This new system is perfect for the F250 owner looking for a 2.5" lifted and leveled stance with the performance of dual rate coil springs. This kit is complete with new front dual rate coils, brake line relocation brackets, turnbuckle style adjustable front track bar, ball joint cams, coil shims, rear replacement block kit and your choice of shocks.
The key to this kit is the coil seat correction shims and upper ball joint cams. The coil seat shims reposition the lower seat to be square with the frame mount to minimize coil bow which is typical of leveled F250/F350 trucks when the radius arms aren't relocated or replaced. The ball joint cams return the caster to factory settings to provide stock-like handling and drivability.
