It still doesn't drive right.....
So, the last thing we can try is the sway bars. We're researching that right now.....
Some rigs handle fine without upgrades. Others not ideal but acceptable. Still others like you, find the handling unacceptable.
Given your dissatisfaction with the handling, I would invest in both a front and a rear heavy duty stabilizer bar. The bars are thicker and come with polymer bushings. Helwig and Roadmaster are 2 of a number of popular brands. Whatever brand you get, be sure they meet or beat this basic criteria.
Rear Bar
- 1-1/2" bar diameter
- polymer bushings
Front Bar
- 1-3/8" bar diameter
- polymer bushings
The stock E450 rear bar is 1-1/8". The extra 3/8 inch doesn't seem like much, but it makes a huge difference along with the more rigid polymer bushings.
The same applies to the front stabilizer bar. Stock is 7/8" to 1" pending E450 model year. The heavy duty bar is 3/8 to 1/2 inch thicker.
Our 2007 E350 chassis rig has heavy duty stabilizer bars along with other handling upgrades like a rear trac bar, heavy duty steering stabilzer, made-for-RV shocks, and a good wheel alignment as well. The rig has handled beautifully ever since, even when conditions are not so good. Five years running and all is well.
