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.

Pretty solid kit!!!!
Kit definitely clears my 35x12.50 r20 tires and rims with a negative 12 offset wheel. Did have to do a little bit of trimming around the the plastic mud flaps. Only major issues I had was the kit says to use your stock an arm bolts. My stock an arm bolts are 5/8 thick in diameter. The an arms that were supposed to fit were only 1/2 inch. All in all the kit provides decent clearance and not too difficult to install. I’m wondering since my truck is a 2024 if they changed the factory bolt size to 5/8 inch from 1/2 inch on the 2023s. Ride quality is pretty solid. I got the torsion bars dialed in right at 27 1/2 inches which is the max distance for the kit to handle and the bumb stops have a little bit of clearance making it ride a bit smoother

Make shure its right
I ordered this kit for my cab and chasis dodge 3500 the front worked great everything fit but when it came to the rear the u bolts were not right as mine were square, bolted different since i have the helper spring and i had a larger than normal leaf pack so i had to pay $159 for 4 custom u bolts other than that its a nice kit and worked well
