Strength You Can Trust: JM USA Suspension Parts for Heavy-Duty Truck and Trailer Applications
In the heavy-duty truck and trailer industry, reliability isn’t optional — it’s everything. JM USA’s suspension components and fasteners are engineered and sourced to keep fleets rolling safely, mile after mile. From hot-forged bolts and cap screws to critical suspension pins and bushings, every product reflects JM’s commitment to compliance, performance, and controlled quality.
North American Quality — Backed by Controlled Sourcing
JM USA specializes in the manufacture of headed fasteners, including bolts and cap screws, produced through hot-forged processes using 100% U.S.-melted and poured steel. These are built in North America under our ISO 9001:2015–certified quality system, ensuring full traceability and compliance with ASTM, IFI, and ISO standards.
To complement our forged portfolio, JM USA also offers a select range of suspension components and trailer parts — such as pins, bushings, and alignment bolts — sourced from qualified and audited partners under JM’s direct control. Each item is verified to meet industry specifications and undergoes JM’s own inspection, certification, and traceability protocols before reaching our customers.
The result: a unified suspension line that delivers the best of both worlds — in-house manufacturing excellence and rigorously controlled distribution quality.
Built to Perform in Every Mile
- Threaded Pins and Bushings – precisely machined and inspected for torque consistency and dimensional accuracy.
- Spring Pins and Equalizer Shafts – built to OEM dimensional standards and proven under vibration and load cycles.
- Square Head and Hex Head Bolts – hot-forged Grade 8 parts with full mechanical certification.
- Pivot Bolts and Torque Rod Bolts – engineered for durability and alignment integrity in critical suspension systems.
Each component meets or exceeds applicable standards such as ISO 898-1, ASTM A193/A320, or SAE J429, and aligns with the interchange specifications of major OEM references like Hendrickson, SAF-Holland, Kenworth, and Fruehauf.
