Since the picture above I have installed a Timbrens Severe Duty SES. These are semi-truck sized bump stops that replace the stock bump stops. They are actually in contact with the axle when loaded and do support part of the weight you are hauling in the truck. They do help decrease squat and sway somewhat, even when added on top of the benefit provided by the Stableloads. The jury is still out on the Timbrens though.
I was able to install a Hellwig Big Wig rear Anti-sway bar yesterday. Installation can be a challenge if you are doing it alone. It was difficult holding both ends of a heavy sway bar at the right height, keeping it level, and lining it all up to be able to also insert the bolts in the mounting brackets and get the threads started at the same time. But I managed. I noticed a definite improvement in sway before I had even left my driveway. Cornering is much more stable and predictable feeling. It actually feels normal taking a turn at the posted speed limit or a little above, which was never the case before. I would say that the Hellwig rear anti-sway bar decreases sway by 2/3 compared to before. A pickup with a heavy and
tall load is going to sway some when crossing a gutter at an angle at slow speeds. Before the truck would sway back and forth 6 or 7 times. Now, it sways back and forth 2 or 3 times, which is much more live able. As far as improving sway, an anti-sway bar has made a lot more difference than either the Stableloads or the Timbrens. I think it should be the first improvement made to a truck that is hauling this heavy and
tall of a load.
I did a lot of research into the two available anti-sway bar options, Roadmaster and Hellwig. The Hellwig sway bar is 1 5/16" in diameter, and it mounts behind the axle with the ends of the sway bar pointing to the back of the truck. The Roadmaster sway bar is 1 1/2" in diameter, and it mounts under the axle with the ends of the sway bar pointing to the front of the truck. After reading the installation instructions for both, and installing the Hellwig anti-sway bar, I noticed that the two sway bars would not interfere with each other at all. If someone wanted the ultimate anti-sway set-up it would certainly be possible to use both sway bars at the same time.
I also took a trip to a CAT scale yesterday.
The sticker on my truck's door says:
Front axle capacity 6,000 lbs. My loaded front axle weight is 5,140 lbs
Rear axle capacity 9,750 lbs. My loaded rear axle weight is 8,040 lbs
The trucks fuel tank and DEF tank were full. The Arctic Fox 992 had everything in it to go camping except the food that goes in the fridge and our clothing. The holding tanks on the camper were empty. (46 gallon freshwater tank)
It looks like I am well within the axle weight limits of my truck.
