Some that will hold up to 4s with either a castle 2650kv motor or a hpi tork 2200 kv motor... would teknos be better than these...[url]https://www.ebay.com/itm/1-10-Traxxas-Slash-VXL-4X4-Hardened-Steel-Front-Driveshafts-CVD-JC097/283369004743?hash=item41fa1bdec7:g:5ioAAOSwA3dYLoDd:sc:USPSFirstClass!91324!US!-1:rk:13:pf:0[/url] Thanks.
