These GPM front and rear CVD drive shafts are manufactured from 4140 medium carbon steel and finished with a hardened black treatment to enhance surface strength and wear resistance. The design replaces the stock CVD dog bone and plastic wheel shafts with heavy-duty CNC machined steel wheel stub axles to reduce drivetrain play and improve torque transfer. Intended for hobbyists seeking a durable, serviceable upgrade, the components are compatible with small scale ARRMA models listed below.
