What is the Correct Front Anti-Sway Bar for a 2011 Class C Motorhome Built on E-450 Chassis  

Question:

I received two recommendations for a front anti sway bar. RM 1139 147 and RM 1139 179. I have a 2011 Thor Siesta class C motorhome with a V10 on an E 450 chassis. Which one is correct? Thank you.

Helpful Expert Reply:

The Roadmaster Front Anti-Sway Bar, # RM-1139-179 that you listed is a confirmed fit for the 2011 F series chassis not the E. The # RM-1139-147 that you list is for the "E" series but is rear anti-sway bar not front. It appears that when you selected from the fit guide, you selected the "F" series chassis instead of the Van option that will list the "E" series components.

For a Class C built on the 2011 "E"-450 Chassis:

Roadmaster, # RM-1139-147 is the correct Rear Anti-Sway Bar
Roadmaster, # RM-1139-176 is the correct Front Anti-Sway Bar
