I have 0% Punch because i love having full power.
My truck at the moment weighs 14lbs and geared for 52mph on 6s.

This is probably the punch line. Your at that fine line where something's gotta give. In you case, its been the pinions. If you do in fact find a pinion that's strong enough to not strip, you may end up with issues somewhere else. Shear strength is a factor of material strength and cross sectional area - I haven't gone back in the the threads to look - are you running mod1 or mod.8? You probably need to be in Mod1 if your not already.
