FAQ

Does ARA311177V2 fit the front or rear? ARRMA specifies this differential for use in either the front or rear position on compatible GROM vehicles.

Is the differential supplied assembled? Yes. It arrives factory assembled, grease-filled and ready to install.

Are bearings included? Yes. The differential is supplied with bearings to make installation faster and more convenient.

What is different about the V2 differential? The V2 design features steel internal gears and pins for improved drivetrain durability compared with the earlier internal design.

Is the complete differential made from metal? ARRMA specifically identifies the internal gears and pins as steel. This does not mean that every part of the differential assembly or main gear is metal.

Is this an oil-filled differential? No. ARA311177V2 is supplied filled with grease. ARRMA offers a separate oil-filled GROM differential, so check the part number carefully when comparing the two designs.

Does one package replace both differentials? No. This package contains one assembled differential. Two units are required when replacing both the front and rear differentials.

Will it fit every ARRMA GROM model? GROM drivetrain specifications can vary between models and production versions. Confirm ARA311177V2 in your vehicle manual or official exploded parts diagram before ordering.

What can cause repeated differential damage? Common causes include drivetrain binding, damaged input gears, incorrect gear mesh, oversized tyres, abrupt throttle use and continued driving when the differential begins clicking or slipping.
