Upgrade your Chevy Silverado or GMC Sierra 2500HD / 3500HD (2WD & 4WD) with a complete, no-guesswork lift kit engineered for strength, ride quality, and long-term reliability. This package bundles premium Cognito components with King Shocks OEM Performance shock upgrades, delivering proper suspension geometry, reinforced steering, and race-proven damping. All 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 improve overall suspension motion—resulting in a smoother ride, better handling, and longer component life.

• Boxed sheet-metal construction

• Fully welded and semi-gloss black powder coated

• Pre-installed, maintenance-free ball joints and pivot bushings

• True bolt-on installation

Pitman and idler arm wear has been a long-standing issue on Chevy and GMC HD steering systems, especially when lifts and larger tires are added. The Cognito Pitman & Idler Arm Support Kit (PISK) solves this problem 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, reduced wear, and significantly increased durability under real-world driving and off-road conditions.

The Cognito 2-inch Block and U-Bolt Kit includes:

• 2-inch-tall cast steel lift blocks

• Durable semi-gloss black powder coat

• Heavy-duty zinc-plated U-bolts for secure clamping

This setup delivers consistent rear ride height while maintaining strength and load-carrying capability.

This kit is completed with King OEM Performance shock upgrade kits, bringing race-winning technology to a daily-driven truck. Each system is extensively tested in real-world conditions to dial in vehicle-specific damping curves and spring rates.

Key performance advantages:

• Large 2.5-inch diameter shock bodies

• External reservoirs for increased fluid capacity and heat dissipation

• Adjustable front ride height

• Up to 25% increase in front wheel travel

• Approximately 15% increase in rear wheel travel

Built with the same materials and tight tolerances as King’s high-end race shocks, these dampers deliver the legendary King ride quality on-road, off-road, and under load. They are also fully serviceable and re-valvable, allowing fine-tuning with simple hand tools.
