A 2.0 emulsion coilover is the most basic coilover option for a rock bouncing-style build. It combines the spring and shock into one compact unit, with the oil and nitrogen contained inside the main shock body. For rock bouncing, this setup is best suited for lightweight budget builds, slower trail use, and entry-level buggies that are not being hit hard with repeated throttle climbs, landings, and harsh impacts. It is simple and easy to package, but it has limited damping capacity as vehicle weight, horsepower, and abuse increase.
