Arrma 1/8 scale preload spacer

thingiverse

Preload spacers designed specifically for 1/8 Arrma vehicles are now available. On the Kraton, Talion, and Outcast models, the rear springs prove too short to generate any significant preload when paired with the threaded collar. To overcome this limitation, these spacers will be inserted between the threaded collar and the spring, effectively creating a bit of much-needed preload.
