lass 8 truck makers said they are paring away the number of component suppliers and shifting to integrating modules and systems with their chassis instead of simply assembling parts.

The truck makers told Transport Topics the change, which is reshaping the way customers specify components for, or “spec,” trucks, is intended to reduce manufacturing complexities and warranty costs and improve profits and the performance of the big rigs.

The new standard spawned redesigned engines that often ran hotter and added emissions-reduction components.
