Spartan Independent Front Suspension (IFS)
Safety & innovation without compromise
Engineered to be the safest chassis in the industry. Shortest stopping distance. Improved cornering. No bump steer.
Industry leading 55 degree cramp angle produces a 22% shorter turn radius than the competition.
Improved Ride & Handling
Performance proven air-spring technology produces the smoothest ride and handling. The reviews speak for themself. See the proof below.
“A big factor in Saanich Fire’s decision to use the IFS on Engine 3 was stability and ride comfort. During emergency response the Officer has to be able to safely and easily view all details of the incident on the mobile terminal. A smooth stable ride is imperative to safe operations & response. The option to increase our wheelbase length to allow better body cabinet configuration was a bonus as well.”
- Deputy Chief Dan Wood, Saanich Fire Department
|Open platform. Non-proprietary.||Availability||Closed platform. Proprietary.|
|Engineered to withstand the severe on-road use of the fire service.||Application||Designed for off-road use.|
|Performance proven airspring technology.||Architecture||Mechanical high-stress torsion bar.|
|Independent wheel movement so all tires remain in contact with ground. Shorter stopping distance. Improved cornering. No “bump steer.”||Safety||High-stress torsion spring prone to fracture.|
|Lowest TCO. Replacement parts are “industry standard” components, in stock, reducing down time.||Total Cost of Ownership
|Proprietary parts cost more. Longer lead time on replacement parts. Geometry & set-up is not easily maintained or adjusted.|
|Up to 55 degrees even with addition of front intake.||Cramp Angle||Up to 45 degrees. Cramp angle significantly reduced with front intake.|
|22% shorter turn radius.||Maneuverability||Greater turn radius.|
|Variable rate air springs & custom tuned shock absorbers. Impact on 1 wheel does not affect steering.||Ride Quality
|Mechanical torsion spring produce harsh ride for occupants & equipment.|
|Chassis height is maintained regardless of load.||Ride Height||Chassis height varies with load.|
|Ability to lower up to 4” to reduce step height (ingress/egress) & access to equipment.||Kneeling (Lowering)||Unable to kneel or lower.|
