# Skyjacker 3-3.5In KIT 20 GM 2500HD/3500

Conquer your daily driving adventures and tough off-road terrains with new control. Whether you are getting work done or towing to your next outdoor adventure, Skyjackers fully bolt-on 3.5-inch Lift with Replacement Upper Control Arms (UCA) goes beyond just styling into On-Road Refinement and Off-Road Readiness. Skyjacker fabricated the replacement UCA out of high weld strength, thick walled DOM steel tubing with welded gusset plates to stiffen the arm and bushing eyelets into one. 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. Engineered with built-in camber correction for improved handling and for proper front-end alignment. Aligns to OEM factory specifications. Electric Stability Control (ESC) system functions within factory parameters. UCA comes preassembled. Retain your front GM OEM tuned performance shocks by utilizing a unique 1-piece top mount 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 relieve OEM component strains. These forged keys are stronger than OEM torsion keys and more durable than 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. Complete with mounting hardware. Shocks are a key link in-between the chassis and your suspension. Rear damper capacity enhanced with ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks. ADX 2.0 has a race-inspired full-displaced valving system. Nitrogen charged with Internal Floating Piston Technology = Quickest Shock Reaction Time Ever.
