This transmission kit is engineered for hobbyists seeking a durable driveline upgrade on the ARRMA MOJAVE GROM. CVD drive shafts are machined from 4140 carbon steel to provide enhanced torsional stiffness and abrasion resistance. Hex adapters are aerospace grade 7075-T6 aluminum for secure, low tolerance wheel mounting. The kit replaces fragile dog bone and plastic wheel shafts with CNC machined steel wheel stub axles for higher load capacity. Pins have been increased from 1.5mm to 2mm to reduce failure points. Reinforced cup joints are included for reliable differential connection and versatile fitment.
