While we wait for the updated video of the G550, let’s review the details of the G500 installation. In the Previous Article, we briefly introduced the case of BMW installing BONOSS Lightweight Plus Wheel Spacers, and in this article, we will introduce the thicker spacer installation by Mercedes-Benz models, also a German brand, installing wheel spacers with a thickness of 20mm-30mm. As BONOSS’s hot-selling wheel spacer products, the main product features active heat dissipation, in addition to hub centric remains as BONOSS’s consistent product design standards. In the previous article, we mentioned that thicker wheel spacers will be chosen by more owners with off-road needs, and most of the models installed are mainly suitable for off-road models, such as Land Cruiser, Land Rover, Jeep JL, etc., and of course the G550 we are introducing today, as a Mercedes-Benz off-road model, both Mercedes-Benz’s famous luxury interior and off-road vehicle hard road passing ability.

30mm Wheel Spacers for Mercedes-Benz G550

The question that confused the Mercedes-Benz G550 owner was probably the same as most owners, is it safe to have thick wheel spacers mounted on the wheels? But he finally chose to use Lightweight Plus Wheel Spacers for the front wheels and 30mm Active Cooling Wheel Spacers for the rear wheels. Regarding the suspension system, most off-road vehicles are designed to retain a certain amount of modification space, but this modification space is designed within a reasonable range, as higher chassis off-road vehicles need a wider track to maintain the road. In addition to replacing the wider stock tires, adding wheel spacers to push the tires outward is also a common practice in many off-road races.

We are mainly discussing the bolt fastening wheel hub as an example for European vehicles, what if thicker wheel spacers need to be installed? As we all know, hub centric wheel spacers are used for force transmission through hub centric bolts. Under the condition that the hub centric remains unchanged, can extended bolts achieve stable operation of wheel spacers on the vehicle, it is very worrying, isn’t it? For wheel spacers with a thickness of 20mm or more, BONOSS recommends the use of Active Cooling Wheel Spacers, where the wheel spacers are installed in the hub assembly by means of wheel studs and the hub centric. After the wheel spacers are installed in the hub assembly, the original wheel studs are installed on the wheel spacers in the normal way through the hubs.

What is the difference between Wheel Spacers?

The wheel spacers on the market are mainly divided into Two Types, the first is the hub centric wheel spacers with BONOSS Lightweight Plus Wheel Spacers as an example, which are installed directly through the extended aftermarket wheel bolts, the second is similar to the BONOSS Active Cooling Wheel Spacers’ lug centric wheel spacers, this type of wheel spacers on the market will mount the wheel spacers on the hub assembly through nuts or studs, and then mount the wheel hub on the wheel through the original bolts or extended bolts. The reason for the similarity is that BONOSS also requires studs to mount the wheel spacers on the hub assembly, but this guarantee retains the hub centric design, which means that the hub centric still plays an important role in the pressure transfer path. We have made BONOSS Active Cooling Wheel Spacers a type of hub centric wheel spacers.

What Are Active Cooling Wheel Spacers?

In terms of thickness, most of the wheel spacers above 20mm are designed as Active Cooling Wheel Spacers, and the origin of the name is perhaps better understood from the functional point of view, as the contact surface (back side) between the wheel spacers and the hub assembly is easily found to have petal-shaped air guide slots. These lines are symmetrically distributed and are divided into the air inlet and outlet slots during vehicle driving, thus achieving the role of cooling the brake discs. Among the BONOSS product names, BLA Series wheel spacers are designed for European models with bolts, while BLM Series is designed for Japanese American models with nuts.
