The Gates Micro-V V-ribbed belt is a heavy-duty accessory drive replacement for 2008–2012 Freightliner Cascadia trucks with Detroit Diesel DD15 engines. Intended to handle water pump, alternator and A/C duties under heavier loads, the HD designation supports more demanding operating environments. The belt retains the V‑ribbed profile required by the accessory pulleys on these applications.
