The stock steering damper installed by Ford on their assembly line, is severely under-rated for a motor home application.
Some years ago, I got PDF files of all E-series chassis specs during the time when Ford built the E150 van, E250 van, E350 van, and various flavors of the E350 & E450 cut-away and stripped chassis. I was negatively surprised to learn how many parts like shock absorbers, steering stabilizer, and front stabilizer bar are identical regardless of the application. That is strong support for upgrading those components to better match a motor home application.
As I recall for 2007......
- The steering damper and front stabilizer bar on an E150 van is the same one installed on an E350 & E450 motor home chassis.
- The four shock absorbers on an E250 van are the same ones installed on an E350 & E450 motor home chassis.
- A 2007 and older E350 chassis, has NO rear stabilizer bar unless the motor home manufacture or previous owner installed one.
The information explains why our 2007 E350 PC-2350 handles so much better with the suspension improvements we made after taking delivery.
Comparing the specs on 2008 and newer model years are not much better. The E350 motor home chassis did get a wimpy rear stabilizer bar which is better than nothing at all.
