FAQs
What weight range is this damper suitable for?
This Alko 161 damper is suitable for braked trailer and caravan hitches with a capacity ranging from 950kg to 1600kg.
Which specific Alko hitch models is this damper compatible with?
It is specifically designed for Alko braked trailer and caravan hitches, model number 161, manufactured before 1998.
Can I use this damper on a newer Alko hitch model?
No, this damper is only compatible with the older Alko 161 model (pre-1998). Newer models have different specifications and require different parts.
What are the physical dimensions of the damper?
The total length of the damper is 350mm, the body length is 210mm, and the body diameter is 25mm.
How do I know if my damper needs replacing?
Signs include harsh or jerky trailer braking, the trailer brakes not applying correctly, or any visible leaks from the damper unit. If you notice any changes in braking performance, it's wise to inspect it.
Is this a difficult part to install?
Installation requires disassembling the trailer hitch. While possible for DIY enthusiasts with the right tools and guidance, it's recommended to have it done by a qualified mechanic if you are unsure.
Does the damper require maintenance after installation?
The damper itself is a sealed unit and typically does not require maintenance. However, keeping the overall hitch mechanism clean and ensuring the brake rod moves freely is important for optimal performance.
Troubleshooting
Trailer brakes not engaging smoothly or at all
Check if the damper is properly installed and the hitch mechanism is moving freely. Ensure the brake rod is correctly connected and not binding. If the damper shows signs of leakage or damage, it likely needs replacement.
Harsh or jerky braking from the trailer
This can indicate a faulty or seized damper. The damper may be restricting movement too much or has lost its damping properties. Replacement is usually required.
Damper appears to be leaking fluid
A visible leak signifies that the internal seals have failed. The damper has lost its internal pressure and damping fluid, and must be replaced immediately.
Difficulty in moving the hitch override lever
Ensure the area around the hitch and the brake rod is clean and free of obstructions. If the hitch is still stiff, the damper may be faulty or the internal mechanism requires lubrication (refer to Alko documentation).

Setup, Compatibility & Care
Compatibility:
This damper is specifically designed as a replacement part for Alko braked trailer and caravan hitches, model number 161, manufactured before 1998. It is rated for hitches with a capacity between 950kg and 1600kg. It is essential to confirm your existing hitch is an Alko 161 model from the specified period before purchase.
Setup (Installation):
Installation of a trailer hitch damper typically requires mechanical knowledge and appropriate tools. The damper is usually housed within the main body of the hitch assembly. The process generally involves:
- Disconnecting the hitch from the trailer chassis (or at least ensuring the trailer is safely supported).
- Disassembling the hitch to access the damper unit. This often involves removing locking pins and sliding out components.
- Replacing the old damper with the new Alko 161 unit, ensuring it is oriented correctly.
- Reassembling the hitch components in reverse order.
- Testing the hitch mechanism thoroughly before reconnecting to the trailer and using it on the road.
*Note: It is highly recommended to consult the official Alko service manual for your specific hitch model or seek professional assistance if you are not experienced with trailer hitch maintenance.*
Care:
The damper itself is a sealed unit and generally requires no specific user maintenance. However, the overall hitch assembly should be kept clean and free from excessive dirt and debris. Periodically inspect the hitch for any signs of damage, corrosion, or leaks, which could indicate issues with the damper or other components. Ensure all bolts and retaining pins are secure.
Regular checks include:
- Visual inspection for damage or leaks.
- Ensuring the hitch mechanism moves freely (when the damper is removed or the system is unpressurised).
- Checking that the brake rod operates smoothly.
