Replacement Towbar Necks.
If you tow a trailer, caravan, bike rack or horsebox, your towbar is probably one of the hardest-working parts of your vehicle. But like any component, towbar parts can wear out over time, and the neck is no exception. Whether it’s due to rust, damage, or simply upgrading your setup, replacing your towbar neck might be a necessity. Here’s what you need to know.
What Is a Towbar Neck?
The towbar neck is the part of the towbar assembly that connects to your trailer or accessory. In the UK, there are typically two main types:
- Fixed flange necks – bolted directly onto the towbar plate, often used for heavier towing.
- Detachable swan necks – sleeker in design and can be removed when not in use.
Some vehicles also use a fixed swan neck towbar, which is always in place but more discreet than a flange setup.
Why Replace a Towbar Neck?
Towbar necks are subject to stress, corrosion and occasional knocks, especially in the UK’s often wet and salty road conditions. You might need a replacement if:
- The neck is showing signs of excessive rust or wear.
- You’ve had a minor rear-end bump and want to ensure it’s structurally sound.
- You’re changing the type of trailer or accessory and need a different style.
- You’ve lost a detachable neck (yes, it happens more than you’d think).
- The towbar neck has been stolen.
Can You Replace Just the Neck?
Yes – but it’s crucial to get the correct match. Not all necks are interchangeable, even within the same brand. The neck must be:
- Compatible with the towbar.
- Tested and approved (EC94/20 or newer UKCA marking).
- Installed correctly, ideally by a professional.
Where to Find Replacement Towbar Necks in the UK
There are several options:
- Towbar specialists: Companies like Brink and TowTrust all supply replacement parts. Many will need your towbar’s part number or vehicle make/model.
- Online retailers: Websites such as PF Jones, Towequipe and eBay can be a good source, but double-check compatibility.
- Local fitters: Many mobile towbar installers can supply and fit a replacement neck on-site.
How Much Does a Replacement Cost?
Prices vary depending on the make and model:
- Fixed flange necks: From £80 upwards, depending on the make and model.
- Detachable necks: £100–£300 depending on make and model.
Fitting costs are extra unless you’re confident with DIY installs (note: improper fitting can invalidate insurance or compromise safety).
How do I know which Towbar Neck I need?
The type approval label on your towbar will give you the towbar manufacturer and the towbar number; with this information, you can find the appropriate neck. Unfortunately, if the towbar is missing the type-approval label, of the label is unable to be read, then it is not possible to fit a new tow bar neck. (The type approval label is legally required to be readable.)
Safety and Legal Considerations
In the UK, towing gear must meet type approval regulations, especially for vehicles registered after 1998. Using an incorrect or damaged neck can:
- Lead to MOT failures.
- Invalidate your insurance.
- Possibility of prosecution and points on your licence
- Pose serious safety risks.
Always ensure your replacement is manufacturer-approved and professionally installed if unsure.
Final Thoughts
Your towbar neck might seem like a small part of the setup, but it’s vital to safe and legal towing. Whether you’re replacing a worn-out flange neck or upgrading to a removable system for a sleeker look, make sure you source the correct part — and don’t cut corners on quality.
If in doubt, speak to a local towbar specialist. A quick check now can save a major headache (and cost) down the line.
