The ARRMA KRATON 6S EXB is known for blistering speed and rugged use. The GPM MKV61200S steel differential gear set uses tough 20CrMo material to resist wear during aggressive runs, giving a dependable upgrade that holds up under hard use.
Gears in this set are produced to tight tolerances so teeth mesh cleanly for quieter, smoother operation. The heavy duty steel cross shafts included add strength to the diff assembly, helping the truck retain consistent drive characteristics at high speed.
This kit is intended for 29mm diff cases and works with both limited slip and open differential layouts. It is a practical choice whether you are refreshing worn internals or upgrading for tougher running conditions.
