Description
Lifted Stance. Add a commanding, lifted off-road stance to your 2011-2019 2500 HD GMC Sierra by upgrading to an Adjustable Suspension Lift Kit that includes Bilstein 5100 Shocks. With 5 to 6-inches of lift, this kit can accommodate tires up to 35-inches in size allowing you to conquer any trail. This ReadyLIFT Adjustable Suspension Lift Kit features iron steering knuckles, forged torsion keys, rear lift blocks, as well as heavy duty crossmembers and skid plate. What’s more, the included Bilstein 5100 Series Shocks will provide a highly comfortable ride, even across the roughest terrain.
Bilstein 5100 Series Shocks. The included Bilstein 5100 Series Shock Absorbers feature a monotube gas-charged design with velocity-sensitive digressive valving which enhances handling performance off-road while maintaining a smooth yet firm ride on the street. The 46mm shock body is machined from high-grade alloy, offering maximum durability as well as ideal heat dissipation. Likewise, its 14mm piston rod is crafted from chrome-hardened alloy, offering exceptional strength for off-roading. Finally, the shock body is plated in high-quality zinc before receiving a tough clear topcoat for exceptional corrosion protection.
Iron Steering Knuckles. ReadyLIFT includes a set of heavy duty replacement steering knuckles in their Adjustable Suspension Lift Kit. These steering knuckles are manufactured from custom formed nodular iron for superior strength. The knuckles were engineered to provide perfect geometry, ride and handling performance.
Forged Torsion Keys. Vehicle specific lift-oriented ReadyLIFT forged torsion keys provide an adjustable lift while maintaining factory ride quality. These super strong forged torsion keys are much stronger than the stock units with the same design and feature an indexing that is unique to this ReadyLIFT kit.
Rear Lift Blocks. Rear lift is obtained with the use of lift blocks and u-bolts. These OE-style lift blocks are fabricated from cast iron for superior strength. The included longer u-bolts and fasteners allow for a straight forward installation.
Skid Plate and Crossmembers. Both the skid plate and high clearance crossmembers are laser-cut and CNC formed from heavy duty steel plate for superior strength. The skid plate will protect the front differential from rocks and obstacles, while the crossmembers will provide additional strength to the suspension.
Bolt-on Installation. ReadyLIFT designed their Adjustable Suspension Lift Kit to be a straight forward bolt-on install with no cutting or welding required. With all the necessary hardware included, this Lift Kit can be installed in about 12 hours time - professional installation is highly recommended. Please note that an alignment is required after installation.
Application. This ReadyLIFT 5 to 6-Inch Adjustable Suspension Lift Kit with Bilstein Shocks is designed to fit 2011-2019 GMC Sierra 2500 HD models.

2024 Denali - SLINGDING
Installation Time: Full Day
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

Great quality part
This was a 2 in level kit for the front and it was a better quality part than the stock one on the truck, the install was done by myself and done in the driveway. American Trucks have insulation videos on YouTube and made the insulation work a breeze. I would say it’s a 4 hour job all said and done. Had an alignment done right away and it drove nicely, no issues. Very happy with the results.

Simple fix for tire rub
Does exactly what it is supposed to, allows you to upgrade tires and wheels significantly without rubbing ,or sacrificing factory safety equipment. Most importantly opens up a wider variety of of options for custom tire and wheel packages. Relatively painless installation, hardest part is removing original crash bars .

Just installed
So far so good, ride feels great, fit and finished are very nice. Haven’t driven on them very long yet so still reserve full judgement. Also, have not been off-road yet either. But quality seems great and install was very simple.

Easy install
Lift installed relatively easy, I installed it in my garage, instructions were clear and concise. Made my 2022 trail boss sit perfect. my order was on time as usual with AT. I do think the kit is pricey but you get what you pay for. My front end alignment I had done was done with little adjustment by my tire shop, they said the lift was the reason why it was only on the rack 15-20 minutes. Recommend to anyone
