Energy Suspension 15.3105G Rear Control Arm Bushing Kit — Hyper-Flex Polyurethane for VW IRS

The Energy Suspension 15.3105G is a complete polyurethane rear control arm bushing kit engineered to replace the worn, sagging rubber bushings on your air-cooled VW's independent rear suspension (IRS). Made from Energy's Hyper-Flex performance polyurethane, it restores proper rear suspension geometry, sharpens handling, and lasts far longer than the factory rubber it replaces.

Worn rear bushings cause clunking over bumps, vague rear-end feel, uneven tire wear, and rear toe changes during cornering. After 40+ years, original rubber bushings are almost always cracked, oil-soaked, or collapsed — upgrading to polyurethane tightens up the rear end and restores responsive handling.

Vehicle Fitment

• VW Beetle (IRS): 1968–1978
• VW Super Beetle (IRS): 1971–1979
• VW Thing (Type 181): 1973–1974
• VW Karmann Ghia (IRS): 1968–1974

Note: This kit fits IRS-equipped models only. Swing-axle Beetles use a different bushing.

Frequently Asked Questions

• Will 15.3105G fit my Super Beetle? Yes, as long as your Super Beetle has independent rear suspension (IRS), which all 1971–1979 Super Beetles do.
• What's the difference between 15.3105G and 15.3105R? Only the color. The "G" suffix is black, the "R" suffix is red. Material, durometer, and fit are identical.
• Does this fit a swing-axle Beetle? No. This kit is for IRS rear suspension only. Pre-1968 swing-axle Beetles need a different bushing.
• Do I need to press these in? Polyurethane bushings typically slide into the control arm housings with the supplied lubricant. A press is not usually required, though a vise or careful tapping helps.
• How long do polyurethane bushings last? Typically 3–10 years depending on use, often outlasting the rubber originals by a wide margin.
• Will these affect ride quality? Slightly firmer than fresh rubber, but the difference is small on the rear control arms and well worth the improvement in handling precision.
• What is the part number? Energy Suspension 15.3105G (black). The same kit in red is 15.3105R. UPC 703639253792.
