Im referring to physical weight of the shifter above the pivot point. That adds to the inertia which helps give momentum and dampening when slipping into gear.

This is something I might play with by pouring lead shot in to the shifter tube, which happens to be hollow. I can calculate approximately what ratio the weight needs to increase by looking at % change of the shifter ratio.

Might be a good excuse to go to pick a part and pick some gear knobs of different weights.

I'm fairly sure the shifter shaft on my VN was solid steel and fairly heavy at that. I retained the factory shifter shaft and knob so the only thing changed with my was the shifter pivot.

Another way to compensate would be to fit a slightly longer shifter shaft.

They are hollow with rubber in the bottom half for dampening. They are not heavy at all. Lot of OEM these days deliberately weight the knobs, typically around 200-300g

I don't remember mine having rubber on it full stop. I think I might still have one lying in the garage, if I find it I'll confirm.

all mine are rubber filled. I had them sand blasted and you could see the rubber at the bottom of the tube.

I'd say all Holden floor shifters have the rubber in them, Aussie 4 speed onwards did and the original shifter on my t-56 did before I put the hurst on. I wonder if the rubber is to dampen or soften the hammering on the stops if you drive a bit on the spirited side

I made a stick and knob all out of stainless. Plenty of weight. No rubber filled either.

For dampening, there is give when you push hard on them. Also I can hear the hissing sound of the teeth come from the stick and knob so that would dampen it some. The sound would be louder if its solid I reckon.

^ Dampening makes it wet, damping reduces vibration...

Some places make proper weighted knobs, often as part of the whole shifter package so they're nicely balanced. I made a knob out of an old tow ball for the TKO!

That's not to say Vlad is incorrect. It all depends in the subject matter. ;)
