311-511-245 VW Rear Spring Plate Bushing - "Knobby" Style

"Knobby" Spring Plate Bushing – 311-511-245

The 311-511-245 is a high-density rubber component critical for any rear suspension overhaul. Because these bushings support a significant portion of the vehicle's rear weight, they are often found compressed or cracked after decades of service. Using a factory-style "knobby" rubber bushing rather than a hard urethane version maintains the original "German Feel" of the suspension, offering better vibration dampening for street-driven cars.

This bushing is compatible with a wide range of Type 1, Type 3, and early Type 2 vehicles. It is specifically sized to fit over the spring plate collar and inside the torsion housing cap.

• Vibration Isolation: Effectively isolates the chassis from road noise and harshness transmitted through the rear torsion bars.

• Exact OEM Dimensions: Guaranteed fit for the 1-7/8" (approx.) inner diameter housing common on most air-cooled rear ends.

Technical Specifications

• Part Number: 311-511-245

• Style: Knobby (Round with protrusions)

• Position: Left-Outer / Right-Inner

• Material: High-Density Rubber

Installation & Maintenance Tips

• Use Proper Lubrication: Only use a rubber-safe lubricant (like glycerin or specialized rubber grease) during installation. Never use petroleum-based grease, as it will cause the rubber to swell and degrade rapidly.

• The "Soap" Trick: If the bushing is difficult to seat into the housing, a small amount of liquid dish soap can act as a temporary lubricant that dries up and lets the "knobs" lock into place.

• Check the Mates: Since these are sold individually, always check the opposite side (Left-Inner / Right-Outer) for wear. Suspension components should always be refreshed in complete sets to maintain balanced handling.
