It's not all that impressive, in fact, it's not really even my idea...........................,but anyway its basically a piece of solid bar that slides inside a bit larger piece of tubing. Then, you fasten some rubber to the end of the bar and drill holes to suit your valving needs. After that, fill the tube with grease and assemble. As long as you do not over extend your new shock absorber it will work well enough to start and a finish a few SAE Mini Baja events. Fine tuning can be done with grease viscosity, but it is alot easier to poke more holes in or plug up holes in your "piston."
A couple of fun trivia questions on this topic:
1.) What was the first automotive application for a grease-draulic shock absorber?
2.) What is the most well know vehicle to use this type of shock absorber?
3.) What is a modern day, common application for this shock absorber?
