Replace the Coil Springs in your 1999-2003 Ford 7.3L Powerstroke with the proper set for your needs and application. The load capacity of your truck will be increased by a number of the springs available to accommodate items like snowplows and winches. In addition to increased capacity, some coils will lift the front of your truck to give it a leveled stance for a more aggressive look. Eibach and SuperSprings are just some of the top-quality brands you'll find.
