EZGO's use a truck-style suspension, with leaf springs as the leading suspension point. Yamaha's are leaf-free and use coil-over shocks to support their loads. That is more similar to how a car is set up. These particular golf carts, though, still have EZGO Electric Rear Shocks. They are just not capable of outward resistance. They are dampening shocks. What they are designed to do is slow the travel of the caddie to soften the ride. If you have one break or start leaking fluid, it is time to replace it. You will notice a difference in ride quality as well. If things seem a bit more bouncy, you will know why. Getting the EZGO shock replaced sooner rather than later can save your liver from getting shook loose.This golf cart shock is easy to install. We do recommend having a buddy there, maybe not to help but just for safety. That is a good idea any time you jack up your coach and lay under it. Eight hundred pounds is not fun to have sitting on your arm. Call Buggies Unlimited for a deal on your EZGO parts today.
