ARRMA Mini Kraton 3S Front Differential 12/30T 20CrMnTi+7075 MAKM1230FS by GPM  [MAKM1230FS]

Durable front diff for Mini Kraton 3S

This replacement front differential is produced for ARRMA Mini Kraton 3S and is listed as MAKM1230FS. Internal bevel gears are manufactured from 20CrMnTi steel while housing and support parts are CNC 7075-T6 aluminum, using a spiral-cut 30T ring gear and a 12T pinion at 0.8 module. The item is supplied fully assembled and includes bearings for straightforward fitment.

The 12/30T ratio and 0.8 module match driveshafts designed for 2 mm pins; both large and small bevel gears receive a hardened black surface treatment to better resist wear under high torque. This aftermarket unit is designed to replace factory components ARA-3294 and ARA-2672 in compatible ARRMA Mini Kraton 3S kits.

Diff oil must be added by the user. Suggested starting viscosities are front 50K CST, rear 30K CST, and centre 500K CST or 1000K CST depending on desired lock. Small parts noted as pre-assembled arrive in place, and applying thread locker on screws is recommended to maintain reliability during aggressive use.

For owners aiming to reinforce the Mini Kraton 3S front drivetrain, this front differential supplies hardened gearing and alloy support pieces tailored for the ARRMA 1/16 chassis; remember to fit diff oil and secure fasteners during installation.
