The simple fact of the matter is that the first owner was shortchanged Walt.
His springs weren't big enough for the job.
'Nuff said?
The Mad Springs solution is a nice one.
I just checked their site, nothing listed before 2000.
Air bags, the very best way to go.
800 quid for a 2000 Transit Transit.
There's a guy in Herefordshire selling at £500.
If you fill the bags with a footpump / electric tyre inflator, you'd probable get down to 3 to 4 hundred.
Let me know if you want to go that way.
I doubt cheap springs are worth fitting.
You can get used heavy duty springs for 300 Euro the pair if you wish.
My money says your helpers were made by Grayston, am I right?
Money down the drain in my book.
I think the most cost effective way is for you to upgrade your present springs.
The problem isn't very technical, so you don't need a technical solution.
Just good old blacksmith engineering.
How wide are your your rear springs please?
Do you know anyone who will flog you a pair of LWB rears please?
