SIV Ambulances


The Future Follows Us.


SIV is a Pennsylvania ambulance manufacturer building the SIV Responder (Medium Roof) and SIV Responder XL (High Roof) Type II Ford Transit ambulances. We’re backed by more than 500 completed remounts and years of experience inside the ambulances agencies rely on every day.

SIV designs, engineers, and builds both models around the way EMS crews actually work, shaped by direct input from working EMS chiefs, EMTs, and paramedics.

The SIV Responder has completed a full battery of crash and sled tests at Calspan. The testing covered the patient compartment, seating, cabinetry, oxygen and equipment mounts, floor structure, and cot-mounting system.

Remounting Is Where We Started

SIV remounts Type I, Type III, and Medium Duty ambulance modules onto new chassis, refurbishing and modernizing each module for its next service life.

Remounts can include:

  • Chassis replacement
  • Electrical system upgrades
  • Flooring, cabinetry, and upholstery
  • Whelen warning and scene lighting
  • HVAC
  • Paint and graphics

We work with modules from nearly every major ambulance manufacturer, including AEV, Wheeled Coach, Horton, Road Rescue, Braun, Medix, Demers, Leader, and others.

Built by SIV. Backed by SIV.

Our relationship with an ambulance doesn’t end when it leaves the building. SIV provides manufacturing, remounting, service, parts, collision repair, and fleet support from our facility in Langhorne, Pennsylvania. When an agency calls SIV, whatever brand they drive, our goal is simple: solve the problem and get the ambulance back where it belongs, on the road.
