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 aluminum body, end cap, and seal head are used for heat dissipation and corrosion resistance.

• Hard anodized aluminum construction is light weight, dissipates heat faster, and resists corrosion.
• Specifically and only made for leveling application with aftermarket upper control arm.
• Internal Floating Piston (IFP) separating high pressure nitrogen charge from oil.
• Vehicle specific valving for the GM HD trucks providing comfort and control.
• Rear shock length optimized to accommodate stock height up to 1" lift.
• Cognito aluminum 2.0 IFP front and rear shock set.
• Vulcanized upper bar pin mount on front shocks.
