It doesn’t take much lift to get a Super Duty to look impressive! This Cognito 2" Performance Leveling Kit has all the components to do just that. Leveling the stance only requires 2" of lift up front, and then up to 37" tires will fit and fill up the fender wells proportionately. The Cognito coil springs are dual rate, slightly softer than stock with a progressive rate as they compress, replacing the OEM single rate springs and providing 2" of lift. When you lift a solid axle truck, the track bar angle increases, and since the OEM track bar is fixed in length, the axle is shifted toward the left side of the truck. This Cognito package includes a heavy-duty, adjustable-length track bar assembly to provide a long-lasting durable track bar that is also adjustable to get the front axle centered under the frame at ride height.This Performance package is defined by the Fox 2.0 Perfromance Series IFP shocks. These shocks are the most popular on the market in this price range, perform much better than the OEM shocks, and look much better also.37" tires fit nicely, since we are talking about a dually here, you will want to refer to the wheel manufacturer of your choice for proper width and back spacing, be sure to have chosen the tire brand, model, and size you are going to use before contacting the wheel company. If you choose to use stock wheels, you will want to stay with a narrow tire, or decide to use a wheel spacer up front, and also in between the rear wheels to keep the rear tires from touching each other. You want your truck to ride as good as stock, how about better than stock? Make sure you choose a quality name brand tire with the appropriate load rating, and you will enjoy a ride quality with this Cognito Performance kit that is better than stock.

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

For model years 2011–2014 and most of 2015, GM included OEM provisions for a steering stabilizer, requiring two mounting points: one on the right side of the steering center link and one on the left side of the frame. All 2011+ models retain the center link mounting provision—a tapered hole near the idler arm. However, only 2011–2014 and select 2015 trucks came with the frame-side mounting clevis (two welded tabs on the crossmember). This OEM clevis interferes with the Cognito bracket and must be removed if present, as the included FOX stabilizer is not compatible with the factory mounting location.

• 2011-2015 model years require cutting off of the OEM frame clevis with tabs
• Compatible with lift kits that have the center link in the factory location
• Simple and completely bolt on installation for 2016+ model years
• Compatible with the Cognito Pitman and Idler Arm Support Kit
• Reduce feedback from the road through the steering wheel
