Question:

Hello, I’m looking for a rear sway bar for my Chinook RV. It’s on a 1998 Ford E-350 chassis. There are several, options on the site for E350 class B, Class C, Cutaway, etc. I want to make sure I’m looking at the right products. Can you assist?

Hey Frank,

I can absolutely help!

Since your 1998 Chinook RV is a Cutaway E350 Chassis I recommend the Helwig # HE98RR. This is going to fit with no drilling into your frame. I have a Helwig swaybar on my '16 F-350 and man, what a difference. It really tightens up the feel when driving, my wife noticed it immediately before I even told her I put it on lol.

Where do you take your Chinook mostly, do you have a favorite camp site?
