XRAY 355633-XH Rear Central Dogbone Drive Shaft 98mm Hudy Spring Steel  [XR-355633-XH]

Rear central dogbone drive shaft overview

This 98mm rear central dogbone drive shaft is an RC-scale replacement part machined from Hudy Spring Steel and hardened for wear resistance. The component is weight-reduced by strategic machining and hand-ground for tight dimensional tolerances, preserving strength while trimming rotating mass.

The unit uses HUDY special hardened pins and a 6° h-pin configuration specified in the part name, intended to locate and retain the dogbone reliably under load. Because each shaft is CNC-machined and individually inspected, it is suitable for competitive track setups where consistent geometry and durability matter.

Installation notes: the shaft replaces the rear central dogbone in compatible GTX 2026 setups and interfaces with standard dogbone cups and differential assemblies on 1/10 scale touring car drivetrains. Verify pin fit and bearing alignment during installation and re-check after initial run-in.

For GTX 2026 rear drivetrains that need a precision, hardened central shaft with reduced mass, this XRAY 355633-XH unit provides a durable, track-ready option that simplifies tuning of rotational inertia and maintains reliable pin retention under race loads.
