Traxxas GTR Shock Spring Set (Green - 1.92) (2) (1/16 E-Revo)
I'm trying these on a 1/16 Slash and they seem to work as expected. I put these in the back of my mini Slash with the Black 1/16 E-Revo version of the springs up front. It seems to droop a bit in the back, but I'm sure I can adjust the suspension a bit more as needed (springs, preload, oil weight, etc.).
The hardest part is working out the right springs to get and where to place them!
