This is the 170mm leaf under version of the BowHouse RC NCYota axle using the same shock and leaf over axle mounting locations as the RC4WD Yota axles, with an added leaf under axle mounting option. NCYota Axles use the same hardware as the GCM Racing TM8 axles. To complete your axle set, you will need to purchase a front axle housing, a rear axle housing, and two differential covers from our Shapeways store:

You will also need a TM8 hardware set from GCM Racing. Hardware sets are available through tinytrucks.com (USA customers), JS Scale (EU customers), or the GCM Racing web site (Canada and international customers outside of the US and EU):
