Question:

Looking to upgrade the suspension, only have 3000 miles on unit. It is built on the F550 Chassis, 22,000 lb GVWR package. Front bar is 1-1/2 diameter now and rear is about 1.35 diameter. Want to make sure I order the right parts. What do you recommend?

Expert Reply:

For suspension upgrades with this type chassis my preference is to suggest starting with the front and rear anti-sway bars followed by a steering stabilizer.

For the 2019 Holiday Rambler Admiral Motorhome on an F-550 Chassis, I suggest the Roadmaster Front Anti-Sway Bar # RM-1139-148. This has a diameter of 1-3/4" and constructed of thick 4140 chromoly steel for superior strength over that of the OEM installed bar. It is not just the slightly increased diameter of the aftermarket anti-sway bar over that of the OEM that improves handling, but that of the 4140-steel used and the improved polyurethane bushings.

For the rear of vehicle, I suggest the Roadmaster Rear Anti-Sway Bar, # RM-1139-149. This is a 1-5/8" diameter bar constructed with the same 4140 chromoly steel and polyurethane bushings as that of the recommended front antisway bar.

For further enhancements to your motorhome the next steps I suggest would be to consider replacing the factory jounce bumpers and possibly installing rear airbags. But I would start with these three items first and then evaluate afterwards.
