Enhance your Porsche’s handling and ride precision with this Heavy-Duty Spring Plate Bushing Set.
Designed for rear torsion bar suspension systems on air-cooled Porsche 911 and 912 models, these upgraded bushings replace the factory rubber mounts that support the spring plate.
Sold As A Set Of 4.

What This Product Does:
- The spring plate is part of the torsion bar suspension system: as the rear suspension moves, the torsion bar twists, and the spring plate (with its bushings) transmits those torsional loads to the chassis.
- The bushings isolate vibration and reduce noise, and they allow some controlled movement, while preventing excessive play.
- A correctly functioning spring plate + bushing assembly helps maintain rear ride height, alignment consistency, and smooth articulation of the rear suspension under dynamic load.
- Clunking / knocking noise at the rear when driving over bumps or under load.
- Sagging or uneven ride height at the rear (one side lower)
- Excessive rear vibration or harshness under acceleration or load
- Contact / rubbing noise — the worn bushings may allow the spring plate to contact its cover or adjacent metal surfaces.
- Degraded handling / instability in the rear under cornering
- Loss of the “tight” feel in the rear suspension; more play in the rear suspension response
Why Replacement Matters:
- Restores Rear End Stability & Ride Quality: The upgraded, stiffer bushings reduce unwanted movement and maintain better control under load.
- Preserves Correct Geometry & Height: Keeps torsion bar and spring plate alignment tight, preventing sag or misalignment over time.
- Reduces Noise & Harshness: Eliminates metal-to-metal contact and vibration that results from deteriorated rubber.
- Better Durability: Heavy-duty rubber compound resists deformation, aging, heat, and oil.
- Protects Other Components: Reduces stress on torsion bars, suspension arms, and adjoining parts that might be damaged by excessive play.
- Essential for Restoration / Rebuilds: When rebuilding rear suspension or restoring a classic 911, these bushings are part of a full refresh to return the car to factory (or better) behavior.
