Would be cool to see AO get a front locker aswell. Iglhaut in germany has one some how through witchcraft. Although only millionaires can afford the $95k price tag
Without going into too much detail, or more is even better..(ie rpm and mpg effects), what are the recommended tire size range for the 3.92, 4.18 and the 4.36 gear ratios you offer.
For most 4wd/AWD applications we recommend the 275/70/17. Max tire size you can go up to is a 285/75/17 but this will require trimming the front and rear fenders. Please keep in mind that we would need to know the van’s year and model to make sure that changing the gear ratio is an option!
Have you put this ARB Air Locker on a Sprinter 3500 Dual Rear Wheels. I am planning on getting my 2011 3500 View Preview smart as dirt to be able to travel Forest Logging Roads with greater clearance for these rougher road.
Hey Paul, sorry for the late response! We have international shipping to Australia. We would love to get this issue squared away and get you that Locker! If you could email info@agileoffroad.com , we will get this resolved! Sorry for an inconvenience!
Will it work with the VB air suspension for the air source or will it need a separate air source? I have a Airstream Interstate 24x which is a Mercedes 3500 chassis.
Any pressurized air source can be used to actuate the locker. Assuming your VB suspension has an air tank, we should be able to use that for the Air locker.
How does a rear locker work with 4ets electronic system and no transfer case locking mechanism? Phisically transfer case’s non locking differential will not transfer power to the back axle when unlocked. This cannot work properly in 4x4 mode in any vehicle on the planet, first because of pure mechanics, second due to All electronics. In Europe Iglhaut tried to „upgrade” the OEM Oberaigner 4x4 system and it works only in 2wd with electronic malfunctions. Multiple customers had damages due to this upgrades. Arb is the Top quality for offroaders but knowing the Sprinter and being able to see the whole production we know there is something missing ;)
It just locks the rears, there's no magic to it. You won't get a locking center diff like a Jeep has, so if your fronts are spinning you're limited to 67% torque to the rears. 4ETS won't even know you're locked -- all it knows is both rears are spinning at the same rate, like they would be if they have traction.
@@bistromat exactly what we said. 4ets will not cooperate with it which means in the end it will have no traction at all. Not only in the back wheels but also on the front wheels. Same goes with Big Tyres and suspension „upgrades”. We have been invited to the facility that created 4x4 system which is installed in Stock Sprinter. We did tests with their technitians and engineers showing how all this „toys” are negatively affecting sprinter vehicles. Oberaigner facility created also a special version with 3 lockers and stronger low gears which was possible to order thru Mb Dealers. Long movie is coming shortly here we have a trailer ruclips.net/video/MSK-czfef7Q/видео.html
In thousands of miles of field testing on the Air Locker we've yet to see any electronic or mechanical issues with the 4ets system in both 2WD & 4x4 mode. In certain conditions we've found (usually with 4ets disabled in 4x4 Low) when a front wheel loses traction the open center differential (transfer case) sends power to the spinning front wheel and not the rear axle. This will be addressed by our 50/50 locking transfer case debuting later in the year.
@@Agileoffroad I understand that you are of bigger knowledge than the 4 wheel drive producers themselves who generally spent years on R&D (they built this systems since 1970's, millions of euros on their facilities in Austria, Germany and Charleston US as well as engineering process. If you change the trasfer case to 50/50 power distribution with OEM parts (as it is in Renault master - the center diff is of the same built as Sprinter) you will get a lot of damages and fractured parts due to not strong enough components which are different for 2wd selectable and permanent 4x4 OEM with 3 lockers. Even the HD permanent Sprinter with 3 lockers has 33/67 power distribution as 50/50 would be too strong for the whole mechanism. As we said we did a full tour at this facilities and interviewed the people who know more about this systems than we ourselves. We talked about all possible mods that are visible on the market (believe me or not they did test US market things) showing how 90% of them have are destructive or bring very dangerous impact on this vehicles and people driving them.
How about you make a carrier for wk2 grand Cherokee. They use Mercedes welded ring gear too and there's no one out there making one. We wanna be able to run lockers dammit lol
Most 4x4 Sprinters don't have matching front and rear gear ratios to begin with. Both of our Sprinters (2019 & 2020) were equipped with 3.92 rear gears. The front differential is 4.20. Somehow (using witchcraft & fairy dust? lol) the transfer case is able to distribute power appropriately despite the difference in gear ratio. After this video was filmed, we changed the rear gear ratio in the 2020 Sprinter to 4.18. After reprogramming the computer with the corrected rear drive ratio we found the transfer case is still able to distribute power as intended. 2WD, 4x4 HIGH & 4x4 LOW function as expected!
@Oberranger We've been running the 4.18 rear gear swap in our van for the past 6000+ miles. No issues so far! 50/50 locking transfer case is being installed next week. No better way to learn how the system works tna good old fashioned R&D.
Looking forward to this for the 3500.
Can't wait! Getting my locker at the end of February! Looking forward to a visit to Santee.
ARB made in Australia. Excellent products.
This will be a game changer for my revel when I go off road.

Good stuff, and most 4 X 4 Sprinters should give this serious consideration.

Will there be a list of dealers or partners for Europe? Are these people getting trained by ARB too?
Greeeeetings ✌🏽
What would you suggest for T1N Sprinter.?
Try and get ARB in Australia to get one installed. It’s been 8 months and still no joy.
Hey Paul, sorry for the late response! We have international shipping to Australia. We would love to get this issue squared away and get you that Locker! If you could email info@agileoffroad.com , we will get this resolved! Sorry for an inconvenience!
Will lockers work on new 2023 sprinter all wheel drive, do I need to change to lockers or just keep all wheel drive?
Question. Will this Locker work on Dully's 3500 or 4500?
Depending on small factors- it should work on the 3500! You can always call and talk with someone who can help further
Will it work with the VB air suspension for the air source or will it need a separate air source? I have a Airstream Interstate 24x which is a Mercedes 3500 chassis.
Any pressurized air source can be used to actuate the locker. Assuming your VB suspension has an air tank, we should be able to use that for the Air locker.
Hi Is there an ARB contact that you have down here in Australia. I have 2020 4x4 Sprinter and would like to have the Air locker installed.
Thanks

What’s the cost of it installed?
About $5,000 if you need an onboard air kit as well!
