WG2212220136 1st/2nd gear shift fork shaft is precisely forged from high-quality alloy steel, featuring high overall density, strong toughness, and excellent compression and bending resistance with no easy deformation.

With professional quenching, tempering and high-frequency quenching treatment, it has high surface hardness, outstanding wear resistance and impact resistance, capable of enduring the load of frequent gear shifting for a long time.

The shaft is finely ground with high machining accuracy and standard coaxiality, sliding smoothly and steadily. It realizes sensitive switching between 1st and 2nd gears without stagnation or abnormal noise.

Manufactured in strict accordance with original factory dimensional standards, it enjoys good interchangeability and easy installation. It effectively prevents gear jumping and gear slipping with superior durability, being an optimal replacement part for heavy-duty truck gearbox maintenance.
