This front lower reaction thrust rod is a key chassis suspension component for FAW Jiefang J6 heavy trucks. It connects the axle and vehicle frame to transmit longitudinal force and torque. It limits axle displacement during acceleration, braking and driving on bumpy roads, stabilizes the axle position and optimizes vehicle handling performance. The rod body is made of thick seamless steel pipe with forged end joints and built-in high-performance rubber bushing. It can absorb impact and vibration under long-haul heavy-load operation, reducing chassis shake and knocking noise. Each reaction link undergoes tensile test, fatigue test and bushing performance inspection before delivery. It solves common problems such as axle shifting, chassis abnormal knocking and premature bushing failure, serving as an essential replacement spare part for chassis suspension overhaul.
