Arrma is going big. Now that the legal stuff is over they seem to be rolling in high gear. My LHS has most everything Arrma already and is getting more and more all the time. I guarantee the aftermarket companies are already gearing up. Times are changing for Arrma and it is all for the better. They deserve it (and so do we).
I emailed back and forth a couple times with RPM about the senton mega front skid (broke 3 before I got a newer version which I haven't broke yet and should've based on the first 3) and was told they would look into it and "now that Horizon made it clear they were going to continue to support the ARRMA brand they would definitely look into making more products for ARRMA vehicles"
Maybe that's the kit for the senton blx 6s and not the senton 4x4 blx 3s. I think I found a part number for the new 3s blx stuff on fast eddys website, and maybe tower but I don't think it was available yet and the lhs here couldn't find it although they can get fast addy kits.
here's a complete list of replacement bearings for Senton/Granite 3s, including replacing steering rack bushings with bearings. I take no credit for this info, I saved it from another forum members post
