About Kartt UK

Kartt is a British premium manufacturer that has redefined the market for trailer jockey wheels through radical innovation. Under the brand name “Kartt Orange”, the company produces components specifically developed for maximum load capacity and effortless operation. Kartt products are the first choice for users who refuse to compromise on stability – whether on a heavy commercial trailer, a horsebox or a caravan with a motor mover.

Technical innovations “Made in UK”

Kartt stands out through details that are often missing from standard original equipment. The focus is on preventing wear caused by friction and vibration.

  • Turn-Lok™ technology: A patented device that prevents the handle from unwinding by itself due to vibration while driving and lowering the jockey wheel.
  • Maintenance-free bearings: High-quality nylon and roller bearings make height adjustment extremely smooth, even under high nose weight (up to 3500kg on heavy-duty models).
  • Reinforced tube walls: The inner and outer tubes are thicker than on standard models, which greatly increases torsional rigidity during manoeuvring.
  • Kartt Orange wheel: The distinctive orange steel rims with wide rubber tyres offer optimum directional stability on soft ground and are puncture-proof.

Applications and upgrades

The Kartt Ultimate jockey wheel is particularly popular as an upgrade for existing vehicles. It is compatible with the common clamp brackets (48mm / 60mm) and, thanks to its robust construction (wheel forks up to 8.5mm thick), offers a considerably longer service life than conventional zinc-plated jockey wheels.
