De-Cambered Ball Joints
Easy Bolt-on To More Front Negative Camber

Need more camber? Elephant Racing's proprietary-design De-Cambered Ball Joints provide up to 3/4 degree additional negative camber per side. Track is widened up to 1/2 inch.

The ball joint stud is non-concentric with the housing, effectively lengthening the control arm and pushing the bottom of the strut (and tire) out resulting in added negative camber.

Construction includes a true spherical bearing monoball for low-friction, freedom of movement and zero deflection.

Fully weather-sealed, De-Cambered Ball Joints are a true bolt-in using factory ball joint hardware.

Combine these with Rennline adjustable camber plates and monoball mounts for maximum adjustability on the track and the street. These are a perfect compliment for any street or track suspension, and are a must have for those looking to precisely dial in the ultimate alignment setup.

What This Product Does:
  • As the suspension moves up and down over bumps, the ball joint allows controlled pivoting and articulation of that joint while maintaining alignment and keeping the wheel geometry stable.
  • It must hold under load, lateral forces, and steering inputs, ensuring the wheel moves in the intended path without play or deflection.

Symptoms Of Wear Or Failure:
  • Steering play / looseness — the steering may feel vague or “sloppy.”
  • Knocking or clunk noises — a distinct knock over bumps or during suspension travel.
  • Uneven or rapid tire wear — particularly on the front tires, due to misalignment or movement under load.
  • Vibration or shimmy — especially during cornering or when driving over uneven surfaces.
  • Borderline geometry shifts — alignment may change subtly when load is applied or when cornering.
  • Reduced road feel / control — the front end may feel less precise or less responsive.

Why Replacement Matters:
  • Restores Steering Precision & Control - Worn joints introduce slack and movement. Replacing them ensures crisp, direct response from your steering.
  • Maintains Alignment Under Load - A healthy ball joint holds the wheel geometry consistent even when cornering or under load.
  • Prevents Further Suspension Damage - Allowing play in a ball joint transfers forces to other components — control arms, bushings, knuckles, etc. Replacing it protects the rest of the suspension.
  • Eliminates Noise & Harshness - New joints operate cleanly with no unwanted knocking or vibration.
  • Safety & Reliability - Because the ball joint is a critical steering link, a failed joint can degrade or compromise safe vehicle control. Having robust, correctly functioning joints is essential.

Replace your tired ball joints to restore the original steering, worn ball joints degrade steering precision. Ball joints connect the front strut to the control arms and a failure causes loss of control. To avoid potential safety issues, street cars should replace at 100k miles, track cars more often.

About Ball Joints

Porsche Ball Joints

At Design911, we supply performance and replacement ball joints for Porsche models, helping you restore precise steering feel and keep your suspension working as intended.

Our product range in this category

Use the filters on this page to narrow down ball joints and related hardware by Porsche model, year and position on the car.

Why do Porsche Ball Joints matter?

Ball joints are pivot points in your Porsche suspension, sitting between the control arms and the steering knuckles. They allow the wheels to move up and down with the suspension while also steering smoothly from lock to lock. Over time, the joints can wear internally or their protective boots can split, allowing dirt and moisture in. This leads to play, noise and less precise steering, and in severe cases can compromise safe suspension movement.

  • Maintain accurate steering and predictable handling on your Porsche
  • Help keep alignment and suspension geometry within specification
  • Address knocking, looseness and other symptoms of wear before they worsen
  • Support long-term safety, tyre life and overall confidence in the car

When should you review or replace your Porsche ball joints?

Checking ball joints regularly helps you spot wear, damage or age-related deterioration before it affects steering precision or leads to more extensive suspension repairs.

  • Knocking, clunks or vibration from the suspension area over bumps
  • Steering that feels vague, wanders or needs constant correction
  • Uneven or accelerated tyre wear that points to geometry issues
  • Play or roughness detected in the joint during inspection, or split dust boots letting in contamination

If any of these apply, it is a good time to review your ball joints and replace anything that is past its best so your Porsche stays dependable and reassuring to drive.
