Steering tie rod end with part number 331/37238 from the GX-AFTER offer. It is a massive steering component with a length of 220 mm and M28x1.5 thread. Designed specifically for JCB machines with a 4-wheel steering system (4WS), such as 3CX SUPER and 4CX models. This end is responsible for precise transfer of steering force in heavy off-road conditions, ensuring machine stability.
Thanks to the M28x1.5 thread and reinforced construction, GX-AFTER tie rod ends are adapted to work in "crab steer" mode (sideways driving), where the forces acting on the steering system are significantly higher than in standard machines.

Part intended exclusively for models with two steering axles (4WS). Check thread M28x1.5.
When replacing an M28 size end, check the condition of the steering rod (for thread damage) and the tightness of the steering cylinder. Replacing tie rod ends in pairs ensures easier alignment setting.
Play on tie rod ends in 4CX machines is dangerous, especially at higher speeds on the road (above 30 km/h). It can cause machine "wandering". Tie rod end breakage threatens a complete loss of vehicle control.

JCB 3CX Super and 4CX machines have equal wheels and driven, steerable axles on both ends. The forces generated during steering in muddy terrain are immense, hence the necessity for such robust threaded connections.
This is the total length of the element from the end of the thread to the center of the ball joint. This allows the new end to be preset in the same position as the old one, facilitating alignment adjustment.
JCB 4CX machines feature a steering mode called **"crab steer"** (diagonal driving), where all wheels turn in the same direction . This allows the machine to move "diagonally," which is extremely useful when working along walls or trenches. Functional tie rod ends are crucial for the precision of this maneuver.
