Description
For That Powerful Truck Stance. With the ReadyLIFT 3-Inch SST Suspension Lift Kit, your GMC Sierra 2500 HD will gain a more pronounced presence on the road. The kit increases your truck’s ride height by 3 inches, making it easier to drive through rugged off-road trails and install larger tires. Plus, the added ground gives your vehicle a more powerful stance, enhancing its brawny personality as a result.
Features Heavy-Duty Torsion Keys. This suspension lift kit includes (2) torsion keys. These components boast an industry-leading design and have specific indexing for each application, resulting in a perfect and durable fit for your truck.
Incredible Rear Lift Blocks. The rear blocks in this kit are built from heavy-duty materials, so they won’t break from the weight of your truck. Plus, they’re secured by high-quality U-bolts to prevent them from moving around as you drive across the trails.
Professional Installation Is Required. It’s in your best interest to let a qualified mechanic handle the installation. This is to ensure that each of the kit’s parts is properly secured to your truck. The installation procedure can be completed in no more than 5 hours.
Covered by a 1-Year Limited Lifetime Warranty. This upgrade is backed by a 1-year limited lifetime warranty. This only extends to the original purchaser of the product. Some exclusions apply. Contact or email customer support for more information.
