Cognito Motorsports 510-P1393 Ultimate Billet UCA Leveling Kit with Fox FRS 3.0 IBP Shocks 3-Inch

The Cognito Motorsports 510-P1393 Ultimate Billet UCA Leveling Kit is the flagship leveling solution for the 2019–2025 Chevrolet Silverado 1500 and GMC Sierra 1500, including AT4, AT4X, Trail Boss, and ZR2 models in both 2WD and 4WD configurations. This comprehensive kit delivers a 3-inch front lift on standard and Denali models (1-inch lift on AT4, AT4X, Trail Boss, and ZR2) along with an adjustable 1–2-inch rear lift, transforming the stance and performance of your truck from the ground up.

At the heart of this kit is Cognito's Billet SM Series Upper Control Arm (UCA) Kit, engineered to maintain a minimum of 3 inches of suspension droop travel — the critical threshold for preserving ride quality and long-term component durability. The billet upper control arms feature a corrected ball joint angle and high-articulation joint design to optimize front suspension geometry at ride height. Press-in ball joints are pre-installed and retained with black-anodized, Cognito-branded laser-etched caps, while new crush sleeves and polyurethane bushings are included for a complete, ready-to-install assembly.

Paired with the UCAs are Fox Factory Race Series 3.0 Internal Bypass (IBP) Shocks — front and rear — featuring recirculating reservoirs to manage shock oil temperatures under demanding conditions, along with Dual Speed Compression (DSC) adjusters for on-the-fly tuning. The rear of the kit utilizes adjustable-height Deaver mini packs to replace the factory rear leaf springs, allowing fine-tuned stance adjustment.

Key Features:

• Billet SM Series Upper Control Arms with corrected ball joint geometry and high-articulation joints
• Fox Factory Race Series 3.0 IBP front and rear shocks with recirculating reservoirs and Dual Speed Compression (DSC) adjusters
• Adjustable rear lift of 1–2 inches via included Deaver mini packs

Important Notes: This kit requires bypassing the Adaptive Ride Control (ARC) system on 1500 Denali models. Not compatible with trucks equipped with a composite mono-leaf rear spring.
