Name that shock!

Hello,

I purchased a used Revo 3.3 roller a year or two ago on Ebay. I converted it and life has been good, until I stripped a shock end on the front a couple weeks ago. As it turns out, the previous owner fitted a pair of shocks that I've never seen before. I cannot identify them and neither can my LHS. This mystery shock was equipped with a traxxas shock cap, spring retainer, bumpstop, and spring, so it is kind of a hybrid.

I'd like to know what they are so that I can purchase a new shaft. Do you guys have any ideas? Thanks for your help!



Note the dual-rate piston setup. No, this shock end is not stripped. It's on the other, non-pictured shock.


This one compares the mystery piston to the standard GTR setup.


Note the provision for the dual rate piston provided on the mystery shaft. The shock shaft below is the GTR one. It is too short to be used in the mystery shock. I would forfeit the dual-rate piston if the shaft were long enough, but it is not.
