Installing 5×108 wheel spacers is one of the easiest and simplest ways to boost your car’s handling. By moving the wheels and tires outwards, they provide better traction, handling, and stability. The wheels are set apart more, providing better traction and improving your car’s grip on the pavement.
With these 5×108 wheel spacers, you will experience better control especially when cornering. Since the wheel spacers push the wheels and tires out a few distances, they essentially subtract the offset. So, car spacers provide a similar effect as lower-offset rims. But the big question is: what are the best 5×108 wheel spacers? Let’s dive in to help you make a wise decision.

Choosing the Right 5×108 Wheel Spacers
Safe Sizes:
To avoid rubbing issues, it is recommended to keep the tires stay within the body width. This safe size requires some basic measurement. If the wheel gap is about 12mm, then 12mm wheel spacers are legal to use.
- 3mm to 10mm:
For those who like to keep the OEM similar wheel styles, 3mm to 10mm wheel spacers are a good idea. They provide just enough space to clear bigger brake calipers. - 12mm to 20mm:
Installing 12mm to 20mm spacers are typically popular among many people looking for a better wheel stance. They provide more stability while cornering. - 25mm and above:
These 25mm and above wheel spacers are more suitable 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.
Correct Offset:
Wheel spacers reduce the offset. For example, if the stock wheel offset is +50mm, then a 15mm spacer will make the final offset +35mm. The wheels and tires will sit out 15mm from the hub assembly, providing a wider wheel stance.
Bolt Pattern (PCD):
Only the bolt patterns that match can you achieve a proper wheel fitment. Therefore, it’s crucial to find the right dimensions for your car before shopping for a new set of wheel spacers.

Who Makes the Best 5×108 Wheel Spacers?
When selecting the best wheel spacers for 5×108, 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 5×108 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 wheel spacers improve the cooling efficiency to reduce brake thermal decay.
2. Aerospace-grade Aluminum Materials
All BONOSS forged active cooling hub-centric 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 (AL7075-T6). High tensile strength gives it strong resistance to being pulled apart, making it resistant to bending and breaking.
3. Strong Fasteners for Zero Loosen
To safely secure the spacers, BONOSS provides ISO grade 12.9 wheel studs (tensile strength≥1,220 MPa) and ISO grade 10 wheel nuts (proof load≥1,110 MPa). They are meticulously coated with Dacromet. This type of coating gives neutral salt spray resistances exceeding 500 hours. They won’t loosen easily in off-roading conditions.
Frequently Asked FAQ
Q: Are 5×108 wheel spacers safe for 4×4?
A: Yes, the 5×108 wheel spacers are safe for 4×4 adventures. Done properly, it is exactly safe and beneficial to run wheel spacers.
Q: Do I need an alignment after wheel spacers?
A: Adding 5×108 wheel spacers won’t mess up alignment as all the suspension components will still retain their basic geometric relationships with each other. So, you don’t need an alignment if you just install spacers.
Q: Do I need wheel spacers on all 4 tires?
A: Since the 5×108 wheel spacers will move your wheels outwards from the corresponding vehicle hubs. If you want to keep the wheels following the same track, it will be better to add wheel spacers on all 4 tires.
Final Verdict: Upgrade Your Car with BONOSS
From innovative active cooling benefits to certified materials and precise manufacturing, BONOSS forged active cooling 5×108 wheel spacers are engineered to enhance your driving experience with safety, strength, and reliability.
