Description

Direct-replacement mainshaft 2nd gear for Borg-Warner/Tremec T5 World Class transmissions in the 2.95 first-gear family. A helical profile with precision hobbing and edge-relief delivers smoother 1–2 shifts and lower gear whine. Manufactured from SCM415 / SAE 8620 alloy case-hardening steel and carburized & quenched to a high surface hardness, it combines wear resistance with a tough core for long service life. Geometry and tolerances are OE-matched for a clean drop-in during rebuilds—ideal for restorations, daily use, and mild performance setups. Commonly found in GM ’88–’92 and Ford Z-spec applications (verify ratio family before ordering).
