Installing Bronco wheel spacers is a popular modification for many off-roaders. This is obviously a good idea that we’ll cover in detail in the fitment guide. But first, let’s check out the basic data about one of the most adventurous vehicles on and off the road.
What Size Bronco Wheel Spacers Do I Need?
1966-2027 Ford Bronco Wheel Size Table
| Model | Bolt Pattern | Center Bore | Thread Pitch | Reference Spacer Sizes | Torque Spec | Seat Type | Socket Size |
|---|---|---|---|---|---|---|---|
| 2021-2027 Bronco VI (U725) | 6×139.7mm | 93.1mm | M12x1.5mm | 1 inch to 1.5 inches | 99.5 ft-lb (135 Nm) | Conical seat | 21mm (13/16”) |
| 2022-2027 Bronco Raptor | 6×139.7mm | 87.1mm | M14x1.5mm | 1.25 inch to 1.5 inches | 150 ft-lb (204 Nm) | Conical seat | 21mm (13/16”) |
| 1966-1996 Bronco I-V | 5×139.7mm | 87.1mm | 1/2″-20 UNF | 1 inch to 1.75 inches | 99.5 ft-lb (135 Nm) | Conical seat | 21mm (13/16”) |
We cover the old model data to help you pick early Bronco wheel spacers. Although we have listed recommended sizes in the table, the perfect wheel spacer sizes rely on a serious measurement.
1. Check Bolt Pattern & Center Bore
The bolt pattern (PCD) and center bore (CB) are important factors in identifying whether the wheel spacer matches. Unlike other measurements, it is hard for you to measure these two factors without a set of professional instruments.
Even minute errors can lead to wrong installation and serious safety risks. That is why we set up this Bronco spacer size table to help you find out the correct data quickly. For example, the bolt pattern of the 2026 Ford Bronco is 6×139.7mm, and the center bore is 93.1mm.
2. Stud Length Measurement
The vehicle wheel stud length is a key factor to ensure the wheel fits snugly with the spacers with no gap. It is necessary to determine whether you need to cut the factory wheel studs to fit the Bronco wheel spacers:
- Measure the protruding length of the car wheel studs,
- Check the depth and position of the wheel pockets.
If the wheel pocket depth + spacer thickness ≥ protruding stud length, then these Bronco spacers will fit properly without cutting the factory wheel studs.
3. Fender Gap Measurement
It is the key point to figure out what sizes of wheel spacers give your Ford Bronco a perfect flush wheel stance. Take a straight edge and place it against the outermost part of the rims/tires, then measure from the outside wheel to the fender line. Repeat this on the front and rear wheels, and you’ll soon get the perfect thickness.

Driving Experience of Bronco with Wheel Spacers
How does it feel after installing Bronco spacers? Whether you opt for better handling in daily driving or seek enhanced stability in off-roading adventures, the Bronco with wheel spacers meets the requirement.
One of our customers, John Noel own a 2026 Ford Bronco (four-cylinder and four doors), and he has achieved 0-60 mph acceleration of around 8.4 seconds. Adding wheel spacers for 2026 Ford Bronco won’t obviously affect the acceleration.
Another customer, Charles Daley, installed Bronco 1.25” wheel spacers. Thanks to the increased track width, the Bronco relays confidence and stability to its driver in off-road driving. “Really changes the look! Ride is much better as well,” – by Charles Daley.
What most people care about is the fuel economy. The Broncos (non-Raptors) are rated between 17 mpg and 20 mpg in the EPA’s database. We ask our customer, Peter River, for the MPG after using the 2022 Ford Bronco wheel spacers. “I understand manufacturers keep the wheels tucked in tight for MPGs, but they look so much better when they’re more flush with the body. I have owned a turbocharged V6-powered 2022 Bronco Badlands and installed 1.5” spacers for several years, and it averaged 17.4 mpg over the course of 40,000-plus miles.”
How to Install Bronco Wheel Spacers?
To ensure safety, remember to park the vehicle on level ground. Turn off the engine and press the electronic parking brake (EPB). Make sure that the surrounding environment of the vehicle is safe and free from interference;
First of all, loosen all the lug nuts of one wheel, but do not completely remove them. Then lift the car, and use the correct jack stands to support it. It is recommended to work on only one wheel at a time.
Step 1: Remove the Wheels
Now, you can completely remove the lug nuts. After removing all the lug nuts, take the wheel off the vehicle and carefully set it aside.
Step 2: Clean the Wheel Hub
Spray degreaser and use the wire brush to remove corrosion and dirt from the wheel hub. Wipe down the entire surface to ensure it is smooth.
Step 3: Install Bronco Wheel Spacers
Firstly, remove the provided wheel nuts from the spacer studs. Then, slide the wheel spacers onto the vehicle’s studs and hub, and make sure that the spacer firmly seats and flushes against the wheel hub.
Secondly, use the provided wheel nuts to fasten the spacer. Then tighten them to specific specifications in a star pattern using a torque wrench. The spacer lug nuts should be torqued to the manufacturer’s torque specification – typically 83.3 ft-lb (113 Nm). Check REFERENCE torque spec for Bronco wheel spacers.
Step 4: Reinstall the Wheel
Carefully slide the wheel onto the spacer’s studs and tighten your factory lug nuts in a star pattern. Make sure there is no gap between the spacer surface and the back of the wheel or between the vehicle hub and the back of the spacer.
Step 5: Torque the Wheel Nuts
Carefully lower your vehicle back to the ground. Use a torque wrench to tighten the lug nuts in a star pattern. The factory wheel nuts should also be torqued to the vehicle manufacturer’s torque specification. Check the torque spec for a Ford Bronco.
Special Note:
If you install Ford Bronco wheel spacers, we recommend the same 83.3 ft-lb (113 Nm) to secure the stock M12x1.5 wheel nuts. Check the pro tips for Bronco spacer torque installation.
Step 6: Post-Install Bronco Spacers
Repeat these steps for all of the other wheels. After installing wheel spacers on the Ford Bronco, take your vehicle for a quick test drive to check if there is any abnormal noise or vibration. If there are no problems, you are ready to enjoy the new wheel spacers.
It is crucial to re-torque your new wheel spacers after the first 50 to 100 driving miles. You may need to remove the wheels to tighten lug nuts that secure the spacer onto the vehicle hub. Then, just re-torque them every routine tire maintenance.
Frequently Asked Questions
Q: What size wheel spacers are best for a Ford Bronco?
A: For most stock Broncos, 1-inch to 1.5-inch is the best wheel spacer size. If you like a perfect flush wheel stance, figuring out how much the fender gap helps you choose the correct ones. For example, if the wheel gap is 1.25 inches, then 1.25-inch spacers should make your wheels flush with the fender flares.
Q: Do I need hub-centric or lug-centric spacers for my Bronco?
A: We recommend using hub-centric spacers instead of lug-centric ones. Hub-centric Bronco spacers are centered by the axle hub, and the lugs can hold the wheels stably and firmly. This is a hub-centric connection, which keeps your vehicle from experiencing unnecessary vibration.
Q: What’s Bronco wheel spacer torque specs?
A: The REFERENCE torque on the Bronco wheel spacer is 83.3 ft-lb or 113 Nm. Over-tightening wheel nuts causes stress fractures, which make the nuts stretch the stud, leading to failure around the rotor. Under-tightening the wheel nuts, the clamping force will not be enough to secure the wheels.
Q: Do I need an alignment after Ford Bronco wheel spacers?
A: You don’t need an alignment if you just install Bronco wheel spacers. As long as you install them properly, quality wheel spacers don’t affect the alignment at all. Once it comes to changing the wheels and tires, we recommend an alignment after the installation.
Q: Are Bronco 2” wheel spacers safe?
A: Yes, using 2-inch wheel spacers is safe for a Bronco. To ensure safety, make sure you get high-quality forged wheel spacers and install them correctly. Apply proper torque to tighten each wheel nut and check the tightness in every routine maintenance to prevent potential risks.
Q: How often do you check wheel spacers for Ford Bronco?
A: Regular inspections avoid most issues. It is always a good idea to give your Ford Bronco wheel spacers a check and retorque them about 5000 miles of driving. Immediately check them after heavy off-roading. Like any other suspension parts, the Bronco spacers need regular inspection to function safely.
Q: What are Ford Bronco bolt pattern/ center bore?
A: The bolt pattern and center bore of a Ford Bronco are 6×139.7mm/ 93.1mm for 2021-2027 models and 5×139.7mm/ 87.1mm for early 1966-1996 models. Vehicle-specific wheel spacers should come with the same bolt pattern and center bore to achieve a proper fit. This prevents dangerous vibration at highway speeds.
Q: Are Ford Bronco wheel spacers legal?
A: The Bronco spacers are legal in most countries and regions. By far, no existing federal law says wheel spacers and adapters are illegal. The key to keeping spacers legal is not to overdo it. Stay within your state’s guidelines, and you’ll be driving legally with wheel spacers.
Buying Tips for Ford Bronco Wheel Spacers in 2026
1. The Flush Look:
The main reason to use Bronco wheel spacers is to fix the tucked-in look of OEM wheels. Proper wheel spacers push the wheel out to align perfectly with the fender. This creates a more aggressive and powerful stance. If you never use wheel spacers, starting from 1.25-inch may be a good idea.
