It doesn’t take much lift to get a Super Duty to look impressive! This Cognito 2" Elite 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 Elite package is defined by the Fox 2.5" Factory Race Series shocks which feature a reservoir and DSC adjusters. The adjusters are easy to get to, even in the rear, as we have these shocks built with inverted reservoirs on the rear shocks to make the adjusters easier to get to when you want to crank some compression in for towing a heavy load.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 it 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 Elite kit that is better than stock.
