111-511-245E VW Beetle & Ghia Rear Spring Plate Bushing (Outer IRS / Swing Axle)

VW Rear Spring Plate Rubber Bushing – 111-511-245E

The 111-511-245E is a versatile rear spring plate (torsion bar) bushing designed for both early and late air-cooled Volkswagen rear suspension systems. Often referred to as a "knobby" or "round" grommet, this heavy-duty rubber component is vital for isolating the rear spring plate from the torsion housing and cover plate. By absorbing road vibrations and allowing the spring plate to rotate smoothly as the suspension travels, it prevents metal-to-metal contact and eliminates the "clunking" sounds often associated with old, flattened bushings.

This specific part number covers two distinct fitment eras: it serves as both the Inner and Outer bushing for very early Swing Axle cars, and the Outer bushing for later IRS (Independent Rear Suspension) models. Because the rear suspension carries the weight of the engine and transmission, these rubber bushings are prone to being "squashed" out of round over time. Replacing them with the 111-511-245E restores factory ride height and ensures your rear alignment remains stable under load.

Detailed Vehicle Compatibility This bushing fits a wide range of models across two different suspension eras:

VW Beetle (Standard):

• 1945, 1946, 1947, 1948, 1949, 1950, 1951, 1952, 1953, 1954, 1955, 1956, 1957, 1958, 1959

• 1968 (with Autostick)

• 1968 (with Autostick)

• 1969, 1970, 1971, 1972, 1973, 1974

Product Highlights & Features

• Durable Rubber Compound: Manufactured to original shore-hardness specifications to provide the perfect balance between suspension support and vibration dampening.

• Dual-Era Fitment: Engineered to work as the inner/outer for early swing axles and the outer for later IRS setups, making it a staple for any VW restorer.

• Round Profile: Features the correct factory "round" shape required to fit inside the torsion housing flange and the spring plate cover.

• Smooth Operation: Reduces friction on the spring plate during vertical travel, which helps maintain consistent rear tire contact with the road.

Technical Specifications

• Part Number: 111-511-245E

• Material: Vulcanized Rubber

• Location: Rear (Left or Right)

• Quantity Required: 2 per vehicle (Outer IRS) or 4 per vehicle (Early Swing Axle)

Installation & Maintenance Tips

• Use Rubber Lubricant: When installing, use a specialized rubber lubricant or a mixture of dish soap and water. Do not use petroleum-based grease, as it will cause the rubber to swell and deteriorate prematurely.

• Inspect the Cover Plate: Check your metal spring plate cover for rust or pitting where it contacts the bushing. A rough surface will chew through a new rubber bushing quickly.

• Proper Alignment: Ensure the bushing is fully seated and not pinched before tightening the four bolts on the cover plate. An improperly seated bushing can cause the rear of the car to sit unevenly.

• Replace in Sets: Even if only one side looks worn, always replace these in pairs (at minimum) to ensure both sides of the car have equal suspension resistance and height.
