The 6×139 wheel spacers are a good idea for aesthetic purposes and fitment issues. By pushing the wheels out, spacers allow you to install bigger tires and larger brakes with no rubbing issues. When choosing the best size 6-lug wheel spacers, there are several popular sizes to consider: 1/2-inch, 1-inch, 1.25-inch, 1.5-inch, 1.75-inch, and 2-inch spacers.
If you are considering improving wheel style and performance, a set of forged 6×139 wheel spacers is the perfect choice. Aftermarket wheel spacers are a popular upgrade for your car. But what sizes and types of wheel spacers are suitable? For your convenience, we make this spacer buyer’s guide to help you quickly find the best flush spacer fitment sizes.
Best 6×139 Wheel Spacers Size Guide
Generally, most experts recommend staying within the range of 1-inch to 2-inch (25.4mm to 50.8mm) for 6×139 wheel spacers. 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 25mm, then 25mm wheel spacers are legal to use.
- 1/2-Inch: If you need extra wheel clearance to clear larger brake calipers but don’t want to push the wheels out too much. Then the 1/2-inch wheel spacers are the perfect options.
- 1-Inch: If you never use wheel spacers, then 1-inch spacers are a good start. 1-inch wheel spacers start to deliver noticeable stance changes and improved stability.
- 1.25-Inch: The 1.25-inch wheel spacers offer a noticeable stance difference and help in accommodating wider tires.
- 1.5-Inch: The 1.5-inch spacers will make your car stance look more powerful, which also improves the stability on uneven surfaces.
- 2-Inch: The 2-inch wheel spacers make your vehicle look even more aggressive and rugged. They also enhance the grip and control when navigating challenging terrain.
Correct Offset:
Wheel spacers reduce the offset. For example, if the stock wheel offset is +60mm, then a 30mm spacer will make the final offset +30mm. The wheels and tires will sit out 30mm from the hub assembly, providing a wider wheel stance.
Who Makes the 6×139 Wheel Spacers?
High-end wheel spacers are produced with top-quality materials to provide optimum performance to the vehicle. For example, BONOSS forged active cooling wheel spacers are made by advanced machinery and undergo a series of safety tests before leaving the factory. BONOSS offers several key advantages that make their spacers a top choice.
1. Active Cooling for Safe Upgrades
Based on traditional rim spacers, BONOSS forged active cooling 6×139 wheel spacers come with heat dissipation grooves. These petal-shaped grooves allow the external cold air to flow continuously to actively dissipate heat for the braking system. Besides, the edge notches act as air collectors, which tremendously enlarges the airflow, enhancing the heat dissipation effect and improving road safety.
2. Aerospace Materials for Improved Strength
Unlike those cheap casting spacers, BONOSS forged active cooling 6×139 wheel spacers are exceptionally strong, making them very durable. Due to the super forging process, BONOSS forged 7075-T6 aluminum spacers feature an ultimate tensile strength of 74000-78000 psi (510-572 MPa). They won’t break easily in off-roading adventures.
3. Precisely Machined for No Deviation
BONOSS forged active cooling 6×139 wheel spacers are CNC machined, precision at 0.02mm, which makes the hub-centric lip more accurate, perfectly fits the wheel hub, and provides a snug connection between the wheel and vehicle hub, reducing the chances of vibrations.
Final Verdict: Elevate Your Car with BONOSS
With these outstanding advantages, it’s clear that BONOSS forged active cooling 6×139 wheel spacers are the best option. Whether you’re upgrading the aesthetics or improving the ride quality, choosing BONOSS ensures that you’re getting a product that meets the highest standards of performance and quality. Your car deserves the best.
