Product Overview
The Truck Torque Rod is a critical component in heavy-duty truck, trailer, and commercial vehicle suspension systems.
It connects the axle to the vehicle frame, controls axle motion trajectory, and withstands longitudinal forces, lateral forces, and torsional loads during operation.
Its strength, rigidity, and durability directly affect vehicle safety, tire wear, and suspension system service life.
With over 40 years of casting manufacturing experience, Sangroove (Jiangsu) Machinery Co., Ltd. specializes in producing torque rods, torque rod brackets, and heavy-duty chassis components, providing high-quality solutions for global commercial vehicle OEMs, axle manufacturers, and aftermarket customers.
