What are the ford f150 coil spring dimensions?

The coil springs on a Ford F-150 vary depending on the year and trim options that You select. They can also change based on the gear ratio that You have in the rear differential. A gear ratio that is designed to tow more will have larger springs than one that is designed for highway driving. The best way to determine the spring size on Your truck is to go inspect it with a tape measure because You will need to get the same size springs to keep the factory ride. Typically they are 12 inches long to 16.9 inches long depending on all the options. Larger springs can also be used with new shocks to help raise Your truck if You want more ground clearance for going off road.
