🚀 Key Features & Benefits

💪 Cognito Upper Control Arms (UCAs)

Crafted from boxed steel, CNC robot-welded and powder-coated semi-gloss black, these UCAs correct ball joint angles on lifted/leveled applications and improve droop travel for a better ride quality. Each arm includes:

  • Pre-installed heavy-duty ball joints

  • New crush sleeves and polyurethane bushings

  • Maintenance-free performance and superior strength

⚙️ Forged Torsion Bar Keys

Cognito’s forged torsion keys are built to last and level the front end with the rear without overloading factory components. Designed for a precise fit and easy bolt-on install.

🔧 Cognito Pitman & Idler Arm Support Kit (PISK)

The patented Cognito PISK addresses common steering wear issues by reinforcing the pitman and idler arms, eliminating unwanted center-link movement. Result: tighter steering, improved handling, and longer component life—especially important for trucks running larger tires.
