The Traxxas Unlimited Desert Racer Rear Drive Shaft by GPM UDR237SN is produced from hardened steel #45 with controlled dimensions to ensure consistent power transfer from the centre gearbox to the rear differential. The component is specified to increase section modulus and material hardness to reduce shaft flex and improve fatigue life under cyclic loading.
Relative to the original item, this shaft provides an increased cross section and hardened material characteristics that raise resistance to bending and fatigue. The part retains stock mounting interfaces for straightforward installation by experienced hobbyists and technicians.
