Are the springs from McMastet Carr better than the one rayburn offers for there pull bar? What's the pro and cons of them besides there cheaper in pric

They are all basically the same, die springs are die springs. You can get them from any Stamping Die / Injection Mold supplier. McMaster Carr, PCS, DME, Progressive, etc. I would suggest giving PCS a try, since you are in Michigan. That's who I have always used for our mold and die components.

The different color is how they designate the different rates, or wire size. Of course the bigger the wire size, the "heavier" the rate, and the less % of maximum deflection they have. I am not familiar with Rayburn pull bar springs, but you can probably just match up the color, O.D., and free length to get the same spring rate. As cheap as they are, you could experiment with different lengths and wire size if you wanted to try a different spring rate.
