Skyjacker's 3- in. Upper Control Arm (UCA) Suspension Lift lets you rise to any occasion. Raising the suspension clearance for 37- in. tires gains ground clearance. Gained ground clearance gives you better approach angles, middle break-over angles and rear departure angles. Retain your Ford tuned performance struts and make good use of the Bronco's impressive travel by utilizing strut spacers to elevate the stance. A 2-piece front strut spacer distributes the lift load more evenly. CNC machined from 6061-T6 Temper Aluminum, the moderate preload Aluminum spacer is the first component to add a higher ride height. Second, is the shorter top mount strut spacer. Skyjacker's replacement UCA's are engineered to withstand extreme amounts of stress and loads. A welded gusset plate stiffens the arm and bushing eyelets into one of rigidity and strength. CNC machined bushing eyelets and ball joint cups ensure precise fitment. The steel encased OEM style rubber bushings deliver a quiet consistent controlled stability and smooth riding comfort. The greasable ball joint's full induction ball design, low friction bearing technology adds longevity and increased strength. Comes preassembled and ready to install with a durable powder coat finish. Proper suspension geometry ensures the Electronic Stability Control (ESC) system functions within OEM parameters. Engineered with built-in caster and camber correction for improved handling and for proper front-end alignment, this system integrates smoothly and functions perfectly allowing the CV axles to operate within limits of the new UCA and OEM lower control arm. The rear 1-piece top mount strut spacer's strong tab and slotted interlocked metal integrity delivers a durable, long lasting product. Precise CNC laser cut and precision formed in CNC press break, they are also powder coated to provide an extremely durable protective barrier to prevent corrosion.
