These Synergy bump leveling springs are made for 2005 and later Ford F-250 and F-350 Super Duty 4x4 trucks to raise and level the vehicle front-to-rear. Intended as a cost-effective way to restore or set ride height after accessories or load changes, they function as direct-fit replacement springs that alter ride height while preserving Super Duty suspension geometry.
