Traditional UK horsebox builders have a deep-rooted heritage of building heavy, bespoke wooden-finish interiors. Stephex challenges this legacy by introducing a modern, European automotive-grade finish using lightweight carbon-fiber looks. This modern design drastically reduces the unladen weight of the vehicle, providing superior safety engineering, better fuel efficiency, and higher legal payload capacities compared to legacy horse lorries. This ensures your horses travel in the ultimate climate-controlled comfort.

Explore AKXLuxury Horseboxes for Sale
Explore our latest stock of new STX, new AKX and pre-owned Luxury Horseboxes for Sale, engineered to provide the absolute highest standards of safety, comfort, and reliability for both horse and rider. Whether you are looking for an agile 3.5t lorry for quick trips to local shows, a versatile 7.5t horsebox for stay-away weekend competitions, or a full full-HGV vehicle for an international racing yard, our curated collection is ready for the road.
Every Stephex vehicle we offer represents a total departure from the traditional, heavy wood-finish horseboxes often found in the UK. Instead, we deliver a sleek, modern European aesthetic featuring lightweight carbon-fiber styles and automotive-grade finishes. This intelligent, high-performance engineering reduces unnecessary weight, optimises fuel efficiency, and provides superior climate control to ensure your horses travel in absolute comfort.
More importantly, our design prioritises advanced equine safety and performance mobility. From robust stallion configurations to impact-resistant side walls and custom ventilation systems, your investment and your horses are protected at every stage of the journey. Backed by our expert UK knowledge, comprehensive handovers, and dedicated mobile repair support, finding your next premium transport solution has never been more seamless.
Key Considerations When Looking for a 3.5t Lorry for Sale
When searching for the ideal 3.5 t horsebox for sale, payload efficiency and safety engineering should always be your primary considerations. Many traditional horse lorries in the UK feature heavy, wooden-finish interiors that significantly reduce the legal weight you can carry. A major advantage of the Stephex design is our lightweight, carbon-fiber style, which maximises your available payload without compromising on structural safety. This allows you to transport your horses, tack, and equipment while staying completely within legal UK road limits.
Whether you are looking to buy horse truck configurations for a professional yard or a compact 3.5 ton lorry for weekend events, always inspect the ventilation systems, bulkhead strength, and ramp stability. Investing in a premium 3.5ton horsebox for sale ensures that your horses travel in a stress-free environment and arrive at the venue completely relaxed. Furthermore, because Stephex vehicles are built on world-class chassis frameworks like Mercedes and Renault, they maintain an exceptional resale value, making your purchase a secure, long-term financial investment.

Frequently Asked Questions About Stephex Horseboxes UK
What makes Stephex Horseboxes different from other brands?
Can I purchase pre-owned or used horseboxes directly from Stephex Trucks UK?
Yes, we frequently feature a premier selection of premium pre-owned and used horseboxes for sale UK wide. Stephex vehicles are world-renowned for maintaining exceptional resale value due to their durable chassis engineering and premium build quality. Every used horse truck undergoes a rigorous safety, mechanical, and structural inspection by our specialist team before handover to ensure complete peace of mind.
Do you provide servicing and repairs?
We offer complete ownership confidence through our dedicated UK aftersales support team. This includes comprehensive factory warranties, rapid access to genuine replacement parts, and a nationwide horsebox mobile repairs network. If an issue arises while you are at a show jumping event or at home, our mobile technicians can come directly to your yard to minimise your downtime and keep your truck moving flawlessly.
Do you offer financing or leasing options?
Yes, we offer highly flexible, competitive financing and leasing solutions tailored for both personal and commercial business needs. We understand that acquiring a luxury asset requires careful capital management, which is why we work alongside specialist equestrian lenders to structure packages that suit your specific financial requirements.
Our bespoke finance options include tax-efficient leasing, structured hire purchase agreements, VAT deferrals mapped to your cash flow, small initial deposits, and lower monthly payments with larger balloon options. Whether you are an elite amateur buyer investing in an AKX model or a professional racing yard acquiring an STX flagship vehicle, our team is here to guide you seamlessly through the funding process. Please see our dedicated finance page for further information or to start your application.
What is the difference between an STX and an AKX horsebox?
The STX is our flagship, fully customisable range built on Mercedes, Scania, or Volvo frames, offering bespoke configurations for up to nine horses. The AKX is our functional luxury range, built on a standardised Mercedes chassis, providing a “ready-to-go” luxury configuration with faster delivery times at a more accessible price point.
What driver’s licence do I need for a 3.5t lorry vs a 7.5t horsebox in the UK?
To drive a 3.5t lorry or horsebox in the UK, you only need a standard category B car licence, making it incredibly accessible for casual hobbyists and professional riders alike. However, to operate a larger 7.5t horsebox, you will need a category C1 licence. If you passed your UK driving test before 1st January 1997, you likely have this qualification automatically. If you passed after this date, you will need to take an additional medical and practical driving test to upgrade your licence for larger horse lorries.
Can I customise my Stephex horsebox?
Yes, we offer extensive options to customise your Stephex horsebox to meet your exact personal or professional requirements. Our flagship STX range represents the pinnacle of bespoke design, allowing you to tailor everything from the living accommodation layouts and automotive-grade finishes to the configuration of the equine area. Built on premium Mercedes, Scania, or Volvo frames, these heavy-duty vehicles can be fully customisable to safely transport up to nine horses in world-class comfort.
If you are looking for a compact 3.5t lorry or a versatile 7.5t build, we provide a wide range of premium configurations, luxury leather options, and layout extras. However, if you prefer a faster delivery time without navigating a lengthy customisation process, our AKX range offers a standardised, “ready-to-go” luxury build on a dependable Mercedes chassis at a more accessible price point. From luxury motorhomes with integrated garages to high-volume horse trucks, our team helps you secure the perfect transport configuration.
How long does it take to build a custom horsebox?
Production times for a custom build vary depending on your specific requirements and chosen chassis configurations. As a general guide, we advise approximately 4–5 months for a 2-horse truck (such as our high-volume 3.5t lorry models) and roughly 5–7 months for our larger HGV horse vehicles. This timeline ensures that every safety engineering detail, climate-control system, and bespoke internal finish is executed to absolute perfection.
However, if you require a luxury vehicle immediately to meet an upcoming competition or racing schedule, we also maintain a premier selection of “ready-to-go” builds. Our AKX range offers standardised, luxury configurations at a more accessible price point with significantly faster availability. Additionally, we frequently carry physical, factory-direct stock models and certified pre-owned vehicles that are available for immediate delivery.
