GPM Racing 7075-T6 Alloy Front/Rear Gear Box for Arrma 1/5 Kraton 8S (MAKX012NF/R)

Aluminium front & rear gearbox for ARRMA KRATON

This 34pc gearbox set is an RC-scale replacement designed for ARRMA KRATON 8S BLX MONSTER chassis, intended to secure and stabilise components around the front and rear differential areas. The kit uses machined aluminium parts to improve rigidity and thermal dissipation compared with standard plastic housings, while following the original geometry for straightforward disassembly and maintenance.

Primary role and fitment: the assembly stabilises front differential parts, damper mounts, anti-roll bar linkages and knuckle arms to reduce play and improve steering feel. High machining accuracy reduces internal clearances to promote smoother steering response without changing drivetrain layout.

Installation notes: the set follows original mounting points and fastener locations for direct replacement. Retain original bearings and internal gears unless wear indicates a full drivetrain service. Check fastener torque and thread engagement when installing to avoid stripping lightweight threads.
