All Knott Coupling Parts
Knott coupling parts are essential for maintaining the safety, performance and reliability of Knott-Avonride trailer couplings. Our range of trailer coupling spare parts includes genuine replacement components designed specifically for Knott overrun couplings used on many braked trailers.
Within this category you’ll find key trailer coupling replacement parts such as bellows (gaiters), coupling dampers, drawtubes, handbrake lever assemblies and locking mechanisms. These overrun coupling parts play a critical role in safe braking, smooth towing and protecting the internal components of your trailer coupling system.
Using genuine Knott replacement parts helps ensure full compatibility with Knott-Avonride couplings and maintains the original performance of your trailer towing equipment. Replacing worn trailer coupling components such as dampers, bellows or drawtubes can help extend the life of your coupling while keeping your trailer safe and roadworthy.
Regular inspection and maintenance of your trailer towing parts helps prevent failure, improve braking performance and are crucial for optimal functionality and safety.
Knott Coupling Parts Guide
At MAXA Group, we stock parts to suit Knott-Avonride trailer couplings, one of the most widely used overrun coupling systems on braked trailers across the UK. Keeping the right spares on hand helps shorten workshop time and keeps trailers safe, compliant and ready for use.
Within this range you'll find the components most often replaced on Knott couplings: bellows (gaiters), dampers, drawtubes, handbrake lever assemblies, locking heads and jockey wheel locking handles. Replacing a worn damper, bellows or drawtube can restore smooth coupling operation without the cost of a full unit.
Pair Knott parts with our breakaway cables & universal coupling spares range for the safety-critical secondary connection, and see our Knott brakes range if you're carrying out wider maintenance on the same trailer. If you run a mixed fleet, we also stock AL-KO coupling parts and Indespension coupling parts. All components are held in UK stock for fast delivery.
Knott Coupling Parts FAQs
What parts most commonly need replacing on a Knott coupling?
Bellows, dampers and drawtubes are among the most frequently replaced parts, along with handbrake lever assemblies and locking heads on higher-mileage trailers.
Do you supply parts to suit Knott-Avonride couplings?
Yes, we stock a wide range of parts to suit Knott and Knott-Avonride couplings. Confirm your coupling's weight rating and fitting size before ordering.
What does a coupling damper do?
A damper helps control and smooth the coupling's movement during towing and braking. A worn or leaking damper can affect how the coupling responds under load.
Can individual Knott coupling parts be replaced separately?
Yes, in most cases. Bellows, dampers, drawtubes and locking heads can typically be replaced individually rather than fitting a complete new coupling.
What is a coupling locking head?
The locking head is the part of the coupling that secures over the vehicle's tow ball. It should operate smoothly and lock securely before towing.
How often should Knott couplings be inspected?
Couplings should be checked before every tow and as part of regular fleet maintenance, looking for wear on the bellows, damper, drawtube and locking mechanism.
