Review on Enhance Performance with KYB KG5551 Gas-a-Just Gas Shock for Superior Handling by Ryan Turner

KYB is a well known brand. They should last longer than a car. The gas pressure is quite strong, I couldn't squeeze them without squeezing with both hands. In this case you need to move the axle up and down to align the screw hole at the bottom. The only drawback was that the upper eyelets are not as thick as the original. I reused the originals as they better isolate the shock from the body.
