Sway Bar Recommendations for 2017 Thor Challenger Ford F-53 Motorhome


I have a 2017 thor challenger motorhome. F53 chassis. 37 foot. V10. Does part no. 1139-140 and 1139-144 work ok? Any extra info. you can send for these torsion bars will help.


Helpful Expert Reply:

The Roadmaster swaybar part # RM-1139-148 is a confirmed fit for your 2017 Thor Challenger on an F-53 chassis.

Then for the rear sway bar you would want the part # 1139-144 that you also referenced. These are both fits for the V10 models of the RV like yours as well as ones longer than 34 feet like yours.

Sway bars are great options to improve the overall ride quality and driveablity of the F-53 chassis RVs. Typically people see the biggest improvement with the rear sway bar and next with the front sway bar.

I attached install videos for both sway bars for you to check out as well.
