Q: What does the A mean in the part number S5A-225?

The S5A-225 the ( A ) is for automatic. Designates the machine it went on at DFCI. Dimension-wise, they are the same. Southco purchased DFCI and own "Dzus" trade name.

Q: I am trying to cross reference a Southco PN D4-06-275 spring to your numbers.

It should be D4-S6-275 and our part number is S6A-275.

Q: What are the mounting hole dimensions of the springs?

.10 id and .647 center to center.

Q: I have mounting holes 1 3/8 center to center. What springs will work?

That would depend on what size studs you are using.

Q: What is the center to center of the S4-225? And were can I find all the center to center information?

3/4 of an inch. All the s4 will have the same center to center, just the height would be different.
