Manufactured to OE specifications for fit, strength and durability, the lock plate is designed to prevent movement or loosening of the ball joint retaining hardware under the constant loads and vibrations experienced during vehicle operation. It is an essential component when replacing suspension parts, carrying out front-end repairs or restoring factory-correct assembly.
What This Product Does:
- Secures and locks the front wishbone ball joint retaining hardware.
- Prevents loosening caused by vibration and suspension movement.
- Maintains correct ball joint positioning within the suspension assembly.
- Supports proper suspension geometry and alignment.
- Helps ensure safe operation of the steering and suspension systems.
- Contributes to the long-term reliability of front suspension components.
Symptoms Of Wear Or Failure:
- Loose ball joint retaining hardware.
- Unwanted movement within the suspension assembly.
- Knocking or clunking noises from the front suspension.
- Difficulty maintaining correct wheel alignment.
- Increased wear on ball joints and suspension components.
- Visible corrosion, bending or damage to the lock plate.
- Reduced security of suspension fasteners.
- Potential suspension safety concerns if retaining hardware loosens.
Why Replacement Matters:
- Lock plates are designed to provide a secondary level of security for critical suspension fasteners. Over time, corrosion, fatigue, improper installation or damage during servicing can reduce their effectiveness. Reusing worn or distorted locking components may compromise their ability to properly secure suspension hardware.
- A damaged or missing lock plate can allow retaining fasteners to gradually loosen, increasing the risk of suspension component movement and accelerated wear. In severe cases, insufficient retention of critical steering and suspension parts can affect vehicle handling and safety.
- Replacing worn or damaged lock plates helps maintain correct suspension assembly integrity, ensures secure fastening of ball joint components and supports safe, predictable vehicle handling. An OE Match replacement restores factory-style fitment and provides dependable long-term security for the front suspension system.

Wishbone ball joint front - cotter pin
Ball joint lock pin is an suspension fastener designed to secure the front lower ball joint to the strut or wishbone assembly on classic Porsche models. It installs into the ball joint mount to secure the connection between suspension links and steering knuckles. It’s suitable for maintenance, rebuilds, or restoration of front suspension components and fits directly without modification.
Sold each, Fits left and right.
Fits:
Porsche 911 1969 - 1989
Porsche 914 1972 - 1976
Diagram ref no 20
The lock pin provides a secure fastening point that holds the front lower ball joint in place, ensuring the suspension components remain correctly aligned under load and motion. It helps transmit steering forces while keeping the joint assembly stable during driving.
Installed through the ball joint and suspension link interface, this pin maintains clamping and positional integrity, aiding the suspension’s ability to articulate smoothly while resisting unwanted movement. It works in conjunction with the control arm and steering knuckle to support safe, responsive handling.
Front suspension hardware like the ball joint lock pin can wear, corrode, or lose clamping strength over time, which may lead to play in the suspension, uneven tyre wear, and compromised steering feel. Replacing worn or damaged pins with OE Match parts helps maintain precise suspension geometry and consistent handling characteristics.
When to replace:
• Ball joint pin is corroded, bent, or worn
• Loose or sloppy front suspension feel
• During ball joint, control arm, or strut service
• Restoration of classic suspension systems
• After removal or disassembly of front suspension

Designed for direct installation into compatible A-arms, it provides a robust and reliable solution for vehicles used on the road, track or in competition.
What This Product Does:
- Connects the front A-arm to the steering knuckle.
- Provides additional negative camber for improved suspension geometry.
- Improves front-end grip during cornering.
- Enhances steering precision and responsiveness.
- Maintains smooth suspension articulation.
- Supports improved handling in performance applications.
- Provides factory-style fitment for compatible upgraded suspension systems.
- Forms an essential part of the front suspension assembly.
Symptoms Of Wear Or Failure:
- Knocking or clunking noises from the front suspension.
- Excessive steering play.
- Uneven or accelerated tyre wear.
- Reduced steering precision.
- Vehicle wandering or instability.
- Vibration through the steering wheel.
- Excessive movement in the suspension joint.
- Split or damaged protective dust boot.
- Grease leakage from the ball joint.
- MOT or vehicle inspection failure due to excessive suspension play.
Why Replacement Matters:
- The ball joint is a critical suspension component that allows the steering knuckle and control arm to move freely while supporting the vehicle's weight. It is continually subjected to heavy braking, cornering forces, road impacts and suspension movement. Over time, internal wear, contamination or deterioration of the protective dust boot can lead to excessive play and reduced suspension accuracy.
- A worn ball joint can negatively affect steering response, wheel alignment and tyre wear while increasing the risk of suspension instability. In performance applications, worn components can significantly reduce handling precision and driver confidence.
- Replacing a worn or damaged ball joint with the OE Match De-Cambered Ball Joint restores accurate suspension geometry and improves front-end handling for compatible performance suspension setups. Manufactured from premium forged materials with precision-engineered internal components, it provides factory-style fitment, exceptional durability and the increased camber required for enhanced road holding and motorsport performance.

Groove nut for front wishbone ball joint
This groove nut is used to secure the front lower wishbone (A-arm) ball joint on classic Porsche suspension systems. Manufactured to the exact dimensions and thread specifications of the original Porsche part, it provides reliable clamping strength and precise seating of the ball joint within the control arm.
Sold each, fits left and right
Fits:
Porsche 911 1969 - 1989
Porsche 914 1972 - 1976
Diagram ref no 17
This groove nut locks the ball joint securely into the front wishbone, maintaining correct alignment and preventing movement under cornering loads and braking forces. Its machined groove design allows for proper engagement with a locking ring or pin, ensuring long-term stability and safety.
With age, the original groove nut may corrode, lose thread integrity, or deform during removal. Using a worn or non-spec nut can lead to incorrect torque, potential loosening, or suspension play.
