Precisely forged from high-toughness alloy material with compact structure that resists deformation and cracking. The surface undergoes hardening and wear-resistant treatment for superior wear and corrosion resistance. Precision forming ensures accurate connecting positions and uniform force transmission, delivering sensitive and smooth shifting control. Compatible with the shift control system of heavy-duty truck transmission, it adapts to long-term use under heavy-load climbing and complex road conditions without looseness, stagnation or displacement. It features good interchangeability and easy installation, with strong load-bearing and impact resistance to meet the demands of high-intensity operating conditions.
