Lowering the rear in a 69. Question

I did a search but I didn't see what I was looking for. Before buying new leafs, I thought I'd ask how much lower would the rear be by removing 2 leafs from a 5 leaf spring? I have traction bars so I would figure 3 leafs and traction bars would stop wheel hop.

Re: Lowering the rear in a 69. Question

I would think it would be the thickness of the two springs,just like changing the thickness of a lowering block, and then any additional sag.

Re: Lowering the rear in a 69. Question

By removing the springs (leaving your clamps off) you can adjust the rear height and then clamp the leafs in that position. But be aware of where the rear shackles are so you don't cause damage to your inner rear and tail panel.

You add a block above the spring stack to lower the car. Removing springs from a spring stack has to come from below the top spring with the spring eye so the only change in height comes from changing the spring tension as you remove leafs from the stack.

You'll also possibly bottom out much easier. The correct method is de-arching or replacements. If you are only looking for an inch or less, I've used a 1" lowering block with good success.

I don't believe the clamps or bands around a multi leaf spring stack have anything to do with holding the spring shape or spring tension. The bands just keep the leafs in the stack from twisting.

This is too arbitrary of a question, how worn the springs are already, who makes the springs and what the initial spring tension of each leaf in the stack will have a factor in the final ride height.

As well changing the spring tension (sprung weight) by removing springs from the stack will effect the handling and ride quality.

Some generic Autozone 5 leaf replacements that were installed 10 years ago. Don't know the rates. On average.. is the cost of dearching them close to just buying the Hotchkis for $500?
