Re: Stock leaf springs preload when lowered
I was trying to let this go, but I'll take another stab.
When you assemble the rear end control arm assembly, you can put everything back together without installing the spring. This includes all the other limiting factors such as the shock.
When you install the spring with the suspension fully unloaded, you have to compress the spring to get the stock ride height adjuster to reach the spring. In theory, you could put a bolt there that is so long that you didn't need to compress it to reach when unloaded. I believe this is the "preload" that is being referred to.
But once you sit it on the ground, the spring is going to be under load despite the bolt length. You can shift the weight around using the height adjusters, but you can't remove it.
