And how does that actually help? To stiffen a leaf spring, you need to add more leaves, right? If not, then how do you stiffen a leaf spring without adding leaves, or at least half leaves?

I tried measuring the distances but either it was insignificantly small or my method was too crude, so nevermind!I wish I could find that post that made me ask this...

Weight Jacking…
Should help out no matter what you drive around in (as long as it has a solid rear axle), because under heavy acceleration drive shaft torque lifts the right rear tire. A stiffer spring on that side helps out, or you can preload it with an adjustable sway bar.

That makes sense. Thanks for posting that. But, as asked before, how do you stiffen the right leaf spring without adding extra leaves?

Excellent picture bentworker. Wouldnt it make sense to have the left wheel be the drive wheel instead of the right, since the left gets pushed into the ground unlike the right lifting off?

A leaf with more arc to it doesnot have a higher spring rate, but it will be compressed more than the leaf with less arc (and same spring rate), causing it to carry more of the weight. An example would be if you had two rear springs that had a spring rate of 200 pounds, and the passenger side had 1” more arc, so to compress both sides to the static ride height the passenger side may be carrying 600 pounds of load, where as the drivers side (which is compressed 1”less) is only carrying 400 pounds.

Baddog on a non posi car the wheel that spins is the wheel with less traction. Thus the right wheel will usually spin because of the axle torque.

So, are you saying the tensil strength of the right side leaf springs is somehow different, even though there are the same number of leaves? Do they forge the springs differently so the strength is stiffer?

Soaring

It makes sense that if you have a stiffer spring on the passenger side, and the only way you can have a stiffer spring is to add leaves, then the passenger side would be higher than the driver's side. I think you guys are full of hooey. The springs on my car are the same as you can see by the ride height being level from left to right.

Ahhhhh, I never understood why it was the wheel with the least amount of traction that spun, I always thought that was a stupid idea. You've opend my eyes...
