Front leaf spring

Post by Cschaff63 » January 17th, 2019, 5:48 pm

I ordered a front leaf spring from Mac's, the tech told me that the A and AA were the same part#. Well, when it arrived, it is 1/2" skinnier in the width, as are the shackles. My truck measures 2 1/4" wide, the new spring set is 1 3/4". Can someone clue me into what I'm dealing with here. Bob C has informed me I have an early 1930 truck and not the 28 I thought it was! I called the Mac tech again and he insists the springs are the same! Help!

The 1928/1929 AA chassis used a front spring which was the same width as the A chassis (but not the same spring). Starting January 1930, the AA used a front spring which was the same width as the A chassis rear spring.

I suggest you know what you need before taking to a vendor tech. Same goes for buying of Ebay or other. Sellers don't know the facts many times.

Mac's doesn't have a clue. "A" Springs has the one you need. http://www.a-springs.com/4b.html

Neil, up until I got to the chassis parts, I thought I had a 28, everything I have ordered from Mac was spot on, but since learning this is an early 30, it changes the game on everything under the body! But you guys are an awesome source for the knowledge on these trucks. I love these old trucks and feel proud to have brought back a piece of American history. I'm addicted,

I just looked in the parts book and the 14 leaf spring is for the long wheel base chassis, 13 leaf is for the short.

I'm trying to figure out why my truck only has 10 leafs, the first 3 on the bottom are much thicker than the top 7, if I put a 13 leaf on it, it will Jack up the front end! I think I will just take mine to the local spring shop and have them replace the broken leaf and refresh the set with new bushings.

I measured some springs, the 13 leaf was 2 5/8" and the 14 was 2 15/16".

Mine measure 2 1/4", Are you talking about the height of the stack or the width of the leaf?
