All shock absorbers are not created equal; the Spax brand is often considered the top of the heap! Spax shocks are gas filled for much longer life, and unlike standard oil filled shocks, they are consistent in light to heavy use. The screwdriver adjust feature not only allows you to tailor them to your specific likes, but the ease of adjustment encourages you to change them as often as needed.
