Installation Tips

This spring has an eye-to-eye measurement of 52". The way to measure a spring is on the inside contour of the spring from the center bolt to the center of the eye. On this spring, when you measure from the center bolt to the eye on both ends of the spring, it is 26". 26" x 2 = 52". If you measure eye-to-eye using a straight edge, it measures about 49", but that is NOT the industry standard for measuring springs.

The Wrong Way To Measure Leaf Springs:

The wrong way to measure springs is eye to eye. You know, taking the tape and measuring the spring straight from one end to the other. It’s wrong because springs flex up and down depending on the weight applied, which changes the length of the spring a different amount depending on the spring’s rate (and whether it was properly built.) So that method doesn’t tell you your spring’s size at all. Worse yet, it also doesn’t tell you where your center bolt is located. The location of the center bolt is where your axle and spring meet. Do I need to stress the importance of making sure your spring is connected to the axle correctly? No? Oh, good.

The Right Way To Measure Leaf Springs:

You need to measure the spring as though the spring were flat. Relax, that doesn’t mean you need to learn advanced calculus. All you need is this handy picture and your own trusty measuring tape.

Divisional Length

Follow the curve of the spring, measuring from the center of the front eye back to the center bolt
Then, measure from the center of the other eye back to the center bolt
Record the length like so: “24 inches x 24 inches” or maybe “21 inches by 27 inches,” depending on your measurements and center bolt location

These measurements are called the divisional length.

You see, when you give the length of a spring as two lengths going from the center of each eye to the center bolt, you kill two birds with one stone and give us the location of the center bolt as well.

Spring Arch

Spring arch is measured by splitting the center of the spring’s eyes with a straight edge. (Grab a yardstick or anything you can reasonably call straight.) Don’t try and flip your spring upside down and measure that way. I know it feels clever, but those pesky spring eyes just won’t let you do it. So take an extra step and measure it this way. Your ride deserves it, right? Measure from the line created by the straight edge to the main plate right next to the center bolt. This is true no matter which way the spring is bending. So don’t fret if you get a negative number. It’s ok. And that’s all! That’s all it take to measure springs the correct way. See, that was easy now, wasn’t it?
