In the automotive market, there is a range of potential good 4WD wheel spacers sizes, including 3mm, 5mm, 10mm, 12mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, and 50mm. Selecting the right size is a personal decision based on your vehicle specifications – wheel gap, PCD, CB, and wheel offset.
Choosing the right one depends on your specific model and goals. If you plan to upgrade to larger wheels or a different offset, proper spacers can help with clearance, ensuring your new wheels fit without rubbing against the suspension or wheel well.

Common Sizes for Good 4WD Wheel Spacers
When it comes to good 4WD wheel spacers, thickness sizes generally range from 3mm to 50mm. We believe certain sizes are more suitable for specific models and needs. Here is a breakdown of the most common sizes and what each offers:
- 3-10mm Spacers:
3mm to 10mm 4WD wheel spacers are good for those who need a few wheel clearance to fit bigger brake calipers without drastically changing the overall stance. - 12-20mm Spacers:
A middle-ground option, 12mm to 20mm spacers are good to provide a better wheel stance. These spacers start to deliver noticeable stance changes and improved stability. - 25-35mm Spacers:
Many people will use 25mm to 35mm wheel spacers to achieve an aggressive wide stance. They are typically popular among enthusiasts looking for that bold, flush look. - 40-50mm Spacers
Good 40mm to 50mm wheel spacers are ideal for serious off-roaders who need the extra clearance and improved track width. They’re best suited for pickup trucks with larger wheels or upgraded suspensions.

Who Sells the Best 4WD Wheel Spacers?
Always stick with established brands known for quality and reliability. Companies that provide quality well-made wheel spacers invested a hefty sum in designing and testing their products. With over 17 years of manufacturing experience, 1800+ drawing updates, BONOSS provides the best 4WD wheel spacers for off-roading adventures.
1. Verified Active Cooling Benefits
For example, BONOSS forged active cooling 4WD wheel spacers come with heat dissipation grooves to improve brake cooling efficiency. The heat dissipation grooves are craved behind the spacers. When rotating, those grooves allow the external cold air to flow continuously inside the wheel spacer. The air takes away the heat to actively dissipate heat for the braking system.
2. Optimized Hub-centric Design
What’s better, BONOSS forged active cooling off-roading wheel spacers come with multi-stage hub-centric rings. The hub-centric metal ring is machined to multi-layers, and the bevels fit for the corresponding hub flange, which eliminates any possible gaps. This reduces the chances of vibrations.
3. Useful Disassembly Grooves
One standout feature of BONOSS forged active cooling 4WD wheel spacers is the unique disassembly grooves. Place a screwdriver into the notch and you can simply apply force at an angle to separate the spacer from the brake rotor. This makes the spacer easier to remove and extends its overall service life.
