Just because they are pretty expensive, I was wondering, if you could only get and install one at a time, would you get the Helwig front or rear sway bar first? My coach is a 2006 E450 Super Duty /...
I did a front Hellwig bar only. Made a significant difference. Completely agree the OEM bar is barely suitable for florist deliveries in E150's.
Monroe also makes an RV Magnum shock for the front. Cheap, and like them better than Bilsteins, as the digressive valving the Bilsteins have allows too much low speed shaft travel, cupping the front tires badly.
