ResponseMaster

IFS 20K, 22K and 24K

Specify IFS instead of the Ifs2400s Ft Arbsolid axle and leaf spring systems.  Don’t let the slick marketing fool you.  Whether it’s a fabricated axle with leaf springs or a forged axle with leaf springs, this is outdated technology suited for dump truck and waste haul applications not for a modern vehicle responding to an emergency in which lives are on the line.

The ResponseMaster® IFS family for custom fire and rescue vehicles combines refined ride quality and rugged design. Superior maneuverability and handling increases safety for the fire fighter and reduces response time in the most demanding conditions.

Reyco Granning has more than two decades of industry-leading experience manufacturing IFS suspensions. The ResponseMaster® family of systems exceeds the 70% US content necessary to meet the 2020 Federal Transit Administration regulations for Buy America content.

Safety

  • Independent front wheel movement. Unlike an I-beam suspension system in which both wheels are connected by a rigid axle, when one IFS wheel bounces the corresponding wheel is unaffected allowing it to continue straight and smooth. The benefit is improved ride, handling and tire wear.
  • Dynamic camber change during cornering, which allows the tires to “bite” into the pavement at a more aggressive angle helping the vehicle through a turn. On an I-beam suspension, the camber does not adjust and is maintained through the turn, thus cornering capabilities can be compromised in tight turns leading to instability.
  • Lower unsprung mass so chassis harshness and vibration are reduced when compared to I-beam axle excitation, providing better protection for equipment and a smoother ride for passengers.
  • Standard with 17” disc brakes, which reduces stopping distances and brake fade.

Maneuverability

  • An industry-leading 55º wheel cut/angle with 385/65R 22.5 tires provides unsurpassed maneuverability and a tighter turn capability. With increased turning capabilities, crews can get into position more quickly.

Serviceability

  • Adaptable suspension design elements like alternate cross members, allow easy configuration to accommodate multiple engine, turbo and transmission combinations.
  • Removable lower cross members allow easy access to transmission servicing, whereas competitive suspensions require dropping the entire suspension.
  • Standard parts in stock at Reyco Granning like kingpins, bearings, knuckles and hubs mean there’s no long wait for specialty parts to get the truck back on the road.

Additional Benefits

  • Reduced weight and maintenance over competitive product
  • Automatic height control
  • Ride height and axle rate stiffness adapt to changing road conditions on loads
  • Ability to exhaust the air and kneel
