King Shocks is a manufacturer and servicer of custom made adjustable and rebuildable automotive shock absorbers and performance racing products for utility vehicles, OEM replacement and professional racing use. The company prides itself on putting quality, performance and customer service above all else. Every product we sell is the result of constant testing and development done with top racers in competition worldwide. This real world testing exposes our designs to a level of abuse and destructive forces that cannot be duplicated in a laboratory. In addition to our busy field-testing schedule, preliminary designs are quantified using our state of the art, electro-magnetic, shock dyno capable of inducing shaft speeds up to 120 inches per second with a drive position resolution of 1 micron. It can play back racecourse data collected from a number of commonly used onboard, automotive data acquisition systems and uses a non-contacting Infrared style transducer to monitor temperature readings. It's the closest thing to real world conditions without getting sand in your shoes.

Q: Can these be installed on the shock after the shock has been installed on the vehicle?  Answer this question

A: The guards should be able to install on shock while on installed on vehicle. Shaft Guards are available for all 2.5 smoothie shocks with threaded aluminum rod ends, 2.5 shocks with welded rod ends or 2.5 shocks with pin shafts. Older shocks will need new rod ends or shaft assemblies to accept King's new Shaft Guards.
