I'm looking to replace my scrt10 with a 4x4 sc10. What else should I order with the truck. I'm going to use the same electronics that's in my jammin now. Mmp, bec, novak 4.5 550, 9351 servo. So just mainly need to know what I should upgrade right out of the box? Diff/ shock oils? Also im a pretty clean driver but what parts should I keep on hand?
