The inner tie rod transfers movement from the steering rack and pinion system to the outer tie rod and wheel hub, enabling accurate steering control.

As part of the steering linkage, it ensures precise wheel direction, stability, and alignment, while allowing articulation as the suspension moves.

Functions & Technical Role
•  Steering transmission: Transfers movement from steering rack to wheels
•  Alignment control: Maintains correct tracking and geometry
•  Articulation: Works with ball joints for smooth suspension movement
•  Stability support: Ensures responsive and predictable steering
•  OEM precision: Engineered to Porsche tolerances for durability and performance

Tie rods are critical components linking the steering system to the wheel spindle, and wear can directly affect handling and tyre wear.

Fitment / Position on car:
•  Fitting position: Front axle
•  Location: Inner steering linkage (between steering rack and outer tie rod) 

Inner tie rods are subject to constant load, vibration, and steering movement. Over time, wear can lead to:
•  Loose or vague steering feel
•  Uneven tyre wear
•  Knocking or play in steering
•  Poor alignment and handling

Replacing with a genuine Porsche OE rack end restores steering precision, improves safety, and ensures long-term reliability.
