ARRMA MINI KRATON 3S (1/16) Differential Outdrive Set MAKM039SA by GPM  [MAKM039SA]

Outdrive construction and fitment notes

This aftermarket outdrive kit is made for ARRMA 1/16 MINI KRATON 3S platforms and intended solely for RC differential output use. Manufactured from nickel alloy, the components are aimed at improving wear resistance where the outdrives sit in front or rear differentials, and they are compatible with driveshafts that accept 2mm pins. Items are supplied as a matched pair to replace specific factory parts.

When installed, the firmer outdrives reduce torsional compliance between differential outputs and driveshafts, which helps preserve drivetrain geometry under load. Typical installation steps include removing the differential cover, withdrawing the worn outdrives, pressing the nickel-alloy replacements onto the differential outputs with the correct retention pins, and confirming pin engagement by manually rotating the assembly before final reassembly.

These parts are intended for hobby RC use and match factory service items ARA311193 and ARA-3294 for compatible ARRMA MINI KRATON 3S models.

For routine maintenance or light upgrades on the 1/16 MINI KRATON 3S, these nickel-alloy outdrives provide a straightforward replacement option that emphasises longevity and reliable power transfer.
