Thanks for the info. Measured correctly and they are about 56 5/8" which seems to be trail gears springs.
I don't think there Tg springs, Trail Gears have a military wrap, yours don't, the clamp on tg springs are closer to the eye and have a anti wrap leaf under it (half leaf), yours don't.
Im still leaning toward those being f-150's. How wide are they? Tg springs are 2 3/8", most of the domestic trucks (ford,chevy etc) are 2 1/2".
