What’s ‘AV’ in Pinion Discription

[Re-Bugged]

Would someone be able to tell me what the the difference is (if any) between a pinion that is listed as,

1, 0.6 mod AV

2, 0.6 mod

Its mainly for pinions in an M08 chassis, and an SRB chassis.

Thanks for any advice 👍🏻

None.

Tamiyas AV was an acronym for Avante.

It was one of the first to use a 0.6 mod pinion I believe.

I wondered if this might be the case and sounds like the most plausible answer - tamiya has a habit of naming a part after the first car that used it, even if later ones also use the same part, e.g., 'skyline speed-tuned gear set', 'skyline long front suspension set', 'manta ray ball diff set', to name a few.

What about all the SRB's?
