This aftermarket bearing kit is designed for 1/18 TRX4M crawler platforms and provides sealed steel bearings for wheelbox, axle and drivetrain locations to lower internal friction and reduce ingress of dust and debris during trail use.
The kit includes the necessary sizes to replace bearings across the model in a single service session. The sealed steel design aims to simplify upkeep compared with open bearings while maintaining the original fit and mounting dimensions for the listed TRX4M models.
If you are replacing bearings on a listed TRX4M 1/18 vehicle, this sealed steel set supplies the common sizes for a full swap and helps keep the drivetrain running smoothly on demanding terrain.
