Hello,
can anybody help me identify the identification of these spring numbers? I believe they are off of a 2004 Super Duty 4x4 dually. I tried cross referencing from other threads but haven't been successful to determine exactly what they are and their compacity.

front spring
3C34 ADA R 260 3 (Ford stamped number)
rear spring
R 265 3 3C75 DC (Ford stamped number)
Thank you

Maybe take them into the parts department at a Ford dealer- they might be able to identify them.
