Description
Boost Your Off-Road Game. Before attempting challenging trails you’ve never dared to try before, make sure your Sierra is properly equipped and ready. Consider installing this Cognito Motorsports 4-Inch Standard Suspension Lift Kit on your truck to boost your off-road performance. This complete suspension kit delivers a moderate 4-inch lift that allows you to sport off-road-sized tires.
Fox 2.0 Series Shocks. One of the most important considerations when deciding on a lift kit is the damping performance from elongated shocks. The kit includes a front and rear set of Fox 2.0 series monotube shocks to bring the damping back up to factory levels.
Rear Block and U-Bolt Kit. The burden of the rear lift will be carried out by 1-inch fabricated blocks. Meanwhile, long U-bolts are included secure the bolts on your rear suspension. These are parts made in the USA and reinforced against the elements by high-quality powder coating.
Heavy-Duty Spindles. The spindles included in this kit are fabricated from resilient alloy for durable performance. Their design considers the shift in suspension geometry, bringing back steering performance to OEM level.
Installation Note. If you’re unsure if you can complete the installation of this kit, please leave it to professional installers. This would ensure the best results for your Sierra.
Backed by a Manufacturer's Warranty. Cognito Motorsports provides a generous limited lifetime warranty for this 4-Inch Standard Suspension Lift Kit.

Review shared from Cognito Motorsports Torsion Bar Keys (20-25 Sierra 2500 HD)
2024 AT4 - Sierra2500AT4
Bulletproof craftsmanship
The problem with some of this keys is the manufacturing process and materials used. When this happens the key will not fit properly causing damage to the end of the spring bar. Cognito’s craftsmanship and quality of materials are beyond great. 100% recommended.
