Why Rebuild During Gear Assembly?

Installer’s Note: Reusing old bearings, synchros, or seals on a brand-new gearset is the #1 cause of premature gear wear and poor shift engagement. Refreshing all wearable components at the time of assembly protects your investment, maintains optimal gear alignment, and ensures long-term transmission health.
