Cognito cog110-P1351 3-Inch Performance Leveling Kit with 2.0 IFP Shocks

Front and rear Cognito 2.0 IFP aluminum shocks, rebuildable and tuned specifically for these trucks providing on-road comfort and control with the ability to venture off-road more confidently. Proper length front shocks to maximize suspension travel without binding tie rods, lower ball joints, and cv axles (front suspension droop limiter is the front shock). The specific length of front shock used adds 35% more travel (down/droop travel). To provide consistent damping performance, the shocks are gas charged using the highest quality oil with an Internal Floating Piston (IFP) separating the gas from the oil preventing aeration of the oil that is a characteristic of non-gas charged shocks. A vulcanized upper bar pin and bushing is pressed in the shock end cap to provide OEM like mounting quality. Hard anodized body, end cap, and seal head are used for corrosion resistance.

The Cognito cog110-P1351 3-inch Performance Leveling Kit is designed for 2020–2025 Chevrolet Silverado and GMC Sierra 2500/3500 trucks in 2WD and 4WD configurations. The kit combines Cognito SM Series upper control arms, torsion bar keys, and vehicle-specific front and rear 2.0 IFP aluminum shocks to provide up to 3 inches of front lift while maintaining necessary suspension droop travel.

The rebuildable, gas-charged shocks use an Internal Floating Piston to separate gas from oil and help provide consistent damping performance. Their vehicle-specific tuning is intended to improve on-road comfort and control while supporting more confident off-road driving. The specified front shock length provides 35% more front wheel droop travel than stock and helps maximize suspension travel without binding the tie rods, lower ball joints, or CV axles.

Cognito SM Series upper control arms add caster, correct the ball joint angle, and use the patented high-angle Cognito Alpha Ball Joint. Torsion bar keys provide the desired front ride height and additional clearance for larger tires. The shocks feature hard-anodized bodies, end caps, and seal heads for corrosion resistance, along with a vulcanized upper bar pin and bushing for OEM-like mounting quality. Installation is estimated at 4 to 6 hours, depending on optional add-ons.
