This 105mm rear central dogbone drive shaft is an RC-scale drivetrain component machined to reduce mass while retaining structural strength. Each shaft is CNC-machined from Hudy Spring Steel and hardened to resist wear, then hand-ground and individually inspected to ensure concentricity and fit for tight drivetrain tolerances.
Designed for consistent behaviour under load, the shaft features milled weight reliefs to lower rotating mass where practical, and HUDY hardened pins to provide a durable pivot interface. The assembly is serviceable and aims to deliver predictable rear driveline characteristics for tuned setups.
Installation guidance: align the shaft with the rear differential and bearing carriers, ensure pins are fully engaged and retainers fixed, then rotate the hub assembly by hand post-install to check for any binding before full-speed use. The shaft complements chassis adjustments that change rear traction and handling feel.
As a drop-in for GTXE 2027 chassis, this 105mm CNC dogbone balances reduced mass with hardened construction to refine rear drivetrain response.
