If it is relatively flat end to end then it needs to be replaced, it has lost it's functionability. Monosprings are a good replacement for these; lighter; many different spring rates.
Yup, left side done.
I think anytime that the springs start to splay out a little bit. It’s probably time to get rid of it. I noticed it with two of my previous springs and then when I finally got a new steel spring, they don’t splay out anymore, but perfectly lined up.
Could you please describe the improvements between the fiberglass mono spring vs the stock steel spring?
Thanks
43 lb weight savings. Anecdotally, may last a lot longer. Linear spring rate with minimal internal damping, so you'll need good shocks (Bilstein sports, or adjustables), but suspension absorbs bumps, not leaf friction.
Be sure to get a VanSteel low-arch spring if you go this route.
Thanks for the heads up. Read that post while doing research. Already ordered the 8" bolts.
i didn’t need different bolts, hoping you dont either.
I ordered the gymkhana spring as i converted entire car and was much lighter than 9, if that lower matters as a priority,
bushing time too..
this thread is when i went original 9 leaf to 6 used gymkhana.. https://www.corvetteforum.com/forums...questions.html
good luck!

With the weight of the heavy rear spring hanging out below actually works well for my 427 equipped C3. The weight of the original spring helps keep my BB C3 better balanced. I am not sure pulling 43 pounds from the bottom of the rear of the car would actually help my balancing act.
While rebuilding the Differential we took the rear spring out pulled it apart, sand blasted it, painted it and reassembled it with new rubber spacers and lots of grease. This did not take long and the spring is still there after 57 years the spring is still doing its job and looking good. It is a spring...
Just throwing this out there. I had stock springs and went to the Daytona suspension from Chevrolet. It was a bit too stiff for the rubber I was running back then.
I called Dick Guldstrand Enterprises. To my surprised Dick Guldstrand answered the phone. We had a long conversation about rear spring. I was leaning toward a monospring. Dick talked me out of it. He mentioned he could run any spring he wanted to and could sell any spring he wanted to and felt a metal spring was the best choice. I remember asking him about the monospring minimal internal damping. He said the internal friction of the metal spring was an asset.
The problem with ordering parts before disassembly is you always need more parts. Spring bolt cups for the trailing arms are shot so they have been ordered. The new spring is 7/16" thicker then the original so need new mounting bolts for the diff mount. At least the new shocks went in easily.
