Leveling your 2014–2018 K2XX Silverado or Sierra is one of the most popular first mods — removes the factory rake, allows larger tires, and improves the stance with a bolt-on install. Here’s what to know before you buy.
What is a Leveling Kit?
The K2XX from the factory sits lower in the front than the rear (this is called “rake”) by about 1.5"–2". A leveling kit adds spacers on top of the front struts to bring the nose up to match the rear.
Typical leveling kits: 1.5" to 2.5" front lift only.
Types of Leveling Kits
Strut Spacers (Most Common)
Billet aluminum spacers that sit between the top of the strut and the strut tower. Simple, effective, reversible.
- Pros: Easy install (2–3 hours DIY), inexpensive ($40–$120), no geometry changes on minor lifts
- Cons: Very large spacers (2.5"+) can slightly change strut angle; buy quality — cheap spacers can crack
Strut Extension Plates
Similar to spacers but mount differently; some brands offer an extended plate that bolts into the OEM strut holes.
What Fits After a Leveling Kit?
| Leveling Amount | Stock Tire | Max Tire (No Trimming) |
|---|---|---|
| Stock (no lift) | 265/60R20 | 265/70R17 or 275/55R20 |
| 1.5"–2" level | 265/70R17 | 285/70R17 |
| 2.5" level | 285/70R17 | 295/70R17 (may need backspace check) |
Check your specific wheel offset before going to 285s+ — backspacing matters.
Recommended Kit
The Rough Country 1307 1.5"–2" Leveling Kit for K2XX is one of the most proven options for the 2014–2018 platform — billet strut spacers, hardware included, straightforward install.
Install Overview
- Lift vehicle and support on jack stands
- Remove front wheel
- Compress the strut spring (spring compressor required for full strut removal)
- Remove the three top strut nuts at the strut tower
- Install spacer on top of the strut assembly
- Reinstall strut, torque to spec
- Repeat opposite side
- Get an alignment after install — critical to avoid uneven tire wear
Important Notes
- Alignment is mandatory after any leveling kit — do not skip this
- Leveling kits will use up some of your front suspension travel — this is normal
- On Z71 trucks (with factory Rancho shocks), a 2.5"+ spacer may start to compress the shock beyond its design range; a shock replacement may be recommended
