Hot Racing Traxxas Slash 2WD Sealed Aluminum Differential Case
This was one of the better upgrades for the slash. To prevent leaking, build it using protek orang grease or associated green slime. I use 20k oil and the truck feels great. I use this in a lcg slash with a 3600kv castle motor.

Hot Racing Traxxas Slash 2WD Sealed Aluminum Differential Case
I didn’t use grease but used 100k Fluid. Leaked a little and needed top up but diff casing is solid.
