Simply put, shock absorbers serve as a cushion to resist the up-and-down motion of a vehicle as it rolls down an uneven and often bumpy roadway. A variety of shock absorbers exist for different load conditions. Heavy-duty shocks are larger than standard shocks and have more fluid, which means they can handle heavier loads, but in doing so, offer a more turbulent ride. These are best for vehicles that frequently carry or tow heavy loads. Gas-powered shocks are a recent innovation which prevent shock absorber 'fading,' the temporary inefficiency of normal shocks when suddenly confronted with excessively rough terrain. Many newer vehicles are now equipped with gas-powered shocks as standard equipment. Another type, the variable load shock absorber, is designed for vehicles that carry different weights at different times. It responds differently to various weights through the use of electronic or mechanical sensors in an effort to give riders the smoothest possible ride under any driving conditions. To keep your shocks in good condition, have them replaced after the vehicle's first 25,000 miles and every 15,000 miles thereafter.
