Gas-specific progressive rate Pro-Ride coil springs provide the 6-inch front lift. BDS-engineered lower control arms are longer than stock to rotate the axle for proper alignment, paired with a relocation mounting bracket to flatten the upper control arm angle. Forged drop pitman arm and track bar bracket correct steering geometry. The rear uses progressive rate multi-leaf springs for a 4-inch rear lift with extended U-bolts.
