I finally made a easy to read spreadsheet for 1928-1948 Ford REAR leaf springs.
We can make any of these springs and supply mounting hardware as well.
Custom made in the USA to original stock specifications or custom specs
to raise, lower, softer or firm up the ride of your Ford.
We also supply front springs, rebuild lever shocks,
and supply American made front end chassis parts
and rebuild steering gears.
