Building e-maxx basher - Need Guidance

[steve050773]

Hey guys - longtime lurker first time poster.

I am in the process of getting a used UE lightning chassis and starting the process of building up a bullet proof basher e-maxx.

Throwing money out the window, and ignoring the motor/controller for now, what would you recommend for the ultimate in durability?

Here are some things I'm thinking:

UE Lightning chassis
Either Great Assembly 7075 bulks or UE VBS?
RPM Arms (If Rpm arms what shock towers?), or UE EXT?
UE Servo saver
Hitec (5955tg I think 300oz) or JR9000t steering servo
Gmaxx single speed (I don't really ever shift the maxx I have)
UE steel/titanium cvds all around
RPM bumper
Gorilla or UE skids
RPM skid guards (or whatever they are called)
Lunsford Ti rods, pins

Where I really need help is

Differentials (worth upgrading? I haven't had issues with my stock diffs in my maxx)
Rod ends, Pillow balls?
Screw kits?

I know I'm missing some smart ideas or upgrades. Let me know your opinions!
