The Ground Force Kit we got for Godfather's Customs is an all-inclusive tuned suspension package that was put to use in record time, thanks to Godfather's awesome shipping options. The kit features new coil springs that are constructed with the proper wire thickness and spring rate to lower the ride height and improve handling capabilities. These are not just a cut-down version of a stock spring. The shackles and cast-iron blocks are used for the rear because, through hours of testing, Ground Force found out these would work the best without adding undue cost. A complete set of shocks are included, which feature new tuning to keep everything in control in less stroke. When you lower a truck, the components have to work under tighter parameters, and that's why Ground Force builds a whole kit.
