I am currently on an FLM extended low cog TVP Mid tank savage on stock suspension. One of the things I noticed is how the rear hubs are tied together, very similar to that of a maxx. The ball end is screwed into the rear bulkheads seperate from each other. However this leads to your rear hubs being able to wiggle back and forth rather easily making it sloppy. As you probably know, a tighter more rigid truck handles better. To fix this problem I built a simple brace out of aluminum that locks the rear turnbuckles together. The result is a slop free rear end.
Enjoy.
Enjoy.
