The Gates Micro-V V-ribbed belt is a heavy-duty accessory drive replacement for 2013–2015 Freightliner 108SD trucks with Cummins ISL9 diesel engines. It is specified for water pump, fan, alternator and A/C accessory duties and labeled HD to address higher-load environments typical of vocational or heavy-service applications. The belt maintains the V‑ribbed profile required by the accessory pulleys.
