2011 Dodge Ram 2500 anti sway bar

The stiffer the truck frame the less need their is for an anti-sway bar. These bars originated with ultra light weight sports cars. A side effect is that when one wheel hits a bump the force is transferred to the opposite wheel. With my truck when there is no load in the bed the bed this is a positive attribute as it softens the ride. Zero difference in handling with the Big Wig when there is a 3400 lb. camper in the bed or I am towing a heavy trailer.

That went away with the 03 updated body. Dodge said the SB wasn't needed because of the increased length and geometry of the new trucks rear springs.

If that is the case then please explain why my '04.5 has one.

Because it's aftermarket.

There wasn't an OEM anti swaybar in 2004.5.

Excellent info - I think I'll put one on for the upcoming season camping.

You won't be disappointed.

I added mine because I was feeling the trailer (1200-1300lbs TW) on slow speed off-camber corners, on winding forest service roads. After the install that feeling went away.

Now I haul 2 quads above the bed rail, with gas/water/wood/etc below the bed rails and still have the same TW. Rock solid on corners and I only use about 20-25psi in the airbags.

Thanks, I've been waffling on this for years and wondering if it would really do any good when towing.

Your 2002 2500 was equipped with the Camper Package. 3500 springs and a sway bar.

Exactly, a wider and longer spring and a stiffer frame made the bean counters think it wasn't needed.

I added a hellwig rear anti-sway bar to my 2005, which is the same suspension as your 2102 (I have upper overloads, but they are never engaged), and it has been an improvement empty and loaded. I have yet to find a situation where I don't like the swaybar.

While the truck was very stable without one, it's on rails with it.
