Rosenbauer America’s new Viper SA fire truck will be equipped with Meritor’s high-strength RS180 series single-reduction rear axle, the companies announced.

The 100-foot Viper SA is equipped with a 1,500 gallons-per-minute pump and a jack spread 16.5 feet long. The Viper SA is fully capable of storing the National Fire Protection Association requirement for either an 85-foot quint complement or a 115-foot aerial complement of ground ladders. The unit also has more than 150 cubic feet of compartment space. Equipped with four H-style outriggers, the Viper SA can operate uphill and downhill.

Meritor’s new 35,000-lb. RS180 series axle is engineered for high-demand fire and rescue vehicles. The axle is built with a stamped steel-fabricated housing to handle these high-weight and high-performance applications and includes Meritor’s 180 series differential carrier. It is available with standard or wide-track housing options, as well as Meritor cam brakes and industry-familiar U-series wheel-ends. An optional driver-controlled differential lock (DCDL) is available to enhance traction.
