- For years now people have wanted to add offroad capability to their Sprinters. Most folks in the offroad world know one of the best ways to accomplish this is through gearing and a locking differential. For those new to locking differentials check out all the upgraded features of the Owl Axle

Very excited to see that you literally opened up your headquarters right down the road from me off power rd.. I will be stopping by the say hi soon
That’s awesome and I really want one. However, it’s twice as much as I was expecting. I’ll be putting this off for a while.
This upgrade is awesome, but has anyone seen a Sprinter with a rear, a central and a front locker? I actually cant understand why mercedes does not offer it as an option like Iveco doeas with the daily 4x4.
I actually think that you can get these from off the shelf components if you have the know how and maybe some fabricating skills
Looks like a great product. Will it be available to order and not just purchased with fitting? Would love to get one over to the UK to fit to my upcoming build. Will be running 285s on 17s on the new AWD, L3 8400lbs base weight and my my only option is an air locker right now, this is far more preferable! We have a number of UK suppliers very used to importing Quality
US Sprinter products.
Have you upgraded wheel bearings and does the axel upgrade impact GVM?
I've spent a ton of money on accessories for my sprinter from almost all the major sellers, looks like $10k is where I draw the line. Looks like its the ARB's for me. Nice product though.
John, can you talk a little about the effect on top speed and MPG?
MPG is different for every setup, but if you are running larger tires, then the proper gearing will improve both MPG and performance. These vans are governed to 80mph so no effect on top speed.
I wonder whether the governing is only on more recent models? I have a 2020 Storyteller and have been over 80 on long flat highways.@@owlvansengineering
@@clayjames2461 With larger tires, the van can travel faster because the van thinks you're going slower due to the slower rotation of the larger tire.
First. Keep it up Owl vans 🦉
Looks like this should have a much higher GAWR than factory. Do you have that figure available?
why no option for the 3500?
Bonjour et pour le crafter?
If the gearing makes it faster off the line, it will also reduce highway mileage. How much?
Have you done any long term testing on the transfer case after re-gearing the rear diff? Even with the locker not engaged, but when in 4wd mode, the planetary gear in the TC would be spinning at a different speed than originally designed for. Are you sure this won’t cause any long term issues? Or do you just not use 4wd that often anymore once you have the locker installed?
Makes perfect sense to worry about. Turns out the Sprinter uniquely has different front and rear gear ratios from the factory. Front is 4.15 rear is 3.93. So different gearing front and rear is not an issue for the Sprinter.
@@owlvansengineering I did some more research on this and you're right, the front diff always has the same ratio (4.2). But turns out Mercedes makes 6(!) different transfer cases, each for a different rear axle ratio. So they match the front/rear by adding some type of reduction gear inside the transfer case. The six transfer cases you can order from Mercedes (maybe not in the US, but in Germany for sure) are for the following axle ratios: 3.69 (48:13), 3.923 (51:13), 4.18 (46:11), 4.36 (48:11), 4.73 (52:11) and 5.10 (51:10).
With the transfer case being an "open style" differential, of course you're going to be able to run mismatched front/rear axle ratios (that's the whole point of a differential), but the gears inside the transfer case are going to be spinning constantly when engaged in 4WD.
I know Agile Offroad also does this with their ARB locker, and apparently it doesn't cause any issues. But I'd be curious to hear a long-term review of someone who has changed their rear axle ratio, NOT changed their transfer case accordingly, and also runs 4WD for extended periods of time (for example someone that lives in a harsh snowy environment, requiring 4WD to be on all the time). If 4WD is only used for short sections on technical trails here and there, I can see how there's "no problem" in running a different rear axle ratio without the appropriate transfer case.
The part number for the 3.92 transfer case is 9072800500, whilst the part number for the 4.18 transfer case is 9072800600. I'm sure if it was truly "ok" to run a different rear axle ratio, Mercedes wouldn't have made these different transfer cases.
Curious to hear what you think!!
Does this work with sprinter 3500 awd? Might be a chance to get rid of dual rear wheels and convert into super singles. I would be very much interested if it works on 3500 awd
Proby not. I have a 3500 Super Single, and Owl advised it will not work. The frame is going to be different from 2500 to 3500, and thee are essentially build for the 2500s that everyone seems to buy. The SuSi is not available in 4x4, so 2500 is the popular choice.
Can Sprinters be outfitted with portal axles to enhance ground clearance?
Yes, but currently nobody makes them. They would be very expensive. I’m sure as this segment continues to grow someone will start making them
Will the axle be available in Europe as well.
That's, what I'm looking for ...
We can ship to Europe. You would need to get a freight forwarder and we can ship it to them. Email support@owlvans.com

How can you change the rear gearing without changing the front gearing?
Sprinters are odd and already have different gearing in the front and rear. I know it doesn’t make sense but they have something in the transfer case that allows this
To much talk 😮
Are people blowing out their rear axle assemblies on Sprinters?
Some people are but mainly this upgrade is for the locker, gearing and much more robust axle shafts
