HVSS stands for Horizontal Volute Spring Suspension. This suspension type replaced the vertical volute spring type and was used in later models of the M4 tank. However, as all M4A3s armed with the 76mm gun (Sherman IVA in UK service) were fitted with wet stowage, it is true to say that a M4A3 (76) HVSS was less likely to brew up. No thanks to the suspension though Mattias
