Properly using 4 lug wheel spacers is legal in most countries and regions. As long as you don’t push the wheels and tires too much out beyond the vehicle’s fender flares, it is OK to use wheel spacers. The key is to stick to reputable brands that are hub-centric and match specific vehicle bolt patterns precisely. The legal and safe 4 lug spacers should be:
- Quality materials: Forged aluminum wheel spacers can handle the stresses of driving.
- Hub-centric design: Hub-centric wheel spacers reduce the chance of vibration.
- Appropriate size: Proper-size wheel spacers avoid rubbing issues.
- Proper fit: The 4 lug wheel spacers must match your car’s and wheel’s bolt patterns.
- Correct torque: Torquing them to the specified values ensures proper wheel alignment.

4 Lug Wheel Spacers Pros and Cons
Wider Stance:
Many car enthusiasts prefer the aggressive look of wider wheels. The 4 lug spacers can give vehicles a more muscular appearance. A wider, more aggressive stance enhances the wheel style.
Flexible Fitment:
The 4 lug wheel spacers allow you to change wheel offset. Wheel spacers expand your choices of aftermarket wheels. For example, a 15mm wheel spacer allows you to reduce 15mm wheel offset.
More Clearance:
Since wheel spacers are installed between the vehicle hub and wheels, they create more wheel clearance. The extra clearance allows you to install wider tires and larger performance brake calipers that could not fit before.
Enhanced Handling:
By moving the wheels and tires outwards, wheel spacers increase the track width. The wheels are set apart more, providing better traction and improving your car’s grip on the pavement. With these 4 lug wheel spacers, you will experience better control, especially when cornering.

Why BONOSS 4 Lug Wheel Spacers Stand Out?
With over 17 years of manufacturing experience, 1800+ drawing updates, BONOSS provides the best 4 lug wheel spacers. There are several key advantages that make BONOSS forged active cooling wheel spacers a top choice.
1. Verified Active Cooling Advantages
These BONOSS forged active cooling 4 lug wheel spacers are designed with petal-shaped grooves. The grooves allow the external cold air to flow continuously inside the spacer when it rotates. The air takes away the heat, actively dissipating heat for the braking system. If you intend to install performance brakes, BONOSS wheel spacers will give you a much better experience.
2. Top-quality Aluminum Alloy
Considering the strength and rustproof needs, billet aluminum is more suitable for daily driving or off-roading use. BONOSS forged active cooling 4 lug wheel spacers are made of forged 6061-T6 or 7075-T6 aluminum alloy. The tensile strength is up to 572 MPa (AL7075-T6). Such wheel spacers are strong enough to undertake hard driving.
3. Advanced Hub-centric Design
BONOSS forged active cooling 4 lug wheel spacers come with better multi-stage hub-centric lips. The hub-centric metal ring is machined to be multi-layers, and the bevels fit the corresponding hub flange, which means zero wheel vibration. This effectively guarantees safety, stability, and reliability in driving.
Frequently Asked FAQs
Q: Are wheel spacers good or bad 4×4?
