Sierra 1500 Wheel Spacers: 2025 Ultimate Size Guide for Off-Roaders

Sierra 1500 Wheel Spacers: 2025 Ultimate Size Guide for Off-Roaders

For off-road adventurers, ​wheel spacers solve problems unique to rugged terrain. By pushing wheels outward, they widen the track width, improving grip on uneven surfaces and reducing body roll during sharp turns.

For ​2025 GMC Sierra 1500 owners, spacers also create room for oversized tires or high-performance brake kits—critical upgrades for serious off-roaders. Plus, that “flush stance” isn’t just for show—it translates to better handling.

​Key Benefits of Sierra 1500 Wheel Spacers

1. Enhanced Stability & Handling

Widening the track width lowers your truck’s center of gravity, reducing sway on inclines. For ​GMC Sierra 1500 6x139.7 wheel spacers, this means smoother cornering and fewer fishtailing incidents on loose gravel.

​2. Clearance for Upgrades

Installing ​25mm Sierra 1500 wheel spacers lets you run 33” tires without fender rub or fit massive calipers for improved braking—a must for steep descents.

3. Aesthetic Customization

Achieve the “wide-body” look without costly rim replacements. Spacers push wheels flush with fenders, giving your truck a rugged, purpose-built profile.

4. Compatibility Fixes

Adapt aftermarket wheels to your ​2018 GMC Sierra 1500’s bolt pattern effortlessly. ​The PCD adapters ensure seamless transitions between setups.

Choosing the Right Thickness

Selecting the ideal spacer thickness ensures optimal performance and aesthetics for your ​GMC Sierra 1500. Here’s a breakdown of popular options:

1/2-inch:
Perfect for minor adjustments to eliminate tire rubbing on stock suspensions. Ideal for ​2024 GMC Sierra 1500 owners seeking a subtle, factory-friendly upgrade.

1-inch: 
Balances stance and functionality, clearing space for larger brakes while maintaining a low-profile look. Great for daily-driven trucks that occasionally tackle trails.

1.25-inch:
Offers a more aggressive stance without compromising drivability. Works well with ​2022 GMC Sierra 1500 models running 33” tires and mild lifts.

1.5-inch: 
A crowd favorite for off-roaders, this thickness pairs perfectly with mid-sized lifts and 35” tires. 

2-inch: 
Maximizes track width for rock-crawling stability. Unmatched durability in desert or mountain terrain.

​3-inch: 
Built for extreme setups, these spacers accommodate massive 40” tires and reinforce load distribution.

Each thickness is engineered to match ​GMC Sierra 1500 6x139.7 wheel spacers bolt patterns, ensuring a hub-centric fit that maintains alignment.

For lifted trucks, thicker spacers (1.5”+) counterbalance height gains, while slimmer options (15mm-30mm) prioritize daily usability. Always pair your spacer choice with proper suspension upgrades for seamless integration.

Why BONOSS Stands Out?

1. Forged Active Cooling Design

Unlike cast spacers, ​BONOSS forged active cooling wheel spacers are CNC-machined from aerospace-grade aluminum.  The integrated cooling grooves help brake heat dissipation, ensuring longevity.

2. Precision Hub-Centric Fit

BONOSS forged hub-centric wheel spacers match your Sierra’s factory specs down to the micron. This eliminates vibrations at high speeds and distributes load evenly—critical for avoiding stud failures on rough terrain.

3. Rigorous Safety Testing

Every spacer undergoes 10+ stress tests, including tensile strength and salt spray corrosion trials. For ​2024 GMC Sierra 1500 owners, this means peace of mind when pushing limits.

​4. Plug-and-Play Installation

BONOSS kits include corrosion-resistant studs and lug nuts, so you won’t need extra parts. Their ​hub-centric design also means no alignment adjustments—just bolt on and go.

Installation Made Simple

  1. Lift the truck and remove wheels.
  2. Clean the hub surface thoroughly.
  3. Mount the ​BONOSS spacer using included hardware (torque to 90-100 lb-ft).
  4. Reinstall wheels and torque lug nuts to factory specs.
  5. Pro Tip: Use a thread locker for added security on rocky trails.
