I respectfully disagree when it comes to using
this turnbuckle and rod as a component of a spring spreader.. Even though turnbuckles are used 'in tension" it would take a tremendous amount of compression force to bend the 1 1/2 inch dia. rod. And, if the turnbuckle loop was "boxed" it would not spread, for sure. If anyone has used a Port-A-Power with a psi gauge to spread a 1940-48 car spring please let us know how much force was required Here's an interesting chart.

Here's an interesting video. Notice the small dia. of the rod where it fails. Just imagine what compressive force would be needed if that rod was 1 1/2 in. dia.

Plus, I have also seen photos of a turnbuckle jack which incurs compression forces in it's use. For example, here''s amotorcycle jack.
