Steering tie rod end with part number 8U3381 from the renowned TORS brand offer. It is a component mounted on the right side of the steering system in Caterpillar (CAT) wheeled excavators. This joint is responsible for transferring force from the steering cylinder to the wheel knuckle, enabling smooth and precise maneuvering of the heavy machine.
The TORS brand is a guarantee of reliability in difficult conditions. The reinforced ball stud socket and high-quality rubber boot ensure protection against mud, water, and sand, which significantly extends the component's life compared to standard replacements.

Joint dedicated to the right side of the steered axle. Before purchasing, ensure whether you need the right or left side (they differ in thread).
When replacing the right joint, it is worth checking the condition of the left joint and the axial rod. New castle nut and cotter pin (if required by design) and grease may be needed for installation.
Play in the steering joint causes unstable excavator handling ("wandering") at higher transport speeds. Joint failure while driving threatens a complete loss of steering control and an accident.
Joint 8U3381 is the link between the cylinder and the knuckle.

Steering systems typically feature left and right threads (or other asymmetry) to allow toe adjustment by rotating the center rod. This element has a specification matching the right side of the machine.
No. Tracked excavators do not have a steering system with knuckles and rods (they steer via track speed difference). This joint fits wheeled excavators (M3xx series).
The M series wheeled excavators (e.g., M318) are known for their mobility. They can travel on public roads at speeds up to 35 km/h. At such speeds, a functional steering system without play is absolutely critical for safety.
