The Freightliner 122 SD

The Freightliner Lineup

The 122SD is tough. Test after test demonstrates it. The components, systems and entire truck have been subjected to an array of product validation tests to ensure the 122SD delivers the expected function, performance and reliability. The result is a durable and safe cab that meets stringent A-pillar impact, rollover and back wall impact tests. Plus, the vocational chassis includes a robust backbone with a complete offering of single and double channel frame rails. This provides a tensile strength of up to 120,000 psi and an RBM ratio up to 5 million inch-pounds per rail. So it can handle the abuse of a typical job site. No problem.
