As with most other automotive components, there is no simple answer to how long shock absorbers may last. This is because their lifespan depends on several factors, including driving habits and prevailing road conditions. Tires themselves are something to consider, too, as improperly balanced ones may cause premature failure of the corresponding shock absorber. Under normal running conditions, most shock absorbers will last anywhere between 50,000 and 100,000 miles. To be on the safe side, owners should check their condition and test their performance once a year.
