Cat On-Highway Truck Engines
Cat exited the on-highway truck engine market in 2009, but the C7 through C18 platforms have remained in active service ever since. Most of these trucks are owned by people who chose them deliberately — owner-operators, heavy-haul specialists, oilfield service operators, and small fleets that have stayed with what works. We support the full C-series truck range with ACERT calibration work, pre-ACERT tuning, delete preparation for export and off-road, and the calibration recovery that aging dealer support increasingly can't provide.
