1/16 ARRMA MINI KRATON 3S Differential Output Shafts MAKM039SA by GPM  [MAKM039SA]

Durability and drivetrain impact

This aftermarket outdrive assembly is produced for ARRMA 1/16 MINI KRATON 3S vehicles and is designed specifically for RC differential output applications. Crafted from nickel alloy, the parts aim to deliver enhanced wear resistance for front and rear differential positions while remaining compatible with driveshafts that use 2mm retaining pins. Components are supplied as a matched front/rear pair to replace the factory items listed.

Functionally, upgrading to stiffer outdrives reduces torsional flex between the differential output and driveshaft, which helps the drivetrain maintain alignment and consistent torque transfer during heavy loads. Standard maintenance installation involves removing the differential cover, removing the worn outdrives, pressing the nickel-alloy units onto the differential outputs with appropriate retention pins, and rotating the assembly by hand to verify smooth operation before reassembly.

These parts are intended for hobby RC vehicle use and correspond to factory service numbers ARA311193 and ARA-3294 on compatible ARRMA MINI KRATON 3S platforms.

For drivers aiming to reduce drivetrain deflection and improve longevity on the 1/16 MINI KRATON 3S, the nickel-alloy outdrives present a direct-fit upgrade focused on tougher, more consistent power delivery.
