About the Volvo I-Shift with Crawler Gears
The Volvo I-Shift with Crawler Gears is the heavy-duty variant of I-Shift — 12 standard gears + 2 ultra-low 'crawler' gears for extreme starts and grade climbs. Used in Volvo VNX (heavy haul) and VHD (severe-duty vocational). Crawler gears let a fully-loaded heavy-haul rig start on a steep grade — something a 12-speed AMT alone struggles with. Direct competitor to Eaton Fuller 18-speed manual in heavy-haul applications.
