Rear sway bar

Have been towing a 24' camper with my diesel GC and a Blue Ox hitch. The short wheelbase (compared to a full size truck) is subject to some instability particularly when big rigs pass at high speed. Not enough to force me into another lane but enough to keep me on edge at all times. An article in this months Trailer Life magazine had a GC towing a similar trailer. The GC had a Hellwig rear sway bar installed and supposedly this improved handling. Has anyone here had experience with this? Cost is under $200 for a self install which is doable. Also--would this affect the factory warranty? By the way--other than the slight sway the GC does fine--handles hills as if they weren't even there. Getting about 16 mpg towing under varied conditions.

Re: Rear sway bar

Anti sway bars act like a spring along with tires and coil spring. If you feel the rear is too soft a sway bar is often the cheapest way to add more spring. Does it have to be Hellwig? I was considering adding the bigger SRT bars.

Re: Rear sway bar

Mowingy,
I installed a Hellwig bar on two other trucks and they worked fine and improved over stock. In regards to warranty, just because you modify your vehicle, the change will not affect the warranty. The Magnuson-Moss act effectively states that making modifications to your vehicle does not affect the warranty. Generally speaking, the dealer must reasonably prove your modification(s) affected a warrantied component to fail in order to deny a warranty claim. Even then, they can't void your whole factory warranty.

I worked for a ECM chip company and anytime a dealer gave one of our customers grief or threatened to void their warranty, we told the customer to mention the M-M act and the noise stopped.

Re: Rear sway bar

Mowingy,

We have Quadralift on our Overland, do you have QuadraLift air suspension on your Jeep?
Also, I use an Andersen WDH which, together with the Jeep sway control, keeps our towing set up extremely steady at all speeds.

Re: Rear sway bar

No quadralift--just ordered the Hellwig sway bar. Going towing in a couple of weeks. Will post results after trip.

Re: Rear sway bar

I just towed my 5,500 lb boat 1300 miles on air lift bags I added to my rear coils and it helped a ton. Really eliminated sag and bounce.

Re: Rear sway bar

I have a 2 wheel drive summit, I installed the SRT sway bars front and rear. It was a dramatic improvement. Very little body roll now

Mowingy... any update on your Hellwig sway bar? I just read the same Trailer Life article and came here to see if anyone had done it. Very curious for some first hand feedback. Thanks

Re: Rear sway bar

captjeff--been on the road now for 3 weeks towing the trailer about 1500 mi. No appreciable improvement with passing truck/buss blowby. Handles a bit better through turns on twisty roads. All in all there is no substitution for a longer wheelbase tow vehicle.

mowingy... thanks for the reply. I agree that there's no substitute for a longer wheelbase. Lucky I don't tow often.

You mentioned better handling on twisties... I assume that you're talking specifically about towing. How is the day to day ride change without towning anything? Thanks again, Jeff

Re: Rear sway bar

Jeff-feels a bit more secure in twisty turny roads both with and without the trailer.
