ALBINS GR6 PRIMARY INPUT SHAFT 300M – HEAVY DUTY NISSAN GTR R35

Albins GR6 Primary Input Shaft – Solid Billet

Hollow input shafts (OEM and aftermarket) share a common GR6 failure mode: fatigue cracking around the stem, where the internal bore cuts cross-sectional strength right where launch loads peak. Albins machines this shaft as a fully solid stem from billet high-alloy steel, eliminating the hollow core entirely — no bore, no internal stress riser, no weak point — maximizing torsional strength and fatigue life through the critical failure zone.
