Yeah Racing Axial SCX24 Steel Transmission Gear Set (51T & 19T)

This transmission gear set is build solid. The Yeah Racing Axial SCX24 Spur & Pinion Gear Set (55T/11T) did not fit onto the gear. I could not get that gear to slide down at all, the plastic stock gear slid right into place and is currently working just fine. I paired this up in the Treal gear box with FastEddy bearings and they are ready to move around this behemoth of a crawler, once I get a new front axle on.

A MAIN FTW AGAIN!!! If you have a stock scx24 transmission case, it goes right in, on side is maybe 1mm or less longer on the spur gear side, be mindful the driveshaft cup will not go on if installed backwards lol. Does have super tight tolerance on the motor can side of the transmission case for the driveshaft cup, I’m gonna let mine burn and melt its own gap, clean it up as I notice it. But I just picked up my crawler after installing the gears, my old one were badly stripped, and the truck did a full forward a revise twist on my fingers, no binding or anything. Man I love A MAIN for the easy part access. I’m not just going around finding parts, I look at what I exactly need so I don’t upgrade tons of parts that don’t need it. I very highly recommend this gear set for anyone in need of new gears, metal also. I’m pretty sure they fit perfectly into the stock bearings as well, my bearings are burning up so I need to find a new set. Thank you tons A MAIN!!! Even the shipping is reasonable and reliable.
