Front and Rear SumoSprings for 2012 Thor Challenger 36FD Motorhome

Question:

Need confirmation of what part number will fit my Challenger before ordering. my coach GVWR is rated at 22000 lbs. Somewhere I was reading that the F53 chassis on my Challenger that one part number would not fit due to the rear chassis wiring and plumbing. Could you please help me with this issue, so I can purchase the Sumo Spring.

Thanks for checking in! I'd be happy to help you out with what SumoSprings you need for your 2012 Thor Challenger 36FD.

The front set is part # SSF-170-40-2 while the rear set is part # SSR-187-54-1.

Some models don't fit certain motorhome models so it is always best to double check. I have attached some installation videos on similar year F-53 chassis that you can check out.
