Using these shocks is easy. First, make sure your vehicle is one of the compatible models listed. When installing, follow the provided instructions carefully. These shocks are great for both on - road and off - road driving. For on - road, you'll notice a much more comfortable ride, and off - road, they'll give you better control. Remember, these shocks won't fit 2004 models, so double - check your vehicle year. To maintain them, keep an eye on the aluminum body. Since it dissipates heat faster, it's important to make sure there's no damage that could affect its heat - dissipation ability.
