Overview: This is a precision machined heavy duty alloy rear clamping* RC hex set designed just for the Team Assicated DR10 and DB10. The looser steel cross pin tolerance allows you to tighten the wheel nuts without binding the bearings. The hexes do not lock onto the bearings, unlike the stock plastic hexes. * Uses heavy duty M2 alloy steel screws for the clamping (do not over tighten).
