Not sure where to post this, I suppose this is as good a place as any..
I was messin' around and found some 17mm hubs from TRAXXAS for other than emaxx/summit/revo set-ups.
here is what I found (taken from another site post)
"Whether you’re mounting 1/8-scale buggy wheels on your Slash 4X4 or adding super-sized tires to your Stampede, Traxxas’ new 17mm Hex Adapters make it easy to install a wide range of wheel and tire combinations on your Traxxas vehicle. Installation is simple and can be done in less than 15 minutes using the included 5mm hex wrench. The adapters’ unique splined design offers maximum strength when used with Traxxas wheels, and also fits any standard 17mm hex wheel. Rugged machined-aluminum construction and vivid blue anodizing combine custom looks with maximum performance.
The adapters are offered in complete sets to fully outfit one vehicle. Part number 5853X fits all 2WD Slash models, Stampede, and Rustler; 6856X fits Slash 4X4 and Stampede 4X4.
