Clear up to a 38" tall tire and make your LML/L5P Duramax stand out from the rest with this 10" Performance Lift package from Cognito Motorsports. Cognito has bundled everything you need in this kit so there is no guesswork and you save with the bundled price.

COGNITO BALL JOINT SM SERIES UPPER CONTROL ARMS - The Cognito Ball Joint SM Series Upper Control Arms add style, function and performance to your vehicle by correcting the Ball Joint angle for lifted and leveled applications and improving the allowable droop travel for a better ride quality. The control arm kit features boxed sheet metal arms that are CNC robot welded and powder coated semi-gloss black. Ball joints are included as well as new crush sleeves and polyurethane bushings.

PITMAN AND IDLER ARM SUPPORT KIT - The Cognito Pitman and Idler Arm Support Kit: Pitman and Idler arms have been an inherent wear problem within the steering systems of Chevy and GMC trucks & SUVs for decades. The Cognito PISK (Pitman & Idler Arm Support Kit) replace the problem components that plague factory and aftermarket steering systems on several models and years of GM trucks & SUVs. These improvements are accomplished through application of Cognito's innovative, patented design, by providing additional support to the vehicleโ€™s pitman and idler arms, which eliminate the forward and rearward movement of the center-link.

SWAY BAR - The Cognito HD front sway bar is designed to reduce body roll, so you have better vehicle control and greatly improves traction for safer driving. These HD Sway Bars are developed for this specific application. Measuring 1.5-Inch in diameter and made from heat treated and hot formed 4140 chromoly steel for extra strength and durability. Larger sway bar clamps and polyurethane bushings are included.

FINISH - All steel bracketry is finished in semi-gloss black powder coating.

SHOCKS - The Fox 2.0 Performance Series Remote Reservoir shocks contain the latest in shock technology to transform the performance of your truck. The Fox 2.0 Performance Series IFP front shocks are rust resistant and have a metal impact extruded aluminum body to increase cooling capacity. The IFP eliminates oil aeration allowing maximum performance from the factory-tuned, precision valving. They're easy to install and provide a comfortable on-road ride and predictable off-road handling in even the toughest conditions.

REAR LIFT - The Deaver spring is a complete replacement of the OEM spring, and is arched for 4-Inch over stock rear lift height while maintaining an excellent ride quality via being made from high quality spring steel, a higher leaf count with thinner leaf material for a more compliant ride. The Cognito 3-inch Block and U-Bolt Kit includes 5-inch tall powder coated semi-gloss black steel blocks and heavy-duty zinc plated U-bolts.
