New Leaf Spring liner

[Ed D.]

After about 30 years and a long Road Tour from NJ to the National in Mobile, I have decided to have my 1972 trailing arms rebuild. While I am under there I figured I would rebuild my original leaf spring. Are there any liners that fit or are better than others?

Re: New Leaf Spring liner

Quanta liners are probably the best available. Visit their website.

PS: For trailing arm rebuild, use Bair's or Gary Ramadei.

Thanks Larry, plan on using Bair's for the TA as I have their shipping containers. I will check Quanta liners. Any suggestions on liner assembly?

Stick with Bair's on the TA's AND LINERS!

Re: New Leaf Spring liner

Ed, Make sure to measure spring total thickness at the differential mounts before, and then after assembly with new liners, which are often thinner. It could affect the 4 bolt lengths and you may need to shorten the 2 forward bolts.

Also, when using a new spring center bolt, check head height as replacements are typically too high.

Excellent advice.

Re: New Leaf Spring liner

Is is typical to have to trim the liners to fit?

Re: New Leaf Spring liner

I had to trim the liners from Quanta, also six months ago I enquired on another set of liners and they were out of stock.

Since we're talking about leaf spring liners, I thought this may be of interest.
I was able to come across some NOS liners and measured the thickness. I compared the thickness to a set of liners from Eaton (leaf spring manufacturer).
The NOS were .0450" thick and the Eaton were substantially thicker at .078"

Joseph,

Over the years people have reported a substantial variability in the thickness of the liners. Including differences between GM production liners and GM service replacements.

Here is info from two posts from the archives:

Re: New Leaf Spring liner

Thanks Gary,
In other words, they are all over the place in thickness!
I was super excited to have found some NOS liners. I noticed there is a difference in the actual composition of the NOS and the Eaton liners.
The Eaton appear to just be extruded plastic?

On a side note, would you mind if I PM you regarding a leaf spring question?
