ARRMA 1/16 MINI KRATON 3S Front/Rear Differential Outdrives MAKM039SA by GPM  [MAKM039SA]

Nickel alloy outdrive summary

These aftermarket outdrives are manufactured for ARRMA 1/16 MINI KRATON 3S models and are intended for RC-scale differential output use. Machined from nickel alloy, the units aim to improve wear resistance in front or rear differential locations while remaining compatible with driveshafts that use 2mm pins. The components are supplied as a matched pair suitable for replacing the listed factory part numbers.

In practical use, fitting stiffer outdrives reduces torsional flex between the differential and driveshaft, helping to preserve drivetrain alignment under load. Fitment is straightforward for routine maintenance: remove the differential housing cover, extract the worn outdrives, press the nickel-alloy units onto the differential outputs using the correct retention pins, verify pin engagement and rotate the assembly by hand before reassembling to confirm smooth operation.

The parts are intended solely for hobby RC vehicle use and are listed as replacements for factory items ARA311193 and ARA-3294 on compatible ARRMA MINI KRATON 3S platforms.

For technicians tuning the 1/16 MINI KRATON 3S drivetrain, these nickel-alloy outdrives provide a direct replacement option focused on durability and consistent power transfer across front and rear differentials.
