ARC R12 Super Smooth Gear Diff Building Tip @ Quantum!

ARC factory driver shares building tips on making a super smooth gear diff for the ARC R12. Standard thickness of a production diff bevel gear is at approximate 4.26mm. Sanding down the bevel gear flat side to between 4.12mm to 4.15mm will make the gear diff action super smooth. When sanding down the bevel gear, do it in a 8-figure direction so that the flat side stays flat. Enjoy your ARC R12!
