Thread: Spring question.

Tweet

The spring measures 37 1/2" from eye to eye. The axle is 54" from king pin centers.

Jerry ive seen these axles used before in this configuration. Is there a design issue i should be aware of? other that radius rod fabrication?

Jerry, I don't believe the spring configuration is wrong here. The axle doesn't have a clue to spring location, nor does it matter much. Those old truck axles have been used in cross spring applications for over 60 years. And after you cut off the stock axle pads, this axle will be like any I-Beam axle.

Now Jerry I'm not trying to rain on your idea and if you have a reason for thinking the axle won't work I sure would like to hear it and learn.

You're home brewin' your own deal here, but I'll use stock Ford stuff as an example. Typically the perches are a nominal 4 inches wider than the spring "at rest" as you show it off the car. The typical shackle is 1 1/2" bolt to bolt, so when you mount the spring without any vehicle weight on it the shackles are parallel with the ground. Once weight is put on the setup they should be at approximately 45 degree angle. Here's a graphic I clipped from Posie to save a thousand words.
