Replacement Bush Set For Lower Rocker Arm. Porsche 928

Replacement Bush Set For Lower Rocker Arm.
Bring back the solid, composed feel of your Porsche 928’s rear suspension with this Replacement Bush Set for Lower Rocker Arm.
Located within the rear rocker arm assembly, these bushings control the articulation of the lower suspension arms, maintaining proper geometry and stability during acceleration, braking, and cornering.
Sold As A Set.

What This Product Does:

• Holds the rocker arm in place, connecting it to the chassis or subframe while allowing pivoting motion.
• Allows the rocker mechanism to articulate smoothly, transferring load between trailing arms or controlling geometry changes.
• Helps maintain consistent suspension geometry under load — i.e. when the car is accelerating, braking, or cornering.
  
• Reduces unwanted movement or slack in the linkage, preserving handling precision and stability.

Symptoms Of Worn Or Damaged Bush:

• Clunking or knocking noises from the rear over bumps or during suspension movement
  
• Rear-end vagueness or instability — the car may feel less planted or “loose”
  
• Uneven or strange tire wear on the rear tires, due to misalignment or shifting geometry
  
• Suspicion that the rear changes behavior under load (e.g. under acceleration / braking)
• Reduced handling precision, especially in transitions or fast directional changes
  
  

Why Replacement Matters:

• Restores handling precision — replaces worn, sloppy bushings with tight, controlled support
  
• Eliminates noise & play — stops knocking or slack in the rocker arm linkage
  
• Protects suspension geometry — ensures the rocker arm acts as intended, maintaining correct alignment under load
  
• Prevents further wear — worn bushings transfer stress to surrounding arms, brackets, or linkage elements
  
• Improves confidence & stability — rear responses become more predictable, especially at higher speeds or in aggressive driving
