Ifor Williams HBX511 Horse Trailer

The Ifor Williams HBX511 represents the absolute pinnacle of luxury equestrian transport. Superbly engineered with an all-aluminium body and an aerodynamic, streamlined roof, the flagship HBX range combines striking aesthetics with incredible structural strength. This particular double horsebox is a premium, high-specification factory configuration, equipped with high-performance axle dampers for an ultra-smooth ride, protective internal padding boards, diamond-cut alloy wheels, and an integrated high rear brake light for enhanced road safety.

Designed with both the handler and horse in mind, the HBX511 comfortably accommodates two large horses up to 17.2hh. The lightweight yet exceptionally strong aluminium body panels merge seamlessly with a unique floating roof design and a magnificent, large front styling window, giving the trailer its iconic, highly recognisable silhouette. Inside, the comfort and safety of your horses are managed by a full centre partition system, two sets of adjustable breast and breeching bars, a pair of side windows, and a large front inspection window. The trailer handles impeccably under full load by pairing the legendary Ifor Williams heavy-duty beam axles and leaf-sprung suspension with commercial-grade 165R13C tyres on upgraded diamond-cut alloy wheels. 

Innovative Dual-Function Combination Rear Ramp

The rear loading ramp offers a brilliant, dual-function design:

• Traditional Loading Ramp: Lowers downwards to provide a secure, stable, and low-angled approach for seamless equine loading and unloading.

• Side-Hinged Door: Swings open horizontally like a standard door. This allows for incredibly fast and convenient cleaning out of the horsebox bedding and permits easy forklift access directly to the rear deck for loading hay bales or feed pallets.
