C11350 – 3-3.5 in. Component Box With Upper Control Arms

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 and for proper front-end alignment, 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.

Retain your front GM OEM tuned performance shocks by utilizing top mounted Front Shock Extension Brackets. More than simple spacers, these durable 1-piece brackets add strength and integrity to the design.
Replacement forged torsion keys with engineered specific indexing for year split applications are another key feature. These forged keys are stronger than OEM torsion keys and more durable than other cast steel aftermarket keys.

Four (4) separate differential spacers securely reposition correct CV and driveshaft angles.
A 2-inch rear block and u-bolt kit delivers a more level stance.
All the bracketry, components and hardware are contained in this box.
