I run one on the front of my 32 roadster.

It replaced a Posies so I could gain a little more suspension travel.
Nothing wrong with the Posies, I liked it, but since I didn't notch the frame front, travel was limited.

The Durant Mono-Leaf added travel and the car didn't sit up any higher than before.

Over the years, about 11 or so, the Durant has sagged.
To be expected perhaps, but it could also be due to being heat soaked at 400 degrees F during the powder coating process.
The powder guy said there wouldn't be a problem, but I note that some tempering of metals - specifically differential gears - is done at 200 degrees F.

That leads me to believe that being exposed to 400 degrees isn't such a great idea where springs are concerned.

Paint next time.


And the Posies Super Slider is on my 31 roadster.

Waste not, want not . . . or something like that....
