Why are There Two 1-1/2 inch Diameter Roadmaster Sway Bars for 2017 Ford E-350 Cutaway

Question:

What is the difference between the rear sway bars RM-1139-117 and the RM-1139-198? I have a 2017 Ford E350 cut-away chassis and both are listed to fit my RV.

The reason there are two 1-1/2 inch diameter Roadmaster sway bars that fit your 2017 Ford E-350 is that the # RM-1139-198 is for versions of the vehicle that have automatic snow chains that deploy and the part # RM-1139-117 is for the versions that do not have the chains. So based on whether you have the snow chains is how you'd pick which set to go with!
