Hellwig 7777 Solid, Heat Treated Chromoly, 1-1/2" Rear Sway Bar

Easy to install. Noticed a better difference in the swaying issue I had with my RV.

Purchased to assist in stopping side to side sway of Class C RV. Sway bar was a much larger diameter bar than stock chassis bar and has helped with the rocking of the RV. Installation, due to its greatly enhanced rigidity, it is somewhat of a challenge to install. With patience, tools, clamps and prybars it is possible for the DIY person to install. Would definitely purchase again.

I have a Class C RV which was built on top of a Mercedes Sprinter 3500 chassis (Winnebago is the RV manufacturer). Driving the RV on the Interstates, with big rigs blowing by and side winds, is unnerving. We heard from our FB group that the manufacturer's shocks were inadequate for the teetering motion. I replaced them and that was a big improvement. But there still was a lot of top-heavy swaying. I replaced the manufacturer's sway bar with this Hellwig sway bar and there was again, dramatic improvement. I believe it rides like a rig should, without constant swaying. My wife could detect the improvement from the passenger side. We now feel the smooth up-and-down motion of the suspension as you normally do on certain roads, but without the side-by-side motion. The ride is closer to a luxury car. I had the sway bar installed, but I have heard from our FB group that you can do it yourself if you are handy doing mechanical work.

This sway bar has made a world of difference in the way our Vita RV handles on the road, especially on turns and curved roads. We can make rough turns without everything bouncing around and worry about things falling out of cabinets. The ride is much smoother all the way around. Installation was easy, simply remove the old sway bar and install new one. Took less than 30 minutes. Highly recommend!!!

I had heard great things about how much the Hellwig anti-sway bar improves performance. They were right. My 2021 Winnebago View stability is soooo much better. I installed them myself, alone in about 30 minutes. I added Sumo SuperSprings up front as well. Great investment.

If you have a motorhome on your chassis, go by the chassis year, and not the year of the coach!

We bought an almost new RV built on a Sprinter 3500XD chassis and it swayed pretty badly when cornering, especially if there was a water trough where we were turning. In addition we also camp on BLM land and since that land is typically not completely level some of the drives to a campsite were white-knuckle drives and my wife asked that I do something to stabilize the RV.We bought the Hellwig sway bar at the recommendation of some of the people on an RV forum that I sometimes browse and it has done a good job in reducing that sway. The RV now tends to sway less and to recover more quickly than before and we are both pleased with how it works.I can not comment on the ease of installation since I had that work done at a suspension shop, but we are satisfied that the purchase was worthwhile.
