Product Information
Heavy Duty Front Control / A-Arm Bushings Set.

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.

Symptoms / Signs Of Wear Or Soft Bushings:
  • 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)

Why Upgrade to Heavy Duty Bushings:
  • 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.
