Sway Bars on AI

Has anyone installed anti-sway bars on the Sprinter with improved handling. Other RV forums for Sprinter chassis have noted improved handling but I trust this forum. I searched but found no threads?

Itís in here (this forum) somewhere. Yes, we upgraded the sway bar on our T1N and it made a huge improvement. I donít know what the verdict is for the NCV3.

The suspension system works together, various pieces. At the same time as we put the sway bar, we upgraded to Koni shocks on the rear. They also helped.

Prior to our current trip, we put Koni struts on the front. I am not happy with them, but I donít know if my expectations are realistic as to what is achievable.

MillionMileSprinter recommends Fox shocks, hands down. Iíve seen them recommended elsewhere but they are $$$$$ and I wasnít about to consider them until / unless I received first-hand testimony from someone I trusted because, ya know, ya canít trust everything you read on the internet. So the Fox option is now something that I will research further.

Your Sprinter already has anti-sway bars. Some people think it helps to change to heavier bars, but there are trade-offs since they don't dampen side to side rocking. Heavier bars might even make it worse. I followed many comments on the Sprinter-Source forum and concluded that switching to max dampening Fox shocks would be best. I've been happy with results.

Thank you, my search for Fox shocks shows no availability. I will look at the other forum.

Contact John Brindell at Agile Off road in Southern California. He is setting up Fox Shocks for Sprinter 3500 duallies. I bought mine from him. Great response. Just ask for a quote and tell him some basic details of your Interstate-Sprinter.

I had a Roadmaster Antisway bar installed to help with crosswind issues in our non-ext AI. Any crosswinds over 30mph would cause an error and I'd lose cruise control as well as the stability system ESP. I'd have to stop and turn off the motor and then it would work again. The new anti swaybar along with other suspension mods eliminated this issue. However, it does nothing for the harsh rear ride (in the non-airbag rigs) so if you have no crosswind issues I wouldn't bother with it.

My experience was not with an Interstate but since you did not get many replies I thought I would share my experience with a class C RV on the sprinter chassis. I replaced the stock rear sway bar with a Hellwig brand and it improved the handling significantly including in crosswind situations. I currently own a 2018 Interstate with rear air suspension. It handles better than my previous RV even with the Hellwig upgrade so I am not in the market for any upgrades at this time.

AI927 - thanks for the input. You have confirmed once more that the VB Airsuspension is the best solution for taming the ride on a Sprinter.

I never drove an Interstate without the rear air suspension so I cannot comment on the difference between the two. Not to mislead my rv can still have issues with crosswind but it is much better than my class C.

A bigger sway bar helps controll body roll during cross winds quite a bit. But nothing is free and when going over pot holes or when driving on uneven dirt roads, the osolations will be amplified. In some cases violently so. It’s not the end of the world, you just slow down and let the shocks disipate the energy. For most of us, we spend thousands of miles on highways in crosswind conditions and only a few miles on unpaved roads making the risk trade a no brainer.

I have never driven a T1N. But I have driven my friend's 2500 high roof NCV3 w/no VB Air. My AI has VB Air and is the only 3500 I have driven. I live in a region where high winds and crosswinds are just part of daily driving. 30mph crosswinds does not even scare us much anymore after living here almost 20yrs. But comparing my friend's 2500 high roof w/ no VB Air vs. my longer 3500 EXT with VB Air is night/day difference. I definitely feel better crosswind stability with VB Air. My friend's shorter 2500 does not handle/feel as confident. In my 6,000 miles & 6 months driving my AI mostly on interstates, I have never once experienced the type of feeling others describe when big rigs pass me, when I pass big rigs, or when big rigs cross paths with me from the opposite direction on 2-lane highways. According to everything I have read about the 3500 EXT, the VB Air is almost mandatory if one wants to carry rear passengers. And crosswind stability is touted as one of the side-benefits. I have never ridden in the rear seats of a 3500 EXT. But if the ride as judged from the driver's perspective of a 3500 EXT w/ VB Air is the point of comparison, I would not even want to consider/imagine how harsh the rear ride would be in a non-VB equipped unit. Though my fam says the rear ride is not bad, they also say it is still a truck ride, not our Town & Country minivan ride and definitely not our Mercedes sedan ride. The closest ride to our other vehicles is that of my Ford F150 Harley Davidson Edition, a pickup truck that's literally not made to haul anything, factory lowered and stiffened suspension even worse than standard F150. Making my AI ride any stiffer/harsher than it's current setup is just not acceptable. But if yours does not have VB Air, you may not have a better option than getting bigger sway bars.
