All the bracketry, components and hardware are contained in this box. Skyjacker fabricated the Replacement Upper Control Arm (UCA) out of high weld strength, thick walled DOM steel tubing to withstand extreme amounts of stress and loads. For additional rigidity and strength, a welded gusset plate stiffens the arm and bushing eyelets into one. CNC machined bushing eyelets and ball joint cups ensure precise fitment. Skilled technicians assemble Skyjacker's exacting CNC laser cutting, bending and machining procedures to our calculated engineering specifications.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 and other technical performance characteristics add longevity and increased strength. Engineered with built-in camber correction for improved handling, this system integrates smoothly and functions perfectly allowing the CV axles to operate within limits of new UCA and OEM lower control arms. The replacement UCA comes completely preassembled and ready to install with a durable powder coat finish.One-piece top mount strut spacers integrate smoothly with the factory suspension geometry. No need to disassemble OEM Struts for install. The strong tab-and-slot interlocked design of the 1-piece top mount strut spacers delivers a strong, long lasting product. Precise CNC laser cut and precision formed in CNC press break, there is expert workmanship in every component of the kit. One-piece top mount strut spacers are powder coated to provide an extremely durable protective barrier to prevent corrosion.Four (4) separate differential spacers securely reposition \ correct CV and driveshaft angles. A 2- in. rear block and u-bolt kit delivers a more level stance. Aligns to OEM factory specifications. Works with Electric Power Assisted Steering (EPAS) system.
