An adjustable fluid amplified shock absorber including a casing having a chamber, a piston rod slidable in the casing, a piston head mounted on the piston rod within the chamber, an adjustable channel located between the piston head and piston rod for providing different levels of fluid amplified flow, the adjustable channel being changed in size by axially moving the piston head relative to the piston rod by a threaded connection therebetween, and serrations on the piston head for engagement with grooves on the casing to hold the piston head against rotation while the piston rod is being turned during adjustment.
