Increased Length 38MM Turbo Track Rod Assembly. Porsche 911 / 914 1969-89

Increased Length 38MM Turbo Track Rod Assembly.
Upgrade the front steering linkage of your classic Porsche with this high-performance, increased-length track rod assembly offering +38 mm extra length. Designed for the Porsche 911 (1969-89) and 914 (1970-76) with lowered ride height or modified front suspension geometry, this rod gives the necessary adjustment range to maintain proper steering geometry, eliminate binding and improve thread engagement. Ideal for road, performance or track use, this assembly provides extra flexibility, precision and durability for suspension-modified vehicles.

What This Product Does:

• The track rod (tie rod) connects the steering rack to the steering knuckle/steering arm, allowing the front wheels to respond to steering input. In classic 911/914 cars the standard length is optimised for standard ride height and steering geometry.
• When you lower a vehicle, change front ride height, fit stiffer springs, wider tyres or change front geometry, the original tie rod length may no longer maintain correct rod end engagement, steering rack to knuckle alignment, or sufficient thread engagement for safe mounting.
• An increased-length track rod gives extra adjustment range and corrects for the altered vertical/horizontal geometry by providing extra length, which helps maintain correct steering geometry, avoid binding, ensure full thread engagement, and reduce bump-steer or misalignment under load.
  
• Specifically the +38 mm version provides considerably more length than standard, giving more flexibility for extreme lowering or wide tyres/modified front hubs.

Symptoms & Signs You Might Need It:

• After lowering the front ride height significantly, the original tie rods are too short (leading to lack of adjustment, bound joints, or risk of insufficient thread engagement).
• Steering geometry issues such as bump-steer, uneven tyre wear, or altered steering feel (e.g., the front wheels feel unstable, wander, or kick in bumps) – these can be caused by improper tie-rod length relative to wheel/knuckle geometry.
  
• Visual inspection: the tie-rod ends are near the limit of adjustment (either fully extended or fully retracted), or the threads of the original rods are nearing their limit.
• You are running a performance setup (wider tyres, different hubs, lowered suspension) where the standard rod length restricts your alignment or fine-tuning.
• If one side of the front geometry is different (e.g., due to camber adjustment or lowered on one side) and standard rods don’t allow symmetric correction.

Why This Upgrade Matters:

• Preserves steering geometry: With modified suspension or ride height, correct rod length is essential to maintain proper steering rack to knuckle relationship, avoid undue forces, ensure proper articulation and reduce wear on joints.
  
• Improves safety and precision: Ensuring that the tie-rod ends have sufficient thread engagement and correct length helps avoid failure or undesirable steering behaviour under load.
  
• Supports performance modifications: If you’ve lowered the car, increased front negative camber, fitted wider tyres or track-prepared it, the standard rods often become a compromise — an increased-length rod restores capacity and tuning range.
  
• Reduces bump-steer/inconsistent behaviour: By allowing correct geometry under lowered height, the longer rod helps reduce unintended toe change under suspension movement, improving steadiness.
  
• Restoration/fitment: For highly modified or custom builds (wheels, track width, hub offsets) this rod gives the flexibility to adapt without resorting to custom rod making.
