I know it's not necessarily vintage but could someone measure the diameter if the springs used on AE RC10B6.4 13mm shocks please? Part number 91947, 91948 or 91949 and possibly others.

I'm looking for springs with about a 15mm diameter, 60mm length and 2 lb/inch spring rate to use on the front of my Blackfoot on the yellow oil filled option shocks from back in the day. The softest springs I have are still far too stiff and they're about a 2.5 lb/inch rate.

Thanks in advance for any help or other ideas.

If you can find some older Losi springs, they fit. Any of the big bore stuff will require a spring collar and different cups.

Any idea what model Losi?

I do have some springs that are Traxxas "Big Bore" spring that I believe are for E-Maxx and T-Maxx, part number 4649R. Good diameter, bad length and bad spring rate (2.5 lb/in.).

The older 90's, early 00's standard bore stuff. The bright powder coated ones.

The Traxxas "Big bores" are actually smaller than their standard ones. They are all fairly long and heavier rates. Many people used Losi springs on them, back in the day.
