Freightliner Specialists
Freightliner is the most common truck on the corridor, and we service the full lineup from long-haul Cascadias to M2 vocational

Whether it’s a regen fault, a DT12 that won’t shift, or an in frame on a DD15, we diagnose the root cause and fix it right without the dealership wait.
