Counter Shaft Mazda BT50
Description
OE-spec counter shaft for the Mazda BT-50 manual transmission. The integrated helical gear sections are precision-hobbed and edge-relieved, while the journals, bore, and locating faces are precision-ground to ensure quiet, rigid mesh and high efficiency across the ratios. Made from SCM415 / SAE 8620 alloy case-hardening steel and carburized & quenched to HRC 58–62 for superior wear and pitting resistance. Built to OE geometry and tolerances for true drop-in replacement during rebuilds.
