View Full Version : Leaf Spring Dimensions

Anyone know the spring measurements for a 67 that came with a 440/Hemi? Local spring shop says they can make springs, they just need the measurements. They have 3 listed springs for this year, but it's not associated to drivetrain config.

The ones I have on the car are not the most reliable ones to use for a template.

Hello Mike,

Here are the rear leaf spring specifications from my 1966 Factory Service Manual. I'll get the same information from my 1967 FSM and will post it here soon.

OK, for 67 B-body with 426 and 440 engine you have a 6 leaf on the left and 7 one the right. The arches are the same for both sides.

5 and 7/8 inch free arch. Which is off the car, put a straight edge from center of front eye to center of rear eye and measure to the top of the top leaf, not the bolt. But you measure at the center bolt, not the middle of the spring.

The measurements from eye to eye are as follows: front eye to center bolt is 22" following the spring arch not a straight line.
center bolt to rear eye is 36" following the spring arch not a straight line.

Just some pictures to help with Rich's description.

Measuring spring arch. If you don't have a straight edge 5' long, Run a string between the 2 spring eyes.


Then take a ruler and measure from the top of the spring to the string. This measurement is free arch.


From eye to center bolt, lay tape measure on spring and measure from center of forward eye to center of center bolt. Repeat for rear segment.
