Ride Quality Meets Control with Non-Torsion Bar Drop Design

Unlike traditional high-lift kits, Cognito’s Non-Torsion Bar Drop design preserves ground clearance and CV joint angles, helping prevent premature wear and vibration. This innovative geometry maintains proper droop travel, ensuring a compliant ride whether you’re loaded down, towing, or traversing rough terrain. All components are engineered, manufactured, and assembled in the USA for unmatched quality control and consistency.

FOX 2.0 Performance Series IFP Shocks: Proven Technology

Included in this system are FOX 2.0 Performance Series IFP Monotube shocks, front and rear. These shocks feature a metal impact-extruded aluminum body to resist rust and improve heat dissipation. Inside, the Internal Floating Piston separates the nitrogen-charged gas chamber from the oil, eliminating aeration and maximizing shock performance. Whether you're tackling trails or cruising highways, these shocks deliver a smooth, confident ride.

Rear Lift and Heavy-Duty Components

The rear setup includes a Cognito 2-Inch Block and U-Bolt Kit with powder-coated semi-gloss black cast steel blocks and heavy-duty zinc-plated U-bolts. Together, they level out the rear stance and provide the strength needed to handle towing, payload, and real-world off-road abuse.
