an order, we will get it with our weekly supplier delivery.


The Alko AKS3004 Stabiliser is a specific coupling designed to reduce trailer sway. This 50mm ball type fixed coupling is designed to be used on a Caravan or trailer up to 2500 kg total loaded mass and with a maximum tow ball weight of 250 kg.

This unique product incorporates a clamping system that grips the sides of a specially designed 50mm towball (AKS2000) and resists movement of the trailer. This action slows down any tendency for the trailer to sway or veer from a straight condition. This is particularly beneficial when large trailers such as caravans are buffeted by side winds or by a passing truck and trailer combination.

This stabiliser is a complete coupling that bolts onto the Caravan/Trailer A-frame.

It must be used with ALKO's anti rotating tow-ball and retention plate that prevents the towball rotating on the towbar.
