Teflon bushings
gaskets(possibly o-rings as well)
diff out drives(pending new out drives will fit typical bones better and last longer, but this is still a wear item)
Slipper pads
End caps(increased shaft angle will accelerate wear here - Losi 8 front for example)

The current outdrives accomodate a 9mm dogbone ball - this allows them to be used on the HPI Savage bones(and a few 1/8 truggies) and also "works" on the more typical 8mm bone. We are working on a harder, lightened out drive version with an 8mm outdrive bore for the more typical 1/8 center shafts. "one size fits all" was the intention initially. We are working on tweaks and will continue to do so. We are working on shimming scenarios for fitment in some larger diff openings, as well as other enhancements. The product will be tweaked and updated throughout is life, as every product is. :)
