MagneRide shocks are a type of adaptive suspension that uses magnetorheological fluid to adjust the stiffness of the suspension. This allows for a more comfortable ride over bumps and other irregularities in the road. The downside to this technology is that it is more expensive than traditional shocks, and it is not clear how long they will last.
It is difficult to say how long MagneRide shocks will last because they have only been on the market for a few years. However, there have been some reports of them lasting for over 50,000 miles. With proper maintenance, they should be able to last even longer. If you are considering buying a car with MagneRide shocks, be sure to ask the dealer about the warranty and service plans that are available.
