The 4WD wheel spacers are installed between the vehicle assembly hubs and the wheels, pushing the wheels outward to give your car a wider stance. There are more benefits that good wheel spacers offer, especially for those who want to make their cars look more attractive and perform better on- and off-road.
Applying proper torque when tightening 4WD wheel spacers is critical to safety. Under-torqued nuts can vibrate loose, while over-tightening can damage components. Check the owner’s manual for any deviations from these specs based on certain wheel styles or conditions. If you are unsure or have any doubts, you can toy with the reference below:
- M12 lug nuts or studs: 83.3 ft-lbs (113 Nm);
- M14 lug nuts or studs: 103.5 ft-lbs (140 Nm);
- 1/2″-20 UNF lug nuts or studs: 83.3 ft-lbs (113 Nm);
- M15 lug nuts or studs: 103.5 ft-lbs (140 Nm);

Good 4WD Wheel Spacers Before and After
Enhanced Handling:
The 4WD wheel spacers increase the car’s track width. With the improvement of the traction, the resistance to rollover is enhanced, and the comfort level of handling the vehicle improves a lot. This is effective when the vehicle is driven in bad weather or when cornering the vehicle.
Improved Griping Ability:
The grip of your vehicle is also strengthened when the wheel track increases. As a result, when the vehicle moves in rough weather or snow even then, it does not lose its grip on the road.
Unique Wheel Style:
Properly install 4WD wheel spacers to fill the wheel arches making your car look sporty, powerful, and muscular. Such a vehicle will surely turn some heads.
Tire Fitment:
The correct sizes of wheel spacers allow you to install wider tires and bigger brake calipers. Adding quarter-inch wheel spacers will prevent your wheels from most potential rubbing issues.

What Are the Best 4WD Wheel Spacers for Sale?
As one of the best alloy wheel spacer manufacturers and suppliers, BONOSS focuses on supplying customers with genuine aluminum alloy wheel spacers. By doing so, BONOSS is able to guarantee quality, safety, and correct fitting. BONOSS offers several key advantages that make their spacers a top choice.
1. Active Cooling for Safe Upgrades
BONOSS forged active cooling 4WD wheel spacers are helpful in improving brake cooling efficiency. The heat dissipation grooves send 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 braking system. This boosts the cooling efficiency, reducing brake thermal decay, and improving road safety.
2. Side Knurling for Enhanced Stability
BONOSS forged active cooling 4WD wheel spacers are finished with a knurling surface on the sides. Knurling can enhance the aesthetics and enlarge the side area so that it can contact more air, boost the heat dissipation effect, and also reduce internal stress. That means improving the performance, strength, and durability of the BONOSS forged 4WD wheel spacers.
3. Hard Anodizing for Improved Durability
Since BONOSS forged active cooling 4WD wheel spacers are made of aluminum alloy, they won’t rust easily. What’s better, BONOSS applies a special hard anodized surface treatment to further resist rust and corrosion. Anodizing creates a perfectly formed to ensure the spacer surface of unparalleled corrosion resistance.
