Recommended Sway Control and Shock Absorption for 2021 Thor Magnitude 35bb with F-550 Diesel

Question:

These will go on a 2021 Thor Magnitude - F-550. I am ready to place order - however - #1 - I need to add the roadmaster steering stabilizer. Please let me know the correct item number for this. #2 - for the front sumo springs - would the 2 piece work better for me than the one piece you originally recommended? SumoSprings Rebel Custom Helper Springs - 2 Piece - Front Axle Item # SSF-170-40-2 please advise asap so I can get all ordered. Looking to lose the sway and smothen out the ride the best way possible. thanks

For your motorhome, the tire pressure should be whatever the manufacturer recommends which should be in the door panel sticker or your owner's manual.

It doesn't surprise me that the sway is the biggest issue because that is a very common issue with motorhomes. The Roadmaster Rear Anti-Sway Bar # RM-1139-190 is the correct fit for your chassis and will do the most out of any products to help control the sway and improve the overall ride. The bumps in the road are a frustration, and the amount of weight on the chassis is likely why you feel so much. I recommend using the SumoSprings Solo Custom Helper Springs - Rear Axle # SS54VR and the Front Axle # SSF-111-47. These springs adjust with the load and help with road shock as well as reduce body roll. The combination of these parts will dramatically improve your ride.

For your 2021 Thor Magnitude there isn't currently a confirmed steering stabilizer fit. The SumoSprings Rebel Custom Helper Springs - 2 Piece - Front Axle # SSF-170-40-2 you asked about are not a fit for your F-550 chassis. Those springs are designed for the full F-53 Coach frame and there aren't currently any in that style confirmed to fit your frame. I recommend staying with the SumoSprings Solo Custom Helper Springs - Rear Axle # SS54VR and the Front Axle # SSF-111-47 which are the correct fit for your vehicle. These paired with the rear anti-sway bar # RM-1139-190 we already discussed will be a big help. Because this is such a new vehicle, I recommend checking back for the front anti-sway and steering stabilizer as Roadmaster is working toward these fits.
