Making sure everything on your golf cart gets upgraded can be a difficult task. Leaving no stone unturned in a rock quarry would be an easier task to accomplish. Forgetting to change parts like the E-Z-GO Heavy Duty Rear Spring U-Bolt and leaving the standard ones in place can be a big mistake. Most of us do not use our golf carts for golf. Everything else that we could possibly think up to throw them at is more our style. We use them for hunting and getting out in nature. We have customers and family who use them on the job site. These adventures call for much more aggressive parts than what you need to cruise around the links. Make sure you are covered for the task at hand.A golf cart u-bolt is used to secure the leaf springs in the rear. Depending on the setup, you may need up to four or as little as two. Before you order, stick your head under the cart and make sure. Then call buggies Unlimited.
