Enhance your Porsche’s steering precision and suspension performance with the Heavy Duty Front Control / A-Arm Bushings Set.
Designed as a direct-fit replacement for worn factory rubber bushings, this HD set features a stiffer, high-durometer compound (~25% firmer than OEM). It minimizes unwanted A-arm flex, keeping your suspension geometry tight and predictable during aggressive cornering, braking, and acceleration.
Sold As A Set Of 4.
x1 Set Required Per Car.

What This Product Does:
- Pivot / Movement — Let the control arm move in its intended direction as the suspension rebounds or compresses.
- Control & Constrain Motion — Prevent unwanted lateral, fore/aft, or rotational movement of the control arm (i.e. limit flex).
- Isolate Vibration & Noise — Absorb and damp small road-induced vibration or harshness before it transmits to the chassis.
- Maintain Geometry — Help keep consistent alignment (toe, camber) under dynamic loads — braking, acceleration, cornering — by resisting unwanted deflection.
- Steering “slop” / looseness — the front feels less precise, vague in response
- Clunks / knocking over bumps or when braking/accelerating
- Uneven or accelerated tire wear (front tires) due to alignment shifts
- Wandering or drifting behavior under cornering or over undulations
- Excess vibration or harshness in the ride, especially at higher speeds or over rough roads
- Loss of front-end stability — particularly under load (hard cornering, braking)
- Sharper Steering Response – Eliminates compliance that dulls handling.
- Improved Suspension Geometry – Keeps camber and toe settings consistent under load.
- Enhanced Durability – Resistant to deformation, heat, and aging.
- Better Handling Feedback – Feels tighter and more connected to the road.
- Ideal for Street or Track Use – A perfect blend of comfort and control.

Manufactured to OE specifications, this replacement lower wishbone delivers the correct fit, strength and durability required for both daily driving and spirited road use. Whether you are refreshing a tired suspension, correcting handling issues or undertaking a complete restoration, replacing worn suspension arms is essential for preserving safety, comfort and performance.
What Does the Front Lower Wishbone Do?
The front lower wishbone, often referred to as a control arm, forms a vital part of the Porsche 993 front suspension system. It connects the wheel carrier assembly to the chassis while controlling wheel movement during suspension travel.
Working together with suspension bushes, ball joints,
dampers and steering components, the lower wishbone helps to:
- Maintain accurate wheel alignment.
- Control suspension movement and geometry.
- Improve steering precision and feedback.
- Enhance vehicle stability under braking and cornering.
- Reduce unwanted wheel movement.
- Deliver predictable handling and road holding.
The Porsche 993 introduced significant suspension improvements over previous generations, making properly functioning wishbones critical to maintaining the vehicle's renowned driving characteristics.
Why Do Front Lower Wishbones Fail?
Over time, front suspension components are subjected to
significant mechanical stress and environmental exposure. Common causes of
wishbone failure include:
- Corrosion caused by moisture and road contaminants.
- Impact damage from potholes, kerbs or road debris.
- Metal fatigue from years of suspension loading.
- Distortion following accidents or suspension impacts.
- Wear around bush and mounting locations.
- Excessive stress caused by worn bushes or ball joints.
As Porsche 993 models continue to mature as modern classics, original suspension components often show signs of wear that can negatively affect ride quality and handling performance.
When Should a Front Lower Wishbone Be Replaced?
The front lower wishbone should be inspected regularly as
part of routine suspension maintenance. Replacement may be necessary if you
experience:
- Clunking or knocking noises from the front suspension.
- Excessive play in suspension components.
- Uneven tyre wear. Poor steering response or vague handling.
- Vehicle pulling to one side.
- Alignment issues that cannot be corrected.
- Visible corrosion, cracking or impact damage.
- During a complete front suspension rebuild.
Replacing worn wishbones restores suspension accuracy, improves steering feel and helps return the vehicle to factory handling standards.
