Since most buggies are VW based most of them have either king / link pin or ball joint front beams. These cars are often referred to as “beam cars”. There are also cars with A-arm front suspension. We will discuss those later. The quick easy way to identify which style of front beam you have is to see how the top of the front shock mount. If the bolt goes through the top of the shock horizontally it is king / link pin. See below.
If the top of the shock bolt goes up through the top and has a nut on it that would be ball joint. See below.
