Find horsebox parts suppliers for repair, service, refurbishment, conversion and production work across the UK, with international component manufacturers and distributors included where they can support British trade buyers. This specialist EquiGuild directory covers suppliers of mechanical, body, electrical and horse-area replacement parts for 3.5-tonne horseboxes, larger HGV horseboxes and horse trailers.

Whether you are a horsebox builder, repair workshop, dealership, fleet operator, retailer or professional rider maintaining transport, successful sourcing starts with proper identification. A ramp spring, brake shoe, roof vent or partition fitting may look straightforward, but vehicle make, build year, chassis arrangement, loading rating and original component manufacturer can all affect whether the part is suitable.

What horsebox parts suppliers can provide

Horsebox spares range from general vehicle-service items to specialist livestock-transport fittings. Some suppliers stock a broad catalogue; others concentrate on a particular chassis brand, trailer running gear, aluminium body system, ramp mechanism or conversion platform.

Running gear, towing and underbody components

This category includes axles, hubs, bearings, brake drums, brake shoes, brake cables, overrun couplings, dampers, drawbars, jockey wheels, prop stands, wheels, tyres, mudguards and breakaway cables. These are high-priority items because component specification affects roadworthiness, towing stability and serviceability. For a horse trailer, do not order on appearance alone: provide the trailer VIN or data plate details, axle and coupling make, dimensions, load rating, wheel fixing information and clear photographs where possible.

Buyers sourcing braking parts should distinguish between complete assemblies and consumables. A supplier may offer brake shoes, cables, backplates, drums or bearing kits, but compatibility can depend on brake size, axle family and hub arrangement. Where a repair changes more than one linked component, ask whether the quotation covers the complete required set rather than an isolated part.

Horsebox chassis and vehicle-service parts

Van-based horseboxes also require conventional commercial-vehicle parts: brakes, suspension components, steering parts, batteries, mirrors, cooling parts, filters, exhaust components and cab lighting. A specialist horsebox repairer may buy these from vehicle factors while sourcing the coachbuilt elements elsewhere. For 3.5-tonne conversions, state the base-vehicle make, model, registration year, wheelbase and VIN. For larger horseboxes, provide the chassis manufacturer, gross weight and axle configuration.

Bodywork, ramps and access equipment

Horsebox body parts suppliers may provide aluminium extrusion, composite panels, GRP mouldings, roof sheets, doors, locks, hinges, gas struts, windows, roof vents, skirt panels, wheel-arch sections, latches and fasteners. Ramp specialists can supply ramp boards, hinges, assist springs, cables, rollers, catches, non-slip coverings and associated hardware.

Ramp work deserves a more detailed brief than “rear ramp parts”. Confirm the ramp width and length, construction, hinge layout, spring or strut arrangement, finish, door configuration and the nature of the fault. Ask whether replacement hardware is supplied with fitting instructions and whether the supplier can advise on compatible fixings. Loading ramps, catches and hinges should be inspected as part of routine horse transport checks, alongside the internal fittings that retain and protect the horse.

Horse-area fittings and interior refurbishment

Interior suppliers support stable-area repairs and upgrades with partitions, breast bars, breeching bars, stall padding, head dividers, tie rings, haynet fittings, rubber wall lining, floor mats, drainage elements, tack lockers and ventilation equipment. When comparing products, specify the number and size of horses carried, travel orientation, partition style, intended mounting surface and whether fittings need to match an existing system.

Flooring should be treated as a system rather than merely a visible top layer. A sound floor structure, sealed edges, suitable surface covering and secure matting all matter. Buyers should schedule inspection beneath mats or plates, particularly when refurbishing an older vehicle or assessing a used horsebox for repair.

How to assess a horsebox spare-parts supplier

Price matters, but downtime, incorrect parts and weak after-sales support can be more expensive than a higher unit cost. Compare suppliers on the information they require, the traceability they provide and their ability to resolve fitment questions quickly.

• Identification process: Can the supplier match from VIN, chassis plate, component number, measurements and photographs?
• Part status: Is the item original equipment, an approved replacement or a pattern part? Ask for the precise brand and reference quoted.
• Technical information: Are drawings, dimensions, fitting guidance, load data or product instructions available when needed?
• Stock and lead time: Establish whether stock is held in the UK, supplied from Europe or made to order, especially for body panels and ramps.
• Trade account capability: Workshops and builders may need volume pricing, VAT invoices, account terms, rapid despatch and returns handling.
• Repair support: For complex parts, ask whether the supplier can refer you to an authorised repairer, installer or technical contact.

OEM, aftermarket and used horsebox parts

There is no universal best route. OEM parts can simplify matching where the original manufacturer remains active and the vehicle is within a supported range. Aftermarket parts may offer broader availability or value, but the buyer must confirm exact application rather than assume interchangeability. Used parts can be commercially sensible for discontinued trim, doors or body fittings, yet demand close condition checking and are generally a poorer choice where wear, braking, coupling or retention performance is critical.

Request a written quotation that separates the part, any fitting kit, carriage, VAT, lead time and return conditions. If the item is non-returnable, made to order or electrical, establish that before approval. For international supply, also clarify Incoterms, customs documentation, duty exposure, delivery responsibility and warranty handling in the UK.

Safety and trade considerations for UK buyers

Horse transport parts must suit the vehicle and its use, not simply fit physically. UK guidance states that a loaded trailer over 750kg must have a working brake system, while towing safety checks cover coupling connections, breakaway arrangements, tyres, wheel fasteners, lights and secure loading. These points make running-gear provenance and correct fitment central purchasing issues rather than routine consumable buying.

Vehicle weight also changes the operating context. Horseboxes over 3,500kg are subject to heavy-vehicle annual testing and plating requirements. Give suppliers the maximum authorised mass and axle information where parts could affect loading, tyres, brakes or chassis configuration. Buyers sourcing parts for commercial horse transport should also ensure their wider vehicle, welfare and operating obligations are understood independently of the parts purchase.
