Description
The CR12 Main Drive Gear Shaft is a replacement gearbox shaft for the Team Associated CR12 rock crawler platform, also fitting the MT12 Monster Truck and MT12 Monster Van. This shaft supports the main drive gear inside the transmission case, carrying the load as power is transferred from the motor through the gear train to the front and rear drive shafts. Machined from hardened steel, it is engineered to resist bending, twisting, and wear at the bearing surfaces even under the repeated torque spikes that come from climbing rocks and crawling over obstacles at low speed. A straight, true shaft keeps the main gear running true and reduces unwanted gear lash, vibration, and premature tooth wear caused by a bent or worn original part. This is a direct replacement for a damaged or worn factory shaft, restoring smooth transmission operation without needing a full gearbox rebuild. For crawler owners chasing extra durability, pairing a fresh shaft with a new main gear and bearings is an easy way to tighten up the whole drivetrain and keep power delivery consistent on technical terrain.
