What I want to know is what are the benefits of a diff locker? And a slipper clutch delete? I have the stock diffs in my cars, as well as the stock slipper clutch system (minus HR Aluminum pads) and it works well for me. Pros and cons?
True but not true.
I'm not to scientific into lube and greases. I just use what other people use and what the manual says. Like @Chubaka said, Traxxas says white lithium but it dies up quickly.
That red and tacky stuff, or anything similar to it can be used for anything else. 1:1 Wheel bearings...
I use Red synthetic grease. from Mobil One. Same thing as red and tacky or lucas oil. I use that in my B74 gear boxes, and rusty planetary diff. Or standard black grease can work, but red and tacky is a bit thicker...
