ARRMA KRATON 8S BLX Aluminum Rear Gearbox MAKX013 for Strength by GPM  [MAKX013]

Rear Gear Box Reinforcement for ARRMA KRATON 8S BLX

This rear gear box assembly is an upgraded replacement tailored for ARRMA KRATON 8S BLX MONSTER TRUCK applications. Machined aluminium components stabilise the rear differential and provide robust attachment points for the suspension linkages.

Engineered for functional durability, the 6061 T6 aluminium construction helps move heat away from the gearing and keeps mating surfaces dimensionally consistent. Tight machining tolerances reduce slack at the gearbox-to-diff interface and at suspension mounts, which supports repeatable rear-end behaviour.

The kit includes the fasteners and shafts required to swap out the stock rear gearbox parts without additional hardware purchases. Refer to the parts list and original references below to verify fitment and help during the installation process.

For hobbyists seeking improved longevity and a firmer rear mounting solution, this aluminium rear gear box offers a direct-fit replacement for ARRMA KRATON 8S BLX models. Use the supplied hardware and the original part references to confirm correct assembly and follow recommended service procedures when setting up the rear differential and link geometry.
