Front and Rear Gearbox Kit for ARRMA KRATON 8S BLX MAKX012NF/R by GPM  [MAKX012NF/R]

High-strength gearbox upgrade for the ARRMA KRATON chassis

This 34pc gearbox set is an RC-scale replacement created for the ARRMA KRATON 8S BLX MONSTER platform, aimed at tightening tolerances and supporting components around both front and rear differential sections. Precision-machined aluminium pieces give improved stiffness and thermal behaviour over factory plastic housings while retaining stock geometry for easy removal and servicing.

Function and fit: the assembly reinforces front differential assemblies, damper mounts, anti-roll bar linkages and steering knuckle arms to cut play and refine steering feedback. Tight machining tolerances lower internal clearance, encouraging a cleaner steering response without altering the drivetrain layout.

Fitting notes: the kit uses original mounting points and fastener locations for a direct-fit swap. Keep existing bearings and internal gears unless inspection shows significant wear. Confirm screw torque and thread engagement when refitting to prevent damage to thin threads.

Suitable for regular maintenance or chassis upgrades, this aluminium gearbox set gives a direct replacement to reduce steering and suspension play while keeping access for routine servicing straightforward.
