One might think PC would order their chassis with a proper suspension...or have it done locally.
As the owner, you would have to do that.
A manufacturer doing that opens up a BIG bag of problems... the cutaways are sold by Ford as a 'federally approved' package that is deemed safe. ANY changes to suspension ( springs, shocks, swaybars) by the OEM (Phoenix Cruiser in this case) most likely would need to be re-certified by the appropriate federal testing agency to get federally approved. No manufacturer approval from the feds, and insurance becomes prohibitive/unavailable. Cant run a business like that today.

Takes time and several test units to be submitted for crash testing, etc.... $$$.
And honestly... the sale is over before the owner gets to understand the shortcomings, so why add $$ to the sale price?
As the 'end user' we as owners can do whatever we want to the chassis and drivetrain. ( Not saying that you would be immune from prosecution later in an accident should your work be at fault, but you would not have the same 'hoops' to jump through that OEM 's do to get it registered after your changes) (and I imagine CA residents might have a lesson or two about the smog testing hurdles..

)
I know I risk sounding like Ron and slides, but putting front springs that were the proper rate and height for my application worked wonders. Instead of putting 'band aids' on the other systems, I just changed the incorrect one. Night and day difference in ride and handling. If I want to gymkhana or road race it maybe more will be needed.
Though I would of thought that the stock steering stabilizer and shocks would have stood-up longer than 27,000 miles or 2.5 years also. Looks like they were engineered for a 2 year warranty.
