The performance of your built vehicle is paramount, so it's important to pay attention to the inner workings that make it run smoothly. 4 Wheel Parts not only provides specialty products for your four-by-fours, but it also carries all the essentials for its performance. Whether your vehicle is traveling through rough, unpaved roads or soaring through the dunes, you'll want to be able to know that your pressure switch is doing its job. VIAIR Pressure Switches ensure that the compressed air in your suspension is automatically set to the proper PSI, so you can concentrate more on the lift off and less on the landing. Maintenance and Performance Your pressure switch is critical for automatically regulating your suspension. Without it, you would not be able to maintain the proper PSI as it automatically switches on and off so that your suspension has the air compression it needs to function properly. If you begin to notice abnormal sounds or your off-roader riding lower than usual, you'll want to consider if your pressure switch is functioning correctly. 4 Wheel Parts has a selection of VIAIR pressure switches and accessories that can do the job and is available in a variety of PSI so that you can get the right one for your machine.
