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.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eWill 15.3105G fit my Super Beetle?\u003c\/h3\u003e\n\u003cp\u003eYes, as long as your Super Beetle has independent rear suspension (IRS), which all 1971–1979 Super Beetles do.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's the difference between 15.3105G and 15.3105R?\u003c\/h3\u003e\n\u003cp\u003eOnly the color. The \"G\" suffix is black, the \"R\" suffix is red. Material, durometer, and fit are identical.\u003c\/p\u003e\n\n\u003ch3\u003eDoes this fit a swing-axle Beetle?\u003c\/h3\u003e\n\u003cp\u003eNo. This kit is for IRS rear suspension only. Pre-1968 swing-axle Beetles need a different bushing.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need to press these in?\u003c\/h3\u003e\n\u003cp\u003ePolyurethane 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.\u003c\/p\u003e\n\n\u003ch3\u003eHow long do polyurethane bushings last?\u003c\/h3\u003e\n\u003cp\u003eTypically 3–10 years depending on use, often outlasting the rubber originals by a wide margin.\u003c\/p\u003e\n\n\u003ch3\u003eWill these affect ride quality?\u003c\/h3\u003e\n\u003cp\u003eSlightly firmer than fresh rubber, but the difference is small on the rear control arms and well worth the improvement in handling precision.\u003c\/p\u003e\n\n\u003ch2\u003eAbout Energy Suspension\u003c\/h2\u003e\n\u003cp\u003eEnergy Suspension is the worldwide leader in performance polyurethane suspension bushings, with nine U.S. patents and decades of in-house engineering.
