Gpm is a great company to go through for your rc aluminum parts. They have a wide selection of parts and colors and are great to deal with. They keep in contact if you have any issues and get them handled.

What parts are replaced by this kit?

The kit replaces the rear gearbox housings and provides the associated fasteners that secure the rear differential and suspension link mounts on ARRMA KRATON 8S BLX MONSTER TRUCK models.

Why use 6061 T6 material for these components?

6061 T6 aluminium is selected for its dimensional stability and thermal conductivity, improving alignment under load and assisting heat dispersion compared with typical plastic parts.

Are all necessary screws supplied?

Yes. The package includes a range of stainless steel screws and shafts as listed in the packing section so you can replace the stock fasteners without additional purchases.

Will installation change vehicle behaviour?

The stiffer aluminium housing reduces drivetrain compliance and may change rear-end feedback. After fitment, check diff backlash and suspension geometry and adjust settings such as damping or toe to suit your driving style.

Which original ARRMA references are provided?

The original part numbers listed are ARA310935 and ARA320474; use these to verify component compatibility before installation.
