Optional Low Range Gearsets

[Mjh2157]

Hi,

I'd like to change the low range gearset on my trx-4 to slow it way down and add torque (very scale running). I searched through traxxas's catalog of gears and I don't see anything compatible to change them. I am running a 9t pinion and I thought about changing to a holmes 3300 stubby with a gear reduction unit and a esp anti-spur setup, but I don't want to slow down 2nd gear. It seems to me this would be the next evolution of aftermarket parts. Does anyone know if they are carried anywhere? I already ordered the underdrive gearset for the rear diff from rpp, but a slow 1st gear is what I would really like. Any help would be appreciated. Below are photos of the gearset in question. I was even thinking about flattening part of the shaft and finding a pinion to stick on there, but that is probably harder than it sounds in my head.

Best Regards,
Matt
