ReadyLIFT is raising the bar once again for Ford Super Duty suspension performance. The company’s proven 4-inch Coil Spring Lift Systems are now available with all-new Falcon 2.1 Monotube shocks, delivering improved ride quality, enhanced control, and greater confidence whether you’re towing heavy loads, commuting daily, or exploring beyond the pavement. These premium suspension systems are engineered specifically for diesel-powered Ford F-250 and F-350 4WD applications while maintaining the fitment, geometry, and bolt-on installation ReadyLIFT customers have come to expect.
Replacing previous Falcon 1.1-equipped configurations, the new Falcon 2.1 shock package provides improved damping control, greater durability, and enhanced heat management through a larger shock body and oversized hardened shaft design engineered to meet the demands of today’s heavy-duty trucks. The result is a more controlled ride, improved stability underload, and increased confidence both on and off the road.
