2. What are the benefits of installing BONOSS wheel spacers on Ford Bronco?

Wheel spacers are made to create the desired space between the vehicle hub and wheels. Your Bronco becomes more stable as the wheel spacers provide additional width for the wheel track. With the improvement of the traction, the resistance to rollover as well as the comfort level of handling the vehicle improves a lot. The appearance gets a boost with the wheels flush with the fender line. They are also an instant and cost-effective solution to add custom wheels or big brake kits to your Ford Bronco. In addition, BONOSS Bronco wheel spacers apply the Global Pioneer Active Cooling Technique which utilizes the rotation of the spacers to allow the external cold air to enter and continuously flowing inside the spacers, enhancing the heat dissipation of the braking system. The braking efficiency gets improvement, driving is safer.

4. How does the active cooling function works on my Ford Bronco?

As a professional Ford Bronco wheel spacers designer and manufacturer, BONOSS created the Global Pioneer Active Cooling Technique, breaking the single functionality of the traditional wheel spacers. The special petal shape grooves utilize the rotation of the spacers to allow the external cold air to enter and continuously flowing inside the spacers, enhancing the heat dissipation of the braking system. The symmetrical design allows for multiple grooves to work at the same time, no matter it is on the left or right wheel, whether driving forward or reversing, the purpose of heat dissipation can be normally and effectively achieved. Install BONOSS active cooling wheel spacers helps improve the heat dissipation of the brake system, reducing brake fade while providing the functions of traditional spacers. The cost of manufacturing an active cooling wheel spacer nearly equals the traditional alternatives. You don’t need to pay extra fees for the cost, that is why BONOSS offers better functions and higher performance wheel spacers but maintaining a particularly friendly price.

5. Are wheel spacers safe on Ford Bronco?

Wheel spacers have existed for multiple decades, and there is very little opportunity for wheel spacers failure. They have always been used widely, even within the highest level of racing events. As long as you use high-quality Bronco spacers and install them properly, they are just as safe as normal wheel changing. Just as your wheels, tires, and brake mods, only good products can ensure driving safety. The quality and safety are often depending on the design, materials, performance, and manufacturing process. BONOSS wheel spacers are designed with actual measurement, using forged AL6061-T6 material (tensile strength ≥ 310Mpa), and matching with ISO standard grade 12.9 wheel studs and ISO standard grade 10 lug nuts, and over 66 SGS TÜV test reports certificated. Precision at 0.02mm tolerance, which offers high surface quality, more importantly, safer and more professional.

6. Why you need Bronco hub centric wheel spacers?

Hubcentric spacers offer a better system of support and stability. They are designed to make a snug connection between the wheel and vehicle hub, reducing the high-speed vibration. Based on traditional hubcentric Bronco spacers, BONOSS has optimized this design to further reducing the chance of high-speed vibration, it is called multi-stage hubcentric design. According to the actual test, the effect of BONOSS multi-stage hubcentric wheel spacers is far better than the common alternatives, which fit more perfectly, safer, and more stable.

7. What are Ford Bronco wheel spacers made of?

BONOSS manufactures Bronco wheel spacers with high-grade forged 6061-T6 billet aluminum alloy which features many desirable properties such as high strength, wear-resistance, excellent toughness, impact resistance, and high-temperature resistance. This metal performs good mechanical properties: Tensile strength≥310Mpa, Yield strength≥275Mpa and Failure Elongation≈10%. Compared to universal wheel spacers selling on the market, they have undergone a continuous forging process, the strength and toughness are greatly improved. Precision at 0.02mm tolerance, which offers high surface quality, more importantly, safer and more professional.

8. What’s the performance of the matching studs and nuts of Bronco wheel spacers? What does the BONOSS Engraved mean?

The matching wheel studs of BONOSS Bronco spacers applied high-strength JIS SCM440 steel material. Take the matching wheel studs as an example, they have achieved ISO standard grade 12.9, tensile strength≥1,220Mpa, limited life range test≥2,000,000 stress cycles without damage, ultimate tensile load≥152,000N, hardness (HV)≥395, NSS≥500H… And the matching lug nuts have achieved ISO standard grade 10, proof load≥1110Mpa, hardness (HV)≥349… Many competitors often use other brands of studs and nuts in pursuit of lowering the cost, and these studs and lug nuts are often only marked with metric units without brand engraved. In view of this, each BONOSS wheel stud or lug nut is “BONOSS engraved”, meaning these matching wheel studs and lug nuts are made by BONOSS’s own factory, the quality is guaranteed, customers’ interests are protected, and BONOSS takes the quality responsibility.

In addition to aesthetics, there are practical features. Knurling patterns can 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 spacers. BONOSS aims to provide wheel spacers for Ford Bronco with more additional functions, safer, higher performance, more professional design, and better installing experience. BONOSS independent design department insists on professional manufacturing and continuous optimization of the design.

12. How do Ford Bronco wheel spacers affect handling?

Wheel spacers bring your Bronco rims and tires outwards, increasing the distance between the left wheel and the right wheel. And most track racing cars would make use of every millimeter of the wheel-wells space available in their design for the highest performance and the best exteriors. A wider wheel track means better traction, hence increasing body control experience, offering better corner performance, and more stable driving. With the Bronco spacers, you can fill the gap in your Bronco fenders and get a more aggressive and powerful look. Finishing with 0.02mm tolerance, BONOSS wheel spacers fit more perfectly to the wheel hub, which means reducing high-speed vibration, offering a smoother driving experience.

13. Will wheel adapters allow my Bronco to install OEM wheels of other vehicles?

Wheel adapters (also called rims adapters, lug adapters, or PCD adapters) are designed to change bolt patterns, center bore diameters, and correct wheel offset in order to properly install wheels that are not specifically made for your car. BONOSS offers a huge range of Bronco wheel adapters to fit a massive variety of different vehicles. Common requests from our customers include PCD conversion, CB conversion adapters for other vehicles’ OEM wheels, or aftermarket wheels (e.g., 6×139.7 to 6×132 wheel adapters, 6×139.7 to 8×180 wheel adapters, Bronco 6 lug to 8 lug adapters). Improper wheel changing leads to an increase in driving risk. If you would like to install wheels with different sizes, wheel adapters will be your instant and most cost-effective option. Done correctly, your excellent modification will be advantageous.

14. How thick Bronco wheel spacers do I need?

Here is a simple method: use a straight edge such as a metal ruler, place the straight edge on the outermost part of the rims where the wheel comes closest to the fender (preferably the top), then, measure from the outside wheel to the straight edge. This distance is the size spacer you will need to achieve the look that flushes or nearly flushes with the fender line. Too thin, you will still have wheel/caliper interference. Too thick, and your tires will hit the fenders. Use proper size of spacers not only ensure safety but also avoid breaking your local laws and regulations. Common requirements like 2-inch wheel spacers Bronco, 1-inch wheel spacers Bronco, 1.5-inch wheel spacers Bronco… Currently, BONOSS provides 25mm-50mm thickness spacers to meet your needs.
