We have bundled everything you need in a leveling kit for your Silverado/Sierra 2500/3500 2WD/4WD with high quality Cognito components and Fox shocks.

There is no guesswork. Cognito components are engineered, manufactured and assembled in the USA. This kit includes the Cognito Ball Joint SM Series Upper Control Arm Kit, Torsion Bar Adjuster Keys, Cognito Pitman and Idler Arm Support Kit, front and rear Fox Performance Series Remote Reservoir shocks and front shock spacers to maximize droop travel.

The Cognito Ball Joint SM Series Upper Control Arms feature boxed sheet metal arms that are welded, and powder coated semi-gloss black. Pre-installed maintenance free ball joints and pivot bushings are included.

The Cognito Ball Joint SM Series Upper Control Arms adds performance to the Chevy and GMC truck by correcting the ball joint angle for lifted and leveled applications, increasing droop travel, and increasing caster slightly for better highway speed drivability.

The Cognito PISK (Pitman and Idler Arm Support Kit) replaces 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.

Fox 2.0 Performance Series Remote Reservoir smooth body shock delivers FOX's industry leading and race dominating performance in an affordable, hassle-free bolt on package. Its external reservoir allows for increase oil and nitrogen capacity while delivering striking race look.

The race developed high flow damping piston matched with application specific valving provides the 2.0 Performance Series Reservoir shock a predictable ride quality capable of handling the roughest road conditions.

Product Questions
Will this work on a 2023 GMC 2500 AT4?
Hi Scott, Yes! all our leveling kits for that truck are compatible with the AT4 trim for model years 2020-2023.
With this kit, can I run a 20inch wheel and a 35 tire?
Hi Doug, Yes, you just have to be selective about the wheel and tire combination to avoid contact with the control arm or a bunch of body rubbing that will require trimming.
Will the factory wheels fit?
Hi Kevin, Yes, but you will have to be selective of your tire choice because the tire cannot be wider than stock without using a small wheel spacer.
Are these balljoints removable?
Hi, Yes, all of our ball joints are removable and replaceable.
Will this kit also work on the new 2024 GMC 2500HD Denali?
Hi James, We are in the process of verifying 2024 fitments. We are hoping to be finished next week.
Will this level kit prohibit me from running on 4wd Auto? I have a GMC 2024 2500HD AT4. Thank you!
Hi Diego, No, it will not impact any of your 4WD operations. You can use your 4WD as you would stock.
Will this ki clear 37s?
Hi Theo, It's been done, but it will require a notable amount of trimming and a conservative wheel and tire combination.
With this kit can I run 20 x10 Methods with a -18 offset on 35x12.50 R20
Hi Mike, That wheel and tire combination will fit, but a fair amount of trimming will be involved to clear when turning.
What type of 5 inch space is required for the wheel and tire fitment?
Hi Hunter, The 5" backspacing referred to in the product description is the amount of wheel from the mounting surface to the inner edge of the wheel. Please see the image below for reference.
Does the remote reservoir Fox 2.0 shocks provide a nicer than stock ride on the 2500. I purchased them for my 1500, gave me a ruff ride.
Hi Joe, Yes, we always see a much better ride on these shocks. Especially of the OEM shocks have more than 25k miles on them. Something to keep in mind is, ride height will also impact ride quality. If the ride height is too high, the ride will be...
Is this lift reversible (can you return the truck back to factory height)?
You can definitely bring the truck back to stock height with stock components reinstalled (arms, shocks, keys).
