GMC Sierra 2500 HD and 3500 HD Leveling Kits: How to Choose
Share
This guide is for owners of a GMC Sierra 2500 HD or 3500 HD who want to take out the factory nose-down stance. A leveling kit raises the front to match the factory rear height, without changing the rear suspension. Choose by model year first, then check that the kit names your model and trim, then pick the lift height and what comes in the box.
What to check first on a Sierra HD
- Model year. The kit titles below read 2001-2010, 2011-2019 or 2020-2026. Our Sierra HD pages are Leveling Kits for 2007-2014 GMC Sierra 2500/3500 HD and Leveling Kits for 2015-2019 GMC Sierra 2500/3500 HD. For a 2020 or newer truck, use the vehicle selector on Truck Leveling Kits.
- 2500 HD or 3500 HD. Most titles here name both. The Rough Country 2020-2026 title names only the 2500HD and the ReadyLift 66-3050 title names the 2500 HD "and more", so 3500 HD owners should buy only a kit whose title or fitment table lists the 3500 HD.
- Trim. A title can exclude trims: the Rough Country 2020-2026 kit excludes the AT4X. The ReadyLift fitment tables list the trims each kit covers, year by year, so check yours there.
- Alignment and tires. An alignment afterwards is normal, and larger tires may need trimming.

The ReadyLift Suspension Leveling Kit, 2" Lift (66-30321) is titled for 2020-2026 Chevrolet Silverado 2500 HD / 3500 HD and GMC Sierra 2500 HD / 3500 HD. ReadyLift says its 2 inches of lift reduce the factory nose-down stance. It and the 66-30200 are both 2" ReadyLift kits titled for the same 2020-2026 trucks; the titles do not say how they differ, so compare the two product pages.

FAQ
Does a leveling kit change the rear of my Sierra HD?
No. A leveling kit raises the front to match the factory rear height, without changing the rear suspension.
Will I need an alignment after leveling?
Expect one: an alignment afterwards is normal, and larger tires may need trimming. Follow the instructions on each product page.
Does the Rough Country 2020-2026 kit fit a 3500 HD or an AT4X?
Its title names the 2020-2026 Silverado/Sierra 2500HD and excludes the AT4X and ZR2. For a 2020-2026 3500 HD, the ReadyLift 66-30200 and 66-30321 titles name it.
Which kits include shocks?
Both Rough Country titles say N3 shocks are included. The ReadyLift descriptions here do not list shocks; check the product page.
