This GPM MKV61034S/2 front and rear differential set is engineered to reinforce the ARRMA KRATON 6S drivetrain. Components use 20CrMnTi hardened steel for the gear train combined with 7075 alloy housings to extend service life under heavy use. The units come fully assembled with helical gearing at a 10T/34T ratio and a module of 1.3mm to maintain consistent mesh and torque distribution. A 29mm differential housing provides dimensional stability and predictable behaviour during aggressive runs. Differential oil must be supplied separately in accordance with the ARRMA service recommendations.
