“A new design on the M4 was the introduction of a new suspension system, the Horizontal Volute Spring Suspension (HVSS). Designed to improve the shock absorbing action and maintenance, the tracks were widened from 16½ inch (41 cm) to 23 inch (57.5 cm). The original bogie consisted in two lower track wheels and one track return wheel on top, the HVSS had four lower track wheels. The top return wheels were built on to the chassis. M4's with the HVSS system were called 'Easy Eight's' after the test vehicles, E8.”
