Suncore's Air Suspension compressors are a direct replacement for your vehicle’s OE air compressor. Air Compressors provide air to the integral components of your vehicle’s air ride suspension, keeping air springs and air shocks inflated to a necessary height based on your carrying load, towing and passengers. A properly working air suspension will keep your vehicle’s ride a smoother, more enjoyable one, and help with vehicle stability, braking and fuel economy. Before purchasing a new air suspension compressor, note that the main reason a compressor fails is due to being overworked and burning out, most often caused by a leak in the air suspension, usually in a damaged air spring or air strut.
