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 Note: This kit fits IRS-equipped models only. Swing-axle Beetles use a different bushing. Why Choose Energy Suspension? Energy Suspension is the worldwide leader in performance polyurethane suspension bushings, with nine U.S. patents and decades of in-house engineering. Every Hyper-Flex component is performance-tested and race-proven. Key Features & Benefits Hyper-Flex polyurethane: Resists oil, road salt, and contaminants that destroy rubber bushings. Full-floating, non-binding design: For smooth suspension travel. Maintains correct rear alignment: Under cornering, towing, and hard driving. Drops into the factory control arms: No modifications required; reuses OE shims. Includes bushing lubricant: High-viscosity lube for proper installation. Technical Specifications Material: Hyper-Flex performance polyurethane Color: Black Fits: Rear control arms, left and right Includes: Complete bushing set plus installation lubricant Part Number: 15.3105G UPC: 703639253792 Manufacturer: Energy Suspension 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.
