Complete steering tie rod assembly with part number 128/13949 from the GX-AFTER offer. It is a key steering system component, dedicated to heavy JCB backhoe loaders equipped with two steering axles (4WS). The rod is responsible for transferring force from the hydraulic cylinder directly to the wheel knuckles, ensuring steering synchronization. Robust construction with a 40 mm diameter tube guarantees resistance to bending in difficult terrain.
GX-AFTER rods are made of high-grade forged steel, which provides the rigidity necessary to maintain correct wheel geometry, even when operating in "crab" mode with a full loader bucket load.
| Brand | Models (with two steering axles) |

| JCB | 3CX SUPER, 4CX |
The rod fits only machines with equal wheels and two steering axles. Check length (590 mm) before purchase.
After replacing the rod, wheel alignment check is necessary. It is also worth checking the condition of the steering cylinder (for leaks) and knuckle pins, as play in these areas accelerates rod wear.
A bent steering rod drastically changes wheel geometry, leading to instant tire destruction and unpredictable machine behavior on the road. Straightening rods is prohibited – the disturbed steel structure may snap at the least expected moment.
Rod 128/13949 connects the wheels of a given axle, ensuring their parallel operation.

In 4CX machines, the front axle acts as a pushing axle during loader bucket work. The forces acting on the wheels try to "spread" them. The thick 40 mm tube prevents the rod from buckling under these powerful forces.
It is a complete subassembly, consisting of a connecting tube and two tie rod ends (usually one with a left thread, the other with a right thread), ready for installation.
In "crab" mode (diagonal driving), both steering axles set the wheels in the same direction . For this mode to work correctly and not destroy tires, the length of the steering rods on both axles must be perfectly matched and adjusted.
