The Equalizer American Design Suspension Parts from Jining Bst Machinery Co., Ltd are heavy-duty components designed for tandem axle trailer suspensions, replicating the torsion-style geometry of U.S.-made systems. These parts include equalizer bars, shackle straps, and mounting brackets, manufactured from high-tensile steel to handle dynamic loads up to 10,000 kg per axle. The design allows load sharing between dual axles, reducing tire wear and improving ride stability.
The components are made from ASTM A572 Grade 50 or SAE 1045 carbon steel, with heat treatment to achieve a minimum yield strength of 345 MPa. Surface finish is typically shot blasted and powder coated in black epoxy for corrosion resistance. Dimensions follow U.S. standard trailer suspension profiles, including 2-inch wide equalizer bars and 3/4-inch diameter shackle bolts. Tolerances on hole centers are ±0.5 mm, ensuring compatibility with common leaf spring assemblies.
These parts are purchased by trailer manufacturers in North America, Australia, and Southeast Asia for retrofitting or new build applications. Buyers typically order in quantities of 200 to 1,000 sets, packed in bulk cartons with foam inserts. Trade terms are commonly FOB Qingdao or CFR destination port. Lead time averages 30 to 45 days. No certifications such as ISO or SGS are confirmed in the listing; buyers must request test reports for load capacity and fatigue endurance.

Before ordering, verify the material grade, heat treatment process, and dimensional conformity to U.S. trailer suspension standards. Request material test reports (MTRs) and hardness certificates for each component. Do not assume compliance with SAE or DOT standards without documented proof. Confirm that the equalizer bar geometry matches your existing leaf spring setup.
Confirm Incoterms - FOB Qingdao is typical. Lead time averages 30 to 45 days depending on production queue. Payment terms are often 30% advance with balance against shipping documents. Ask for packaging details: each set should be individually wrapped and boxed to prevent scratching during transit. Avoid bulk pallets without internal dividers.
Inspect components for surface cracks, weld defects, or uneven coating before installation. Use a micrometer to check hole diameters and bar thickness. Request a sample batch for field testing under simulated load conditions. For export compliance, obtain a certificate of origin and a declaration of conformity to relevant safety standards such as FMVSS 121.
