When the rear suspension starts to go bad, you can usually tell pretty quickly. The back end will scrape along speed bumps and bounce excessively when on rough roads. Any load in the back will also make your Explorer drive with the nose facing up, further making the ride even more dangerous. When your rear end air shocks begin to go bad, replacing them with Suncore's rear air shock replacements will bring the tail end back up to OE standards and maintain a comfortable ride for everyone in the cabin. Suncore's replacements are OE factory style, meaning they will fit directly into your current suspension system and provide you with OE style performance or better.
