I bought this in a garage sale way back when, Nissan stock springs part number 55020-E4102.

Lots of pics in my gallary. I was talking with Carl and he thought the measurements would be of interest. I made the measurements pretty quickly.

Wire diameter - between 0.451 and 0.457 inches depending on where I measure it. This is coated, so probably less than 11.5 mm underneath the coatings

Spring diameter (outside edge to edge) - around 4.441 inches.

Unsprung height - 14 3/4 inches.

Coil count - I'd say about 10.6 coils...

Hi Lee:

Thanks. That is pretty much the spring spec.'s we used to have the OEM Stock springs reproduced.

FWIW,

Carl B.
