Upgrade your 2020–2024 Chevy Silverado or GMC Sierra 2500HD / 3500HD (2WD & 4WD) with a complete, no-guesswork leveling kit built around premium Cognito components and FOX Performance Elite shocks. Every component in this bundle is engineered to work together, delivering proper suspension geometry, improved ride quality, stronger steering, and race-proven shock performance. Cognito components are engineered, manufactured, and assembled in the USA.

The Cognito SM Series Ball Joint Upper Control Arms are designed specifically for lifted and leveled GM HD trucks. They correct factory ball joint angles, increase allowable droop travel, and ensure proper suspension motion—resulting in smoother ride quality, improved handling, and longer component life.

These control arms feature boxed sheet-metal construction, CNC robot welding, and a durable semi-gloss black powder coat. Each kit includes heavy-duty ball joints, polyurethane pivot bushings, and new crush sleeves for a true bolt-on installation. Increased droop travel is critical for optimal ride quality and ensures all suspension components function as intended.

Cognito forged torsion bar keys level the front of the truck to match the rear while maintaining factory reliability. Their forged construction makes them exceptionally strong, and they bolt directly into factory mounting locations for an easy, hassle-free install.

Pitman and idler arm wear has long been a weak point in Chevy and GMC HD steering systems, especially when larger tires and suspension upgrades are added. The Cognito PISK (Pitman & Idler Arm Support Kit) solves this issue using Cognito’s patented design, providing additional support to the pitman and idler arms and eliminating forward and rearward center-link movement. The result is improved steering precision, durability, and long-term reliability.

This kit is finished with FOX Performance Elite Series 2.5-inch smooth-body reservoir shocks, delivering race-proven technology in a bolt-on package. Derived directly from FOX off-road race shocks, these dampers are tested in brutal conditions far beyond typical street or trail use.

Key features include:

• External compression adjusters for quick tuning

• Improved on-road comfort and high-speed stability

• Increased control and confidence off pavement

• Excellent heat dissipation for consistent performance under load

With the turn of a knob, you can fine-tune the shocks for changing terrain, towing, or added weight—giving you complete control whether you’re carving pavement or tackling rough trails.
