Upgrade your Chevy Silverado or GMC Sierra 1500 (2WD & 4WD) with a complete, no-guesswork leveling kit built around premium Cognito components and FOX Performance Series shocks. Every part is engineered to work together, delivering proper suspension geometry, improved ride quality, and long-term reliability. All Cognito components are engineered, manufactured, and assembled in the USA.

• Cognito SM Series Ball Joint Upper Control Arm Kit

• FOX 2.0 Performance Series Coilover IFP Front Shocks

• FOX 2.0 Performance Series Monotube Rear Shocks

• All required mounting hardware

The Cognito SM Series Ball Joint Upper Control Arms are designed to increase allowable droop travel—critical for a smoother ride and proper suspension function on leveled trucks. By optimizing suspension motion, these control arms reduce harshness, improve handling, and help all components last longer.

Built from boxed sheet metal, these arms are CNC robot welded and finished in a durable semi-gloss black powder coat for strength and corrosion resistance. The kit includes:

• Pre-installed press-in ball joints

• Black anodized, laser-etched Cognito retaining caps

• New crush sleeves and polyurethane pivot bushings

The result is a true bolt-on upgrade that delivers both performance and durability.

Paired with the Cognito control arms are FOX 2.0 Performance Series shocks, engineered to dramatically improve ride quality and control.

• Internal Floating Piston (IFP) prevents oil aeration

• Factory-tuned, precision valving for balanced performance

• Rust-resistant, metal impact extruded aluminum bodies for increased cooling capacity

• Comfortable on-road ride with predictable off-road handling

• Consistent damping under load and rough conditions

• Improved stability, control, and ride comfort

These shocks are easy to install and deliver dependable performance in daily driving, towing, and off-road use.
