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!

I do not recommend using spacers on a G as they increase the cantilevered load on the bearings which can lead to premature wear and failure. Ask me how I know.

Numerous posts on this forum ask how big can my tires and wheels be without rubbing or requiring a lift. No one seems concerned with any consequences beyond appearance. Mounting wheels further outboard, either with spacers or with wheels having more outward offset, in order to accommodate more tire width, increases axle and bearing loads. Low profile tires with less sidewall cushioning transfer greater shock loads to bearings and suspension components. Even the increase in combined weight of an aftermarket up-sized wheel/tire setup can become a factor. Well whatever - as long as I look cool.

Yes, the front solid axle G bearings are just barely up to the task. Caveat emptor to those that place a heavier rolling load on them.

Definitely something on my mind when I installed 50mm H&R wheel spacers on mine. I'm very much aware of the extra load on the bearings, and whenever I service it I'm checking for any bearing issues.
Also, braking is definitely affected with the discs further inboard from the tires (much like the HumVee). But, after 15,000 miles on and off-road driving - far so good, no issues. I definitely don't have low profile tires though, so that may help.
I'll report back if/when something finally gives...

The minimal change in load isn't going to make your G fall apart. I've run 35" tires with more outward offset wheels (and sometimes spacers) on several different G Wagons for the past 15 years. No issues. Will you eventually cause more wear and tear on things? Yes, but it is truly insignificant. This G55 has 100K miles on it, and has been on 35" tires with aftermarket wheels (-30mm offset over factory) for 95K of those miles. No accelerated wear on bearings, or even steering components. That being said, the OP of this post is obviously trying to advertise for their product on the forum. First or second post, and it is an endorsement of a random company making G Wagon spacers was a dead give away. If I'm going to run spacers on a truck that I drive 100mph I'll stick with a known quality company like H&R.

I used the H&R spacers (which are extremely well made) and the front bearings went went south within 10,000 miles at 60K.

While it can happen at any time, I'd say that's more of a rarity than common. Accelerated wear on components can certainly happen by adding leverage, but these trucks are pretty tough and generally overbuilt. Part of your problem might have been having 50K miles on the truck already, but even then I think that's a pretty rare case (or perhaps something else was an issue that was contributing to their accelerated wear). Some people might not be willing to sacrifice some logevity for looks, but I'll gladly do it.

I agree there's likely enough design margin in the axle and suspension components to prevent everything from disintegrating in 1,000 miles of driving, but if you've made extreme lift and spacer modifications, I'd be have things inspected every year.

Next video in the series will be “How to pump gas”.

I know you're being facetious, but check out the number of Youtube videos on this topic -- and they're serious! There are two states -- Oregon and New Jersey -- and a couple of local municipalities that prohibit self-service filling stations. If you pull into a gas station in one of these places and make the mistake of initiating self-service, you're likely to get pushed to the ground by an angry attendant. Finding people in one of these places who have never pumped gas in their lifetime is not difficult, and they haven't a clue how to do it.
But perhaps a video "How to use your cupholder" would be instructive.

E552006

HAHA, never knew that!
I couldn’t imagine not being able to pump your own gas.

Yes then, maybe the cup holder video could be less useful!

What's truly offensive at some of these places is the attendant will offer to do your windshield and check your oil -- for a fee.
