Been looking for a set of torsion bars for my 1963 Plymouth Savoy drag car, [mine are bent]............The bars I am looking for are 30 degree offset, 41 inches long, and .860 diameter........I have looked at firm feel, and wildcat, with no luck, I am hoping someone in here might know where i can find a set...........thanks Tom What do you mean by 30 degree offset? The amount the ends have regarding twist ?

Did you get the bars you needed? I just got a set of the 1857775/1857774 from Bluestarperformance. They are a sponsor on here and the fellow was very good to work with. He even called me up to say they could not find the original set he had a picture of and wanted to make sure I did not care about the date code on them. Ended up shipping me a set that were the same part number and will work well for my application. Shipped to my home in just a couple of days.
Now my question to the group is this, why do I want these bars, .86 diameter for drag racing? It seems a bit counter intuitive to me that I would want the light weight bars, (I do not think it is about saving weight is it?). I would have thought you needed a heavier bar to help transfer weight back to the rear of the car on launch vs the lighter weight. Does the light weight flex more and improve the distribution front to back?
I just know the set that was in my car is mismatched and since the car launches with an extreme twist, I feel like these bars will help. I am just not exactly sure why!

It’s about weight transfer, light bars let the front rise so the weight transfers to the rear. Now if you have a lot of power and traction they can be too light for a specific application.

Think about two wound springs, one heavy the other light. Put enough pressure, say 5lbs, on the light one to compress it fully and let it loose, it's likely going to fly because the stored energy is high. Apply the same 5lbs pressure to a heavy spring, it won't compress as far and won't fly like the lighter spring when released. It's the stored/potential energy that matters in the transfer of weight situation.
