Slash 4x4 diff

[backyard basher]

On the slash I'm replacing the rear diff.it came with traxxas grease.question is can i use fast eddie i use it on my hpi baja diff.or just stick to the grease it came with

Fast Eddie grease should be fine to use. I personally use Udder Butter from CowRC.com on my builds. I've also used Super Lube Synthetic. Some use Red-n-Tacky. All achieve the same goal.

I thought so thank you just was kinda unsure because of the thickness.
