AWESOMATIX A800 MMX 7075 Alloy Differential Gear Set for O-AP0003 - O-AP0003B by Factory Pro  [FP-O-AP0003B]

A800 MMX internal differential gears

This Factory Pro FP-O-AP0003B diff gear set provides direct replacement internals for AWESOMATIX O-AP0003 differentials, supplied as a matched set of 8pcs precision machined from 7075 alloy. The kit is aimed at hobbyists servicing RC-scale differentials on 1/10 electric touring chassis that use the O-AP0003 diff housing.

Fit these alloy gears to restore consistent tooth profile after wear or to upgrade from softer stock material for better resistance to common track wear. Assembly follows standard diff rebuild steps: inspect gear faces and runout, replace worn bearings and cups, then confirm correct mesh and backlash before sealing the unit.

Assembly tips: treat the 8pcs as a matched set, do not overtighten diff screws which can change preload, and verify even tooth engagement across the ring to avoid edge wear. These are RC-scale parts and are not intended for full scale vehicle use.

A practical upgrade for club racers and weekend tuners rebuilding AWESOMATIX O-AP0003 diffs who want the durability benefit of a harder alloy in routine track use.
