A leveling kit is one of the most popular first mods on a 2007–2013 Silverado/Sierra 1500. It corrects the factory nose-down rake and allows larger tires up front. Here’s everything you need to know.
Why Does the GMT900 Sit Nose-Down from the Factory?
GM engineers the front end to sit slightly lower than the rear to maintain proper stance and handling when the truck is loaded with payload. The typical rake is 1–2 inches front to rear.
Benefits of Leveling:
- Level stance front-to-rear
- Allows up to 33" tires on stock suspension (with some models)
- Better approach angle for off-road
- More aggressive look
Drawbacks:
- Slight reduction in front suspension travel
- May accelerate front upper strut bearing wear on high-mileage trucks
- Alignment required after installation
- Some users notice minor handling changes (minimal with quality kits)
Best Leveling Kit Option:
Rough Country 2" Leveling Kit – 2007–2018 Chevy/GMC 1500 (Part #1307) – The most popular leveling kit for the GMT900 platform. CNC-machined billet aluminum spacers, works with factory struts.
Installation:
- Difficulty: Moderate (requires compressing strut spring or strut removal)
- Time: 2–4 hours with proper tools
- Tools needed: Spring compressor, impact, torque wrench, basic hand tools
- Alignment required after installation
Tire Size with Leveling Kit:
- 2" level on stock suspension: 285/55/20 or 33x12.50 without rubbing on most builds
- For larger tires (35"), you need a full 4" lift
Do You Need New Shocks?
A 2" level does NOT require new shocks. However, if your shocks are worn (over 75K miles), it’s a good time to replace them.
Alignment Settings After Level:
Front alignment changes significantly after leveling. Have a shop set camber, caster, and toe to spec. Budget $80–$120 for a front alignment.
