Which shocks stop the body roll?

[hotjag1]

My current motorhome is on a Freightliner chassis. Probably original shocks with 43,000 miles.

The ride is good, but going in and out of uneven driveways, the coach rocks from side to side, and leans more than "I think it should" around curves.
I have read many posts comparing Konis and Bilsteins. Most of the comments are in regard to which shock doesn't have a harsh ride over freeway expansion joints and provides the smoothest ride overall.

I don't really care how smooth the shocks are over expansion joints. I just want to get rid of the side to side rocking coming out of driveways at an angle, and excess leaning going around curves.

So, for my particular question, which is better. Konis, or Bilsteins?

Thanks everyone for all the replies. It seems that all the replies are directing me to take a look at the size of the sway bars and bushings, which I will do.

The odd thing is that my previous motorhome(American Dream)on a Spartan chassis with solid front axle did not lean very much or have the rocking and rolling going out of driveways. It must have had heavier sway bars.

The one big difference I noticed between a freighter chassis with a solid front axel and our current Spartan chassis with independent suspension was body role going in and out of drives and similar situations. I could not tell the difference between the two driving down the highway. If all is in good mechanical conditioning would put it all on the type axle.

Problem could be with sway bars. Check the bushings to make sure they are tight and in place. Verify size of your bar.
Roadmaster has good tech information for the bars.
Sway bars

Support, the O/Ps problem is a sway bar proble, NOT a shock problem.

Upgrade sway bar.. If you are out west Redlands or Brazil's do good work.

No shock will stop the body roll. That is not what they are designed to do. A good shock will slow down the roll and minimize the continuous rocking that the coach would have without the dampening effect of the shocks.
To stop the roll, your springs would have to be so stiff that your ride would suffer in all other conditions.
The shock is NOT a spring. It is a dampening fixture to slow down spring movement, but not restrict it.

Agree completely.
A shock stiff enough to keep your rig from rolling across driveway entrances would have it riding like a buckboard.

Our Monaco has an "almost active" rear suspension that does a good but not perfect job on those "big diagonals".

As mentioned above, shocks don't stop roll. Roll is controlled by sway bars. May need new bushings or a thicker, stiffer roll bar.
