This is the second version of the Wrapter for Gmade R1 Rock Crawler.
The Wrapter is an adapter that allows you to use Axial Wraith c-hubs, knuckles and universals drive shaft on the Gmade R1 axles. This however requires some modification on the universals drive shafts.
The price is for a pair of Wrapters, so you only have to purchase one for each axle.
Instructions how to modify the universals and install the Wrapters can be found here:
