Hellwig #7254 for Sprinter 3500
I know there has been a lot of coverage on this matter already, but due to the age of the threads I am not permitted to comment. Some of you wanting to change out the OEM rear sway bar for a Hellwig ($156 at Amazon) may be interested to get a feel of how effective it could be. Since I don't have my MH yet and I don't know the diameter of the OEM bar, but I do have the 7254 bar (which is 1.5" diameter), I offer the following:
Since the torsional stiffness of a round bar is directly proportional to the diameter to the 4th power...this may give you a feel for it.
OEM Dia. % Stiffness of 1 1/2" Bar Compared to OEM
1" 506
1 1/16" 476
1 1/8" 316 (actual OEM may be no larger ???)
1 5/16" 171
1 3/8" 142
1 7/16" 119
1 1/2" 100
