Cognito Motorsports 110-91399 Billet Upper Control Arm Kit with Delta Joint for 2019-2025 Silverado/Sierra 1500

The Cognito Motorsports 110-91399 Billet Upper Control Arm Kit with Delta Joint is a premium front suspension upgrade engineered for the 2019–2025 Chevrolet Silverado 1500 and GMC Sierra 1500 (2WD/4WD), including AT4, AT4X, Trail Boss, and ZR2 models. Designed for lifted and leveled applications, this kit restores proper suspension geometry and maximizes droop travel for improved ride quality both on and off the road.

Key Features:

• CNC-machined billet aluminum upper control arm construction for superior strength and reduced weight compared to OEM stamped steel arms
• Includes a Delta Joint — a high-articulation, rebuildable ball joint designed to handle the extreme angles encountered with lifted and leveled applications
• Corrects ball joint angle and caster geometry for leveled and lifted trucks, reducing binding and improving steering feel
• Increases allowable suspension droop travel for better wheel articulation and off-road capability
• Slightly increases caster angle for improved high-speed stability and highway drivability
• Powder-coated finish for long-lasting corrosion resistance
• Direct bolt-on installation — no cutting, drilling, or welding required
• Compatible with 2WD and 4WD configurations, including AT4, AT4X, Trail Boss, and ZR2 trim levels

This kit includes the driver and passenger side billet upper control arms, Delta Joint hardware, pivot bushings, crush sleeves, and all necessary installation hardware. The Cognito 110-91399 is an ideal solution for truck owners running a leveling kit or suspension lift who want to eliminate premature ball joint wear, restore factory-like ride quality, and add long-term durability to their front suspension system.
