Ultimate Drivetrain ReinforcementThese hardened dogbone driveshafts deliver competition-grade reliability for Losi 1/8 LMT trucks. The 4340 chromoly steel construction undergoes vacuum heat treatment to achieve 55-58 HRC surface hardness, providing enhanced durability compared to stock driveshafts. The hollow-core design reduces unsprung weight while maintaining structural integrity under high-impact forces.
