Project Description

Late last week, this Mercedes-Benz G500 installed BONOSS Forged Active Cooling Wheel Spacers, front 26mm(1inch), rear 30mm(1.2inch). They are designed specifically to fit this vehicle and enhance the handling performance as well as an outstanding look. It is a perfect match for the factory forged wheels, due to the precise data. And the hub centric design makes a snug connection between wheel and axle hub, ensuring no vibrations through the wheels. Click the video on the left, let Grace explains detailed info for you!

The Mercedes-Benz G500 is a great luxury large SUV. It’s one of the best off-road vehicles you can ever found, and it is a mix of tough, adventuring spirit with luxury and top-class experience. Its muscular power system, smooth-shifting transmission, and a plentiful list of functions furthermore boost this vehicle’s charm. It is equipped with a 4.0-liter twin-turbo V8 engine. Power and torque reach to 310kW and 610Nm. Easily deal with various off-road situations.


What do wheel spacers do for the G500?

Off-road, though, is where the G500 sparkles. Installing a set of wheel spacers can not only increase offset, enhance the ability to turn, offering a smoother handing experience but also provides a more manly appearance. For changing to a larger brake caliper reason, wheel spacers create an extra clearance between the wheel and hub, ensuring a proper fastening.

Why use hub centric wheel spacers?

One of the reasons for wheel vibration is that the wheels are not actually central to the vehicle hub.  And vibration greatly affects the driving experience, which is not safe. Hub centric wheel spacers are designed to make a snug connection between wheel and axle hub, ensuring the hub carries the weight of the car instead of the studs or bolts. This allows the wheels are truly central to the vehicle hub, meaning no high-speed vibrations through the wheels. Meanwhile, hub centric wheel spacers also reduce the stress on the wheel studs or bolts, improving service life range.


BONOSS Forged Grade 12.9 Extended Wheel Bolts

High-quality bolts for a high-end vehicle. BONOSS Forged Grade 12.9 Extended Wheel Bolts applies SCM440 high strength steel material, which provides extremely high performance.

TUV and SGS actual test report performance parameters are as follows:
Tensile Strength ≥ 1220MPa
Ultimate Tensile Load ≥ 152000N
Proof Load ≥ 121000N
Limited Life Range Test ≥ 2000000 Stress Cycles Without Damage
Neutral Salt Spray Test ≥ 192H


Step 1
Mount the wheel spacer and thread the lug bolts in. For precise design, it can be installed smoothly.


Step 2
Use a torque wrench with a 17mm hex socket to fasten the bolts. The torque should be 140 N.m.


Step 3
Mount the wheel back. Hold the wheel firmly and be careful of a sudden drop.


Step 4
Land the vehicle, use the torque wrench and 17mm socket for the second fasten. The torque should be 140 N.m.

Addtional Information:

  • BONOSS wheel spacer thickness can be customized flexibly, which is compatible with most vehicles. Thus, if you would like different sizes of wheel spacers, feel free to contact us. This Mercedes-Benz G500 uses front 26mm(1″), rear 30mm(1.2″), PCD 5×130, CB 84.1.
  • The extended bolts are spacer structure design, which effectively eliminates the bolts loosening and abnormal sound caused by the PCD hole coaxially deviation between hub and shaft head. This Mercedes-Benz G500 uses ball seat bolts. If you would like a set of extended bolts, please ensure the seat type of the bolts is suitable for threading tightly. And, if you don’t know the proper length, you are welcomed to contact our tech staff freely.
  • Each BONOSS product is printed with the logo of “BONOSS”. This offers an easy method to distinguish other fake and inferior products. At the same time, it also provides a way to find our after-sales service. Our products are 10 Years Limited Warranty (new products with 12 months warranty), which is an excellent and cost-effective choice for your car upgrades.
