Suspension components are key to making sure your car is riding smoothly on or off the road. With upgraded suspension components, you can unlock the full potential of your vehicles performance.
It is recommended that you replace the shocks and struts of your vehicle every 50,000 to 100,000 miles. Replacing your shocks and struts will help reduce your braking distance and improve the overall ride quality of your vehicle. If you are doing some aggressive driving, it is recommended that you upgrade your shocks and struts to a stiffer setup to help enhance the performance of your vehicle.
