Upgrade your GM 2500HD / 3500HD with a complete, no-compromise leveling kit engineered for strength, ride quality, and long-term reliability. This bundle includes everything you need to properly level your truck using premium Cognito components, eliminating guesswork while saving money compared to buying parts individually.

At the core of this system are Cognito SM Series Ball Joint Upper Control Arms, designed specifically for lifted and leveled GM trucks. These control arms correct factory ball joint angles, increase allowable droop travel, and significantly improve ride quality—both on-road and off-road. Proper geometry also reduces stress on suspension components, helping everything last longer and perform as intended.

The boxed sheet-metal arms are fully welded and finished in a durable semi-gloss black powder coat. Each set includes pre-installed, maintenance-free heavy-duty ball joints, polyurethane pivot bushings, and new crush sleeves for a true bolt-on installation.

Cognito forged torsion bar keys provide increased front ride height with unmatched strength. Their forged construction makes them extremely durable, and they install easily using factory mounting locations.

In the rear, the Cognito 1-inch Block and U-Bolt Kit fine-tunes stance and load support. The cast steel blocks are powder coated for corrosion resistance, while the included heavy-duty zinc-plated U-bolts ensure secure clamping and long-term durability.

This kit is finished with FOX 2.0 Performance Series IFP shocks, delivering a major upgrade in ride control and comfort. The internal floating piston (IFP) design prevents oil aeration, maintaining consistent damping and performance. Factory-tuned valving provides a smooth, controlled on-road ride with predictable handling when conditions get rough.
