Mostly, the 4×4 wheel spacers are reliable wheel accessories which stop tires from rubbing, clear brake caliper interference, improve the appearance, enhance the handling of swerving, and more. They are machined to your vehicle specification, which ensures perfect fitment. A perfect fitment brings a snug wheel connection.
Selecting the right 4×4 wheel spacer size is a personal decision based on your preferences and actual modification. For example, if you have replaced the stock wheels to high-offset wheels or you have added a lift kit, you might notice that 10mm spacers are not enough to clear the rubbing issues.

Best 4×4 Wheel Spacers Sizes Chart
There are 1/2-inch to 2-inch wheel spacers available for your 4×4 rig. Here are the pros and cons of these sizes:
- 1/2-inch: Good option for those who just need a little bit of wheel clearance to fit bigger brake calipers. These thin spacers provide an OEM-like handling.
- 1-inch to 1.25-inch: A good start for those seeking a perfect flush wheel stance. These modest wheel spacers allow for larger tires without rubbing.
- 1.5-inch to 1.75-inch: Popular 4×4 wheel spacer sizes among off-roading enthusiasts looking for a bolder, more aggressive look. They provide more stability while cornering.
- 2-inch to 3-inch: Ideal for serious modification enthusiasts who need the extra clearance to fit a wide-body kit. To ensure safety, always choose a high-quality hub-centric set.
4×4 Wheel Spacers Installation Tips
- Make sure the bolt thread is clean and dry with no oil or grease.
- Use the torque wrench to tighten wheel lug nuts in a crisscross sequence.
- It is crucial to re-torque your new wheel spacers after the first 50 to 100 driving miles.

Why BONOSS 4×4 Wheel Spacers Stands Out?
When selecting the best 4×4 wheel spacers, BONOSS excels in safety and performance. With the advanced technology and unmatched quality, BONOSS offers several key advantages that make their spacers a top choice.
1. Useful Active Cooling Function
With the same price as most rim spacers, BONOSS forged active cooling 4×4 wheel spacers provide an active cooling function. Distributed in petal shape, these grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates.
The air takes away the heat to actively dissipate heat for the brakes. Such BONOSS forged active cooling 4×4 spacers improve the cooling efficiency, reducing brake thermal decay, and improving road safety.
2. Aerospace-grade Aluminum Materials
All BONOSS forged active cooling 4×4 wheel spacers are made of forged 6061-T6 or 7075-T6 billet aluminum alloy. The tensile strength is up to 572 MPa and the yield strength is up to 503 MPa (as strong as aviation aircraft). High tensile strength gives it strong resistance to being pulled apart, making it resistant to bending and breaking.
3. Optimized Hub-centric Design
What’s better, BONOSS forged active cooling 4×4 wheel spacers come with multi-stage hub-centric rings. The hub-centric metal ring is machined to be multi-layers, and the bevels fit for the corresponding hub flange, which eliminates any possible gaps. These BONOSS 4×4 wheel spacers make a snug connection between the wheel and vehicle hub, reducing the chances of vibrations.
Frequently Asked FAQ
Q: Do I need 4×4 wheel spacers for a lift kit?
A: Yes, for those who would like to add lift kits while keeping the stock wheels, using 2-inch spacers is a good idea.
Q: Do 4×4 wheel spacers break studs?
A: No, properly torquing high-quality wheel spacers, there will be no problems.
Q: Do 4×4 wheel spacers rust?
A: Quality brand (like BONOSS) aluminum wheel spacers won’t rust even after a long time.
Final Verdict: Upgrade Your Car with BONOSS
From innovative active cooling benefits to certified materials and precise manufacturing, BONOSS forged active cooling 4×4 wheel spacers are engineered to enhance your driving experience with safety, strength, and reliability. Discover the difference with BONOSS—built for drivers who demand excellence.
