The cotter pin nut fastens the lower ball joint to the front suspension arm and secures it with a locking cotter pin through the castle slots. This prevents the nut from rotating loose, maintaining safe steering and suspension geometry during operation.
Over time, nuts can wear, corrode, or lose torque retention due to repeated assembly, age, or exposure to moisture and road debris. A weakened or reused nut may compromise the ball joint’s security, leading to excessive play or unsafe suspension movement.
When to Replace:
• During front suspension rebuilds or ball joint replacement.
• If the original nut is rusted, damaged, or has distorted threads.
• Whenever the cotter pin is replaced, ensuring proper torque and locking function.
Replacing a new cotter pin nut restores factory-level safety, alignment integrity, and reliability in your classic Porsche’s suspension system.

De-Cambered Ball Joint For A-Arm - Old Type (FI16). Porsche 911 1968-72
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
- Porsche 914 (1970-1976)
Upgrade your front suspension precision with this de-cambered ball joint, designed for early Porsche 911 and 914 models (1968-72) using the FI16 suspension system. This ball joint features an offset mounting position, delivering approx 3 mm additional negative camber per side, improving front end grip and cornering response.
Sold Each.
x2 Required Per Car.
Fits:
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
- Porsche 914 (1970-1976)
Diagram Ref No 13, 15, 16, 17
What This Product Does:
- By offsetting the ball joint mounting location, the bottom of the strut / control arm is moved slightly outward, thereby increasing the negative camber angle of the front wheels (camber meaning the top of the tire tilts inward). This helps maintain better contact patch under cornering or when the car is loaded laterally.
- Improves front end grip and handling when cornering heavily by limiting camber loss under load.
- Because it uses upgraded hardware, it ensures the A-arm to spindle connection remains precise, reducing deflection or unwanted movement compared to worn standard joints.
Symptoms & When You Might Need It:
- If you’ve lowered the front of the car, added stiffer springs or anti-roll bars, you may find the standard camber spec is insufficient — tires may roll onto the outer edge when cornering. This de-cambered joint helps adjust for that.
- Worn or loose ball joints can cause front end play, knocking noises when the steering is turned or when hitting bumps, and uneven tire wear (especially on the inner or outer shoulder). The upgrade version helps eliminate play and adjust geometry.
- Loss of front negative camber under lateral load: you might notice less cornering grip, front tires scrub or overheat on the outer edge, or the car understeers more than normal.
- Visible wear: when inspecting, you might find the original ball joint housing is worn, the stud loosened, rubber boots torn, or excessive play when lifting the wheel and wiggling the control arm.
Why This Upgrade Matters:
- For enthusiasts, track-day users or cars modified with lowered suspension and stiffer springs, the factory ball joint may no longer allow optimal camber and geometry settings. This de-cambered version gives a relatively easy bolt-in method to move the geometry in the right direction without major suspension redesign.
- It offers both improved handling (by more negative camber) and also improved front end stability and precision (by replacing worn or standard joints with a stronger, correctly designed part).
- Considering the age of 911/914 front suspension components, renewing joints such as this one is a worthwhile investment in safety, longevity and driving feel.

Enhance cornering precision and grip with the De-Cambered Ball Joint Kit, engineered for Porsche 911 and Porsche 914 models.
This “new type” FI16 ball joint includes a built-in negative camber offset of approximately 3 mm, allowing the front suspension to maintain improved tire contact during aggressive cornering.
The result is sharper turn-in, increased lateral grip, and more consistent geometry under load — all without the need for additional camber plates or major suspension modification.
Sold As A Kit.
x2 Kits Required Per Car.
Fits:
Diagram Ref No 17, 19, 20, 21
What This Product Does:
Typical Symptoms / Use-Case Indicators:
- Camber losses under hard cornering (e.g. inside shoulder lifting)
- You run aggressive alignment on track setups and want to preserve negative camber under load
- You want a simple way to bias the geometry slightly without major suspension changes
Why Choose A De-Cambered Joint:
- Improved Tire Contact Patch – Keeps the tire flatter to the road mid-corner.
- Better Cornering Balance – Reduces understeer by optimizing front grip.
- Maintains OEM Geometry – No structural modification needed.
- Durable, Race-Proven Design – Forged construction handles high loads.
- Enhanced Precision – Ideal for track-day cars, restorations, and spirited street driving.

Porsche Ball Joints | Design911 Suspension & Steering Components for Precision Handling
Ball joints are crucial pivot points in your Porsche’s suspension system, connecting the control arms to the steering knuckles and allowing smooth, controlled movement of the suspension while steering and driving over uneven surfaces. These components ensure stability, steering precision, and consistent wheel alignment — key for the responsive handling and dynamic balance that define Porsche performance.
At Design911, we supply a comprehensive selection of ball joints and suspension fittings, engineered for strength, accuracy, and long service life. Each component is built from high-grade materials to handle high loads, resist corrosion, and provide consistent performance under pressure. Perfect for routine servicing, suspension restoration, or performance upgrades, our ball joints restore steering precision and ensure your Porsche maintains its legendary road feel.
What Do Ball Joints Do?
Ball joints act as flexible connection points between your Porsche’s control arms and steering knuckles, allowing vertical and rotational movement while maintaining secure wheel alignment.
Core Functions:
• Allow smooth suspension movement and steering rotation.
• Maintain precise wheel alignment for predictable handling.
• Support vehicle weight while absorbing road impact.
• Enable suspension articulation for cornering and braking stability.
• Reduce vibration and improve ride comfort.
Ball joints are essential to maintaining both steering accuracy and suspension balance — ensuring your Porsche feels composed and connected at every speed.
Why Do Ball Joints Fail or Degrade?
Ball joints experience continuous motion, load, and exposure to harsh road conditions, leading to gradual wear or failure over time.
Common Causes of Failure Include:
• Wear of internal bearing surfaces from friction and movement.
• Corrosion or contamination inside the joint housing.
• Cracked or torn dust boots allowing dirt and moisture ingress.
• Excessive load from aggressive driving or poor road surfaces.
• Age-related material fatigue or lubrication loss.
When ball joints fail, symptoms can include clunking noises, uneven tyre wear, vague steering response, and excessive suspension play — all signs that replacement is necessary for safety and performance.
Why Replace or Upgrade Your Porsche Ball Joints?
Replacing worn or damaged ball joints restores handling precision, alignment stability, and steering feedback. Upgraded materials and performance-grade designs also enhance durability and road feel.
Key Benefits:
• Restores precise steering and handling performance.
• Eliminates suspension noise and vibration.
• Improves tyre wear and road stability.
• Available for Porsche 911, 944, 968, Boxster, Cayman, Panamera, and Cayenne
models.
• Made from corrosion-resistant, high-strength materials.
• Ideal for servicing, restoration, or performance tuning.
Design911’s Porsche ball joints deliver exceptional reliability and performance, ensuring your suspension system performs at its peak — whether on the road or the track.
Highlights
• Premium Porsche ball joints and suspension components.
• Precision-engineered for strength and alignment accuracy.
• Designed to reduce vibration and enhance control.
• Corrosion-resistant construction for long service life.
• Fits both classic and modern Porsche models.
• Perfect for suspension servicing, upgrades, or restoration.
