What This Product Does:

• Protects the tie rod ball joint / linkage by ensuring the rubber bellow (boot) stays in the correct position, sealing out dirt, water, and grit that cause wear.
• Maintains steering durability: by keeping debris out, it helps preserve the life of tie rods, joints, and bushings.
  
• Stabilizes the boot shape so it doesn’t collapse, shift, or expose the joint under steering movement.
  
• Helps prevent premature wear of components linked to steering geometry, as a good seal reduces contamination and ensures consistent lubrication.

Symptoms & Signs Of A Failing / Missing Support:

• Torn or misaligned tie rod boot / bellow - The rubber boot may sag, shift, or pull away from its proper anchor point.
  
• Grease or lubricant loss / leakage - The joint may lose its grease or lubricant because the boot is not sealing properly.
  
• Contaminant ingress / accelerated wear - Dirt, dust, water, or grit may get into the joint, causing more rapid wear, noise, or looseness.
  
• Steering feel deterioration / looseness - Over time, the tie rod joint may become sloppy due to contamination or lubricant loss, leading to vague steering feel, play, or imprecision.
  
• Visible damage or missing piece - The support itself may be cracked, broken, or missing, leaving only the boot unsupported.
  
  

Why Replacement Matters:

• A missing or damaged bellow support can cause boot misalignment, grease leakage, and premature tie rod wear. Replacing it ensures the steering linkage remains clean, tight, and correctly sealed — preserving your Porsche’s handling precision and steering feel.

Outer Turbo Tie Rod / Bump Steer Set, Monoball.
Optimize your Porsche’s steering with this precision monoball tie rod / bump steer kit, built around the iconic turbo tie rod end. Designed for classic 911, 912, 914, and 930 models, especially those that have been lowered or upgraded, it corrects tie rod geometry to eliminate bump steer, stiffen the steering feel, and maintain alignment under full suspension travel.

Fits:

• Porsche 911 1978-1989 3.3L Turbo (930)

What This Product Does:

• Corrects tie rod angle / drop: Especially on lowered vehicles, the stock tie rod geometry can cause the tie rod ends to sit at an undesirable angle, contributing to bump steer (the tendency for the wheels to turn slightly under vertical suspension movement). The adjustable kit lets you reposition the tie rod so the geometry is closer to optimal.
• Provides a stiff, precise joint: Because it’s monoball (spherical bearing), the joint is more rigid and precise compared to a bush-type joint, with less compliance, thus improving steering feedback and consistency under load.
  
• Allows precise adjustment: Many bump steer kits allow vertical movement in fine increments (e.g. 1 mm steps) to dial the ideal steering geometry.
  
• Maintains alignment under suspension travel: As the suspension compresses or rebounds, the improved geometry helps avoid unintended steering changes (i.e. bump steer), which improves stability and handling.
  
  

Symptoms & Signs Of A Weak Tie Rod / Bump Steer:

• When driving over undulations or bumps, the wheels may steer themselves slightly (you feel the car “pull” or twitch).
• The steering may feel loose, vague, or lack consistency as the suspension travels.
• Especially at the tie rod ends, you may hear clunks, or feel play in steering when the joint is worn.

Why Replacement / Upgrading Matters:

• Correct geometry after modifications: If your car is lowered or has suspension changes, the stock tie rod alignment may cause bump steer. Upgrading to a monoball adjustable kit restores proper geometry.
  
• Improved steering precision: Rigid joints (monoball) reduce compliance and provide sharper, more direct feedback.
  
• Consistency under dynamic load: Helps maintain alignment as the suspension moves, making handling more predictable and safer at speed.
  
• Better durability: Quality monoball joints and upgraded materials withstand fatigue, wear, and stress better than aged or rubber-jointed stock parts.
  
• Essential for track / performance use: In motorsport settings, the steering must remain constant under all conditions — this kit helps ensure that.

Precision Steering Under Pressure

Our top-performing bump steer solution is super strong and provides the sharpest, most predictable steering response. It eliminates steering knuckle twist induced toe steer and can be used on raised spindles of any height.

Double steering knuckle – Holds tie rod end between two steering knuckles to eliminate knuckle flex regardless of bump steer spacer length.

Long bump steer spacers (required with raised spindles) place bending loads that twist stock steering knuckles. Twist causes undesired toe steer.

Second steering knuckle is welded to the strut body

Bump steer adjustable – allows massive bump steer adjustment range in .125 inch increments. Double shear mounting provides solid support for even the longest bump steer spacing.

Rod End – Weather sealed precision rods ends included work with regular turbo tie rods. Included boots to seal out dirt and and water for extended life.

Our purpose-made rod ends are extra long to ensure proper threaded engagement with standard turbo tie rods

Spindle height – Kits available for 19mm, 30mm, 40mm spindle height.
Kits are easily modified for use with essentially any spindle height.
