Overview:

Built to accommodate 33 tires, this suspension lift system design uses a new spindle engineered to offer the best of all worlds in strength, flexibility, and ease of installation. On 4-wheel drive models, there are two simple cuts to make to clear the front differential and the rest is a bolt on installation. This 4 system comes standard with our revolutionary Pitman/Idler arm support kit that eliminates the premature wear found in the GM pitman and idler arm design that is present even on stock vehicles.

Flexibility to get an extra 2 out of this system is built in, just add the tubular upper control arm kit, turn up the torsion bars or use our replacement torsion bar adjuster keys, and you will be able to run some specific 35 tall wheel and tire combinations including the Hummer H2 take offs. On 4 wheel drive models, the front differential is dropped down a full 4 inches to avoid severe CV axle angles. Other companies only drop the front differential about 75% the amount of the lower control arm, introducing poor CV axle angles.

Strength:

The Cognito lift system comes standard with an incorporated skid plate that doubles as a sub-frame connector. This means that the front and rear crossmembers are connected to create a rigid sub-frame to position the lower control arms and front differential. Many other companies fail to provide some kind of sub-frame connection. With the replacement spindle design, and the upper control arm remaining in the factory location, the control arms are spread further apart by 4 inches. This provides more leverage on the larger wheels thus increasing ball joint life and retaining front-end alignment much better. Lift kits that drop the upper control arm along with everything else are overwhelmed by the added leverage of larger tires, straining upper ball joints and knocking front-end alignments out easily.

Installation:

The new spindle is designed into this kit so that the upper control arm remains in the factory location. This makes for an easier and cleaner installation than a suspension kit that drops the UCA because there are no UCA brackets to install, and the factory bump stop perches do not have to be cut off of the frame as in most kits that relocate the UCA. With a suspension lift system of this height it is unavoidable to cut off the upper mounting ear on the front differential of 4WD vehicles. Since this cut is required, Cognito created a bracket kit to replace this mount if it is ever desired to add that mount back to return the vehicle to stock height, or to change to one of our larger lift systems. There is also one cut to make to the frame, easily made with a reciprocating saw. The rest of the installation is bolt on, as there is no welding required.
