I admit to not knowing a lot about hydraulic cylinders, but I do know that there are no nitrogen bladders and I am pretty sure that no springs are on the booster used on the Log Boss. I know that it has something to do with a shuttle of some sort, and have seen them put together, but it is not something that I have a lot of knowledge about. As to whether one can be fitted to an existing splitter I don't know. The Log Boss is for lack of a better term, made form scratch. They make the cylinder, the ram, the frame, the rings, everything except the tires and engine. One reason is doing it from scratch allows them to have complete control over the quality of each part of the splitter. If you are using off the shelf components and just assembling them like many companies chances are that a lot of those components are made in China now days. These splitters are 100% made in America, with the possible exception of the tires. JR
