Coming from Avid and made for the HB D413 1/10th 4WD buggy is a 12mm aluminium hex set. Offering an innovative pin retaining system to hold the front drive pins in place the conversion does away with the annoying “pin dropping out to never be found again” the original front hexes sport. The front hexes are machined in a way to utilise an internal O-ring that holds the pin in place once the wheels are off. For the rear adapters the proven clamping system is used utilising a stainless steel 2-56 clamp screw. The chamfered edges of the 6061-T6 alloy parts make for easy wheel installation and each package includes a pair of 12mm hex front and a pair of 12mm hex rear adapters, three front O-rings, two 2-56 clamping screws, O-ring install instructions, and an Avid mini decal sheet.
