510-P1379 | Cognito 3 Inch Elite Billet Upper Control Arm Leveling Kit with King 2.5 Reservoir Shocks For Chevrolet Silverado / GMC Sierra 2500/3500 2WD/4WD

Upgrade your Silverado/Sierra 2500/3500 with a premium leveling system engineered to deliver improved stance, enhanced suspension performance, and exceptional ride quality both on and off road. Designed for 2WD and 4WD applications, this complete package combines high-quality Cognito components with race-inspired King suspension technology to create a system built for daily driving, towing, and demanding off-road use.

Proudly engineered, manufactured, and assembled in the USA, Cognito components are designed to provide dependable performance, precise fitment, and long-term durability without the guesswork.

This leveling kit includes Cognito Billet Upper Control Arms, Torsion Bar Adjuster Keys, the Cognito Pitman and Idler Arm Support Kit (PISK), and front and rear King 2.5-inch Remote Reservoir Compression Adjustable shocks. Together, these components are designed to improve suspension geometry, steering stability, ride comfort, and overall vehicle capability.

The Cognito Billet Upper Control Arms are precision-machined from premium 6061 aluminum and finished in a durable black anodized coating for outstanding strength, corrosion resistance, and long-term durability. Their lightweight yet heavy-duty construction improves suspension geometry and allowable droop travel, making them some of the strongest upper control arms Cognito has developed to date. Every kit includes all required hardware along with a QR code linking to detailed step-by-step installation instructions for a smooth and efficient installation process.

To further improve steering system reliability, the included Cognito Pitman and Idler Arm Support Kit addresses common weaknesses found in factory GM steering systems. Utilizing Cognito’s patented design, the PISK reinforces the pitman and idler arms to help eliminate unwanted center-link movement while improving steering precision, stability, and overall component longevity.

The included King 2.5-inch Remote Reservoir Compression Adjustable shocks deliver a true bolt-on suspension upgrade engineered to elevate both on-road comfort and off-road capability. Developed through extensive real-world testing, these shocks are tuned specifically for your vehicle to provide optimal damping performance, improved control, and exceptional ride quality across a wide range of driving conditions.

Built using the same premium materials, precise tolerances, and race-winning technology found in King’s high-performance competition shocks, these OEM upgrade kits provide the legendary King ride quality in a package designed for everyday use. The system installs with a straightforward 100% bolt-on design requiring no cutting or welding.

Large 2.5-inch shock bodies and external reservoirs dramatically increase oil capacity and heat dissipation to maintain consistent damping performance during aggressive off-road driving, towing, or extended use in harsh conditions. Compression adjustability allows drivers to fine-tune ride characteristics for varying terrain, vehicle loads, and driving preferences, while the fully serviceable design allows future valve adjustments using simple hand tools.

The result is a complete suspension system that enhances the appearance, handling, comfort, and off-road performance of your truck while maintaining excellent drivability and reliability for everyday use.
