Heavier Rear Sway Bar ML350
 

I’m having trouble finding what is available as a heavier rear sway bar for an ML350. I’m looking to buy an ML350 but I want to make sure I can remove a little of the under steer before I buy one. A rear sway bar would be the ideal solution but when I shop with google it always comes up with a bar for some other car.

Thanks in advance for any suggestions.

I suggest you just hook up your trailer and try it out before altering the factory bars. The leveling hitch should take much of the bother out of towing. An anti sway hitch will do the rest if the leveling hitch is not enough.

Putting on a heavier bar in back might get you into oversteer when cornering.
