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, this kit restores proper rear suspension geometry, sharpens handling, and lasts far longer than the factory rubber it replaces.

Vehicle Fitment

• 1968–1978 Volkswagen Beetle (with IRS rear suspension)
• 1971–1979 Volkswagen Super Beetle (with IRS rear suspension)
• 1973–1974 Volkswagen Thing (Type 181)

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

Key Features

• Hyper-Flex polyurethane construction — 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 high-viscosity bushing lubricant for proper installation
• Color: Black

What's in the Kit

Complete set of rear control arm bushings for both left and right sides, plus installation lubricant. Part number 15.3105G, UPC 703639253792.

Why Replace Your Rear Control Arm Bushings?

Worn rear bushings on a Beetle 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 completely collapsed. Upgrading to polyurethane tightens up the rear end and gives the car the responsive feel it had when it left Wolfsburg — only better.

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 are softer than rubber when installed and 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.
