I’m posting to this thread to correct the content for future “bolters”. A fellow “Bolter” PM’d me, saying he had the same overload springs and was happy to find it was a factory installed option RPO254 as concluded in the original thread. He also said his only had six leafs instead of the nine as the RPO stated. I had just removed mine as they needed to be cleaned up and painted. I took some pictures and noticed mine also only had six leafs. This prompted me to revisit the original post and look at the
1952 Chevrolet Specifications that showed the Options. Sure enough the RPO stated that it had nine leafs. It was then I put two and two together and realized that the RPO254 more than likely added one additional leaf the the spring stack of eight increasing the load capacity of the original springs from 1,450 lbs to 1,730 lbs each and it was not a set of second stage overload springs.
So now I’m curious, what do we have? Are they factory option or aftermarket?
