Replacement Poly Bushings for Rear Anti-Sway Bar on a 2011 Tiffin Allegro on a Ford F-550 Chassis

Question:

I have a 2011 Tiffin Allegro MH with F550 chassis. I measured sway bar and it is 1-27/64inch in diameter. Will this kit work? I found lower bolt on driver side missing form factory bushing.

Rear poly bushing kit # RM-4139-125 is indeed a fit for your 2011 Tiffin Allegro built on a Ford F-550 chassis. Roadmaster notes that some of the endlink parts may not be used in the installation and that the fit assumes a 1-1/2 inch OEM bar.

Your bar at 1-27/64 inches (1.42 inches) is very close but ultimately too small for a proper fit and you will need a different option.

The other option is # RM-4139-300 for a 1-3/8 inch diameter bar. This is actually closer to the 1.42 inch bar you have than kit # RM-4139-125 for 1-1/2 inch bars.
